Fixed in the repo. Just forgot to git add.

All systems in internal memory are stored on the same partition. That means all of them have to support f2fs, if you formatted your data to f2fs. Ubuntu doesn't work because its kernel doesn't have f2fs support. I didn't do any testing with f2fs, because I'm not so keen on wiping my whole device and I don't think it is worth the hassle.

Speaking of, does the f2fs test build work fine, assuming all your ROMs support f2fs?
[Nexus 7 Original Development] ironmaskusa:
I only tried it beforehand of formatted main partition. I actually had slimkat F2FS work once somehow.. Then I tried to do the Legolas kernel with it and it gave me the decryption storage password prompt. So then I gave up on the test version of multirom you released.. But now I'm willing to give it another spin and will let you know by the end of the weekend.

Thanks for helping.
[Nexus 7 Original Development] dareino:
I was using it as a data only on a primary but was unable to add any secondary roms . Some errors were the decrypt message or non-kexec kernel......

keep up the good work!

[Nexus 7 Original Development] ironmaskusa:
OK so I tried to install it and I got the special feature in advanced to show multiroms section and then installed slimkat all f2fs as a ROM and rebooted. I tried loading it and it gave me an error log. I tried to access the multirom folder to copy and paste it in, but for some reason it wouldn't let me in the folder with file manager.. Dunno.. It says I'm on multirom v22b though.. Because when I uses flashify to install the test and rebooted to recovery it didn't actually have multirom installed although the multiroms button was there under advance menu. I pressed it and it too me multirom was not installed so I went to multiromming manager.apk and installed 22b. Hope you can make sense of this? Thanks
[Nexus 7 Original Development] Fuzzra:
I just had the same problem. It occurs with both v22b and v23. It seems to happen if a kernel is changed - either the primary or secondary being replaced will cause the secondary to fall to boot with an error about no run-on-boot scripts.

Error dump is attached.
[Nexus 7 Original Development] ironmaskusa:
Looks similar to mine.
[Nexus 7 Original Development] Tasssadar:
Hm, gonna need a few more logs. Firstly, try to access adb while in MultiROM menu (must be enabled in recovery -> advanced -> MultiROM -> Settings -> Enable ADB).

If you are able to connect to adb while in multirom's boot menu: get me output of this command, run it in adb shell:

blkid; echo $?

If not, but you can access adb while in recovery: get me output of this command, run it in adb shell:

/sdcard/multirom/busybox blkid; echo $?

Tell me if the log is from multirom's boot manager or from recovery and which partitions do you have formatted as f2fs.
[Nexus 7 Original Development] Fuzzra:
Sorry for being a bit slow to get back.

Within multirom the output is just a lonely 0

From recovery it returns:

/dev/block/mmcblk0p7: TYPE="vfat"
0

I have system, cache, and data formatted as f2fs.
[Nexus 7 Original Development] ironmaskusa:
Same for me as well. Not sure.
[Nexus 7 Original Development] Tasssadar:
Flash this MultiROM and try it again: http://tasemnice.eu/bordel/multirom-20140418-v23a-f2fstest-grouper.zip

Btw, I'm trying to get F2FS working on grouper, and then I will add it to other multirom-supported devices - it should work the same on all of them.
[Nexus 7 Original Development] ironmaskusa:
I haven't tried this yet, but I think that some of the problem may be that these nodded F2FS ROMs aren't multirom supported. For instance; slimkat's ROM for F2FS original post implies it.
[Nexus 7 Original Development] Tasssadar:
There's no way for ROMs to "support MultiROM", aside from having kernel with hardboot patch, and that is relevant only if you install it as a primary ROM* and that won't cause it not to boot. I know what why it was failing to boot, busybox's blkid didn't know F2FS and MultiROM thought empty output meant blkid failed to run and aborted the boot. That testing version should be fixing that.

* This is true on all other devices, but some 3rd-party kernels on grouper might require both ROMs to have patched kernel. If you use patched kernels from the MultiROM app or this thread, you need only primary ROM's kernel to be patched.
[Nexus 7 Original Development] Stereo8:
This. Whenever I tried MultiROM with SlimKat F2FS, it just plain didn't show up.

The multirom recovery can't see the Ubuntu iso so i cant flash it, what do i do?
[Nexus 7 Original Development] Jerreth:
I have question and im not sure where to ask. I am curious about the differences between the Ubuntu versions in multirom manager. I see trusty (devel) and another that's customized and another demo and a generic does anyone know whats what?
[Nexus 7 Original Development] physwizz:
f2fs

I'd like to be able to format a usb stick as f2fs so I could try to run an external rom from it but I haven't been able to work out how to do it. Does anyone know how I can format a usb stick to f2fs?
[Nexus 7 Original Development] ironmaskusa:
Good question, not sure if that's possible unless it is implemented in multirom f2fs version and that's not even working right as of now.
[Nexus 7 Original Development] kyelo2:
Puppy Linux Precise-5.7.1 can format a USB stick to f2fs. You can D/L a .iso from http://bkhome.org/blog2/?viewDetailed=00346, burn the 156 MB .iso to CD-R and run Puppy Precise 5.7.1 from the CD.

Menu/System/GParted understands f2fs and can do the formatting for you.

.
[Nexus 7 Original Development] physwizz:
Thanks for that. I only hope it works from my imac.

Edit; I'll have to buy a usb keyboard because Puppy doesn't like the imac bluetooth keyboard.
[Nexus 7 Original Development] fingerr:

[Nexus 7 Original Development] physwizz:
OK I managed to partition a usb stick in 2 halves. One half ext4 and the other half f2fs. TWRP can only see the ext4 partition.

Hi [MENTION=3418703]Tasssadar[/MENTION]

if you recall a while back, i was trying to get kexec-hardboot working on the Htc One X,

and it's been working great since... but now i wanna also port this to the hox,

Although I've got multirom working, TWRP is another problem since our partition is only 8mb big while the recovery image is 11mb...

however i've got past this by using kexec to boot the recovery removing the partition size limitation...

anyways, I was wondering if it would be possible to add the recovery to the boot list in Multirom??

for that can you explain to me the structure of multirom/roms/*? and if it's even possible?

[Edit]

I got TWRP to boot & i can flash secondary roms(except i dont have enough space)..

but I got the structure... so i cleared it and replaced boot.img with the recovery.img [as i want to boot the recovery from multibo](obv renamed it)..

but when i choose to boot it from multirom, main rom boots??

Also, I do have kexec patch.

[/Edit]

[Edit2]

I've made changes to multirom.. which probably is causing it to crash....

im guessing in consequence to that.. the kernel default boot continues thus it wont boot TWRP img

Ill verify that 2night.

also, before i go editing half the code.. is there a way to enable /sdcard support...

since our /data partition is only 2gb large.

but we have a built in sdcard

[/Edit2]

Finally, im considering moving most of the recovery functions into AromaFM, to make it more portable,

how plusable is that.. since it will be a problem managing formatting and mounting from rom.zip script

I've took a bit of time to look at twrp and i know you move mount binary to avoid mounting the real partitions...

though i didnt yet find that actual function in the recovery in twrp.. however, i know in Philz recovery mount is done using mount function and not the binary...

which might make this near impossible to make aroma work like that.. or what do you think??

I have the stock ROM with apps and also CM-11 installed with MultiROM. Is there a way to back up some apps from stock and import them to CM?
[Nexus 7 Original Development] Maxr1998:
backup with Titanium Backup and restore on CM11. Both ROMs use same /sdcard directory and you don't have to transfer something.

[Nexus 7 Original Development] Tasssadar:
New testing build of TWRP for F2FS. It now contains an option to format partitions to F2FS or ext4 directly from recovery, in Advanced->f2fs/ext4 switch (if you're using theme, you need to remove or else you won't see this button). It is very simple because Dees_Troy is working on a "partition manager" for TWRP, so it is kinda pointless to do something great and all if it's gonna get replaced soon.

I also merged with TWRP mainline, which contains fixes for backup failures some users encountered in 2.7.0.0 and some other improvements.

Please, test it and report back, if it goes well, this will be the release version.

[Nexus 7 Original Development] ironmaskusa:
Which build of multirom works with this? I tried v23 and it gave me the same error the last time I tried this with F2FS all ROMs.
[Nexus 7 Original Development] Tasssadar:
Oh, I didn't post it in this thread. Here, use this - v22r. It is newer than v23 despite lower version number: http://tasemnice.eu/multirom-test/multirom-20140421-v22r-grouper.zip
[Nexus 7 Original Development] ironmaskusa:
You are awesome! It works for me, I now have CM 11 M6 and C-Rom.. Both loaded fine and so far so good!

Thanks for not giving up on us that decided to go with F2FS file systems and bringing multirom with a couple more awesome new features! ?
[Nexus 7 Original Development] physwizz:
external

Thanks for this. I haven't used it yet because I'm not at home.

Will it recognise and install roms on an f2fs partition on usb sticks?

Edit: I just tried this, but it doesn't work. It only lets me format the internal to f2fs, not the external.
[Nexus 7 Original Development] physwizz:
Did you format all 3sections (system, cache, data) as f2fs?
[Nexus 7 Original Development] ironmaskusa:
I was already preformatted for all F2FS because I was using CM 11 M6 with mkernel.. Now I m using faux to try out. But yeah, I would go all the way with it to get the best effect even if you are starting anew. This makes my nexus 7 grouper run so sweet.. Plus I can set up a ROM just for gaming purposes, etc.

Good luck! ?
[Nexus 7 Original Development] Tasssadar:
Okay, new recovery. It fixes formatting of /data and adds support for F2FS partitions on flash drives (although I didn't test that one).

[Nexus 7 Original Development] dareino:
AWESOME!....I ran F2FS data only but since MR wasnt working or I couldnt get it to work, I went back to ext4..

Now with this latest ver I am running ALL-F2FS on my two fav roms, Carbon and Liquid Smooth...

Amazing work Tassadar...!

[Nexus 7 Original Development] physwizz:
That's brilliant. Now I'll do some antutu benchmark tests.

Edit: I just installed a ROM on the f2fs partition on a USB stick but multirom 22r still can't see the partition
[Nexus 7 Original Development] Tasssadar:
The kernel in primary ROM must have F2FS support, otherwise MultiROM can't mount the F2FS partition. It doesn't need to be F2FS ROM, the kernel just must have F2FS and it must be enabled. Now that I think about it, if the secondary ROM on USB drive expects F2FS /data and it is ext4, it won't work. So the primary ROM must be F2FS, at least for the time being. This might be fixeable in MultiROM.

EDIT: Here, try it with this MultiROM v24a: http://tasemnice.eu/multirom-test/multirom-20140511-v24a-grouper.zip

Now it should work like this: you need kernel with F2FS support in primary ROM, but the primary ROM can be using ext4 as usual. Then secondary ROMs on f2fs partition on USB drive should work.
[Nexus 7 Original Development] physwizz:
Lego kernel in the primary let me see the f2fs ROM but it won't boot because it doesn't have kexec support. I need to find a kernel with both kexec and f2fs support. Any suggestions?

Edit: I found oxydo #17 works perfectly yaaay

I managed to benchmark both ROMs and got a modest 7.7% performance increase with f2fs.!!!!!
[Nexus 7 Original Development] cyberon:

I would be grateful if you could explain how this works - it is my understanding that it injects your current boot.IMG with the multirom files, right? So if it didn't work, could I just advanced restore -> restore boot.img and all would be working? Thanks in advance.

Bug?

This seems weird. I just updated TWRP with the multirom to 2.7.0 from 2.6.3.0 and it no more installs to FAT32 File Systems! I had installed a ROM before update and it runs flawlessly from Usb but unable to install more.
[Nexus 7 Original Development] physwizz:
You know that you cannot install ext4 backups onto fat32 partitions?
[Nexus 7 Original Development] Agent_fabulous:
Yeah, but...

Yes, but I tried to install the same backups with the older version of the recovery and it worked! Also, I tried to install zip files to it but it continuously fails. However, the old recovery works flawlessly. I will post screenshots if you please in some time. I can't find the old recovery now. (2.6.3.0) :rolleyes:

Hey guys, ive been running into a few problems with my grouper lately. Whenever I download and flash any ROMs or distros, they all fail. They all either say failed to convert or invalid image or whatever. I've used multirom a lot and for a long time now and I've never seen this. I'm running cm11, multiroms kernel, and multiroms twrp. All of which I've uninstalled and reinstalled to attempt a fix. None have worked. My WiFi is fine and uninterrupted so the downloads are fine, they are all the correct images from multiroms xda thread and I've done all of this a dozen times before without issues. What's different guys??? Tell me I'm not crazy lol

I've read through the thread but the question continuily seems to go unanswered how to install ubuntu desktop? I cant find the option in recovery to select "ubuntu" as rom as said in the OP. I know that support/development has stoped but would like to try it myself.
[Nexus 7 Original Development] dadangle:
Its actually easy. I've done it numerous times but for some reason I can't get it now. Download the ubuntu 13.04 image from here, then add ROM and choose Ubuntu installer. Should work for ya. I think I may have messed up my own system

[Nexus 7 Original Development] z31s1g:
You are not using the Holofied theme on your recovery, are you? If you do, remove it and try again.

I've just had a look and found I accidentally removed the option to install ubuntu desktop from the theme. :angel:
[Nexus 7 Original Development] apples723:
I don't think I am. How do I know and remove it?
[Nexus 7 Original Development] z31s1g:
You'd know if you were using it, because the theme needs to be installed manually.

But this brings me back to my first guess. The option that allows to choose ubuntu desktop as a "rom type" only appears if a certain variable in the recovery is set to "true". The variable is set by the Dev when he builds the recovery.

Over at the N7 2013 multirom thread someone was asking the same question you did, because the option isn't available (any longer?) on that device also. Hence the conclusion that it's simply not possible to install linux desktop distros through multirom any longer.
[Nexus 7 Original Development] apples723:
Oh I'm using a nexus 7 2013 I guess I'm in the wrong thread. ?
[Nexus 7 Original Development] dadangle:
Wait wait wait... Is that confirmed? No more linux distros at all?

[Nexus 7 Original Development] z31s1g:
I didn't say that. I just made a conclusion based on observations. Hope Tasssadar will shed some light on this soon...

EDIT

As the option to install Ubuntu desktop is still present on the old Nexus 7, I suppose you don't need to worry.
[Nexus 7 Original Development] Tasssadar:
What are you talking about? It should work as it always did.

Logs or it didn't happen. Or at least names of the ROMs you tried, links to the files or whatever. Or at least make a screenshot of the failed installation screen (vol down+power in recovery, it is the same as android).

Sorry, shoulda known to provide more detail. All I had time to do right now is try the Ubuntu 13.04 that you provided us in this thread and take these screen shots. I honestly don't know where to get the logs for this. I did install carbon ROM last night and it worked fine. I've also installed arch, bodhi and active plasma from http://xdaforums.com/showthread.php?t=2093797 the installations say failed however they would show in the bootloader and would boot.
