[04:31] <trimeta> I'm having trouble with my LVM-RAID1 setup.
[04:32] <trimeta> I had an existing volume group with one physical volume (which was actually a RAID1 device) and two logical volumes.
[04:32] <trimeta> I just added a second physical volume (also actually a RAID1 device), extended one of my logical volumes to fill the volume group, and grew the filesystem.
[04:33] <trimeta> When booting from a LiveCD, I can see my volume group with no difficulty, mount the logical volumes, etc.
[04:33] <trimeta> However, when booting from the system, I get the following errors:
[04:34] <trimeta> Anyone here, or should I not bother posting the full error?
[04:36] <ScottK> trimeta: This channel is much more active during the European/US business day.
[04:37] <trimeta> ScottK: Fair enough.
[04:37] <trimeta> Do you know much about RAID or LVM, though?
[04:46] <trimeta> In particular, it appears (though I could be entirely wrong here) that for some reason Ubuntu isn't properly initializing one of my RAID1 devices at boot.
[04:49] <ScottK> trimeta: Nope.
[05:22] <trimeta> I'll check in the main channel, there're always people there, at least.

[07:29] <CrummyGummy> Hiya, I'm looking to bond two interfaces together. I've done it in centos like this -> http://tinyurl.com/5du6yu but all the info I've found on the subject for Ubuntu points to installing ifenslave. The Centos way looks cleaner to say the least. Am I correct in this?

[14:40] <zul> ScottK: dendrobates probably would be my guest
[14:40] <zul> s/guest/guess/g
[14:41] <dendrobates> zul: yup
[14:42] <ScottK> dendrobates: (Assuming your the Server Team rep a the release meeting) - Clamav has a new RC out.  They don't go final until 3 Nov, so we're kind of stuck.  Generally their RC -> Final is just security fixes.  So I'd like to discuss uploading the RC and then putting the final in -updates (assuming it all tests well, etc.)
[14:42] <ScottK> If we upload the RC soonish, that gives us a better chance of having any breakage detected and fixed in their final release.
[14:43] <ScottK> I'll be at the meeting for MOTU, so I can discuss.
[14:45] <dendrobates> ScottK: it is late, but I am open to it.
[14:46] <ScottK> dendrobates: It's 0.94 -> 0.94.1 so history says it should be pretty compatible.
[14:46] <ScottK> It's almost all bug fix.
[14:47] <dendrobates> ScottK: We might get some push back.
[14:48] <ScottK> Agreed, so we discuss it and see.

[15:12] <slestak> i have a 8.04.1 server running in a vm as a lamp server.  it is a new install.  mysql5 is running, but i cannot seem to log in (in order to set the root passwd).  mysqladmin -u root dumps usage info instead of putting me into the mysql shell
[15:14] <slestak> i have googled and looked at the ubuntu server guide, but rtfm doesnt seem to be effective for me righ tnow :)
[15:14] <zul> hi mathiaz you were asking about vmbuilder/ec2 last night?
[15:14] <sommer> slestak: you should have been prompted to set the password during the mysql-server install
[15:14] <slestak> maybe the root user doesnt exist yet?
[15:15] <sommer> slestak: you should be able reset it using sudo dpkg-reconfigure mysql-server
[15:15] <slestak> sommer: i dont remember that prompt.  i mustve passed it.  ok, tyvm I will try that.
[15:15] <slestak> i never fully grasped the user and security model of mysql.  i need to study
[15:17] <sommer> you can get pretty fined grained per table per database per user permissions with mysql
[15:20] <slestak> ive found imo, i can get more done faster with postgres, but not all products i want to use support it :)
[15:21] <slestak> is it super important to have a super hard, guarded mysql root password, or is the root user not a su like it is for *nix
[15:22] <sommer> slestak: I think so, there's usually important stuff in the db :)
[15:22] <slestak> sommer: but it is not recommended it be the same pwd as the server right
[15:23] <slestak> is it accepted to be the same as the host server?
[15:24] <sommer> I usually make it different from the server
[15:24] <sommer> doesn'
[15:24] <sommer> t necessarily have to be though
[15:25] <ScottK> dendrobates: I just realized the release meeting starts at the same time I have to pick up a kid from school, so if Server Team gets up before I get there, please just insert a placeholder for clamav so we can come back to it when I get there.
[15:36] <cpu_temp> I`m running ubuntu server. How can I permanently change "ulimit -n". "ulimit -n" gives "1024" and "cat /proc/sys/fs/file-max" gives "65535".  So, what to belive?
[15:38] <henkjan> cpu_temp: /etc/security/limits.conf
[15:38] <cpu_temp> henkjan: wrote "* hard nofile 65535"
[15:39] <cpu_temp> henkjan: I also tryied the sysctl method -> ulimit -n still gives 1024
[15:50] <dendrobates> ScottK: ok
[15:55] <slestak> sommer: i verified mysql is running with ps -ef but the dpkg-reconfigure command we discussed returns nothing and propmts for nothing.
[16:02] <ivoks> slestak: what's the problem?
[16:02] <mathiaz> nijaba: I've filed a bunch of bugs against vmbuilder
[16:03] <mathiaz> nijaba: as a result of yesterday's testing
[16:03] <mathiaz> nijaba: someone should go through them and set an importance and figure out which one should be targeted for intrepid
[16:06] <nijaba> mathiaz: I did see them this morning.  I've still been trying to fix the grub error 2.  I am at the point where, comparing images created with uvb and pvb show NO significant difference in /boot, but one boots and the other does not, so I think I will wait for soren's return on that one
[16:07] <nijaba> mathiaz: I'll be triagging the others, but it seems that you mentioned a couple others that are not in the bug list (such as a problem with --dest), didn't you?
[16:10] <sommer> slestak: sorry, try: sudo dpkg-reconfigure mysql-server-5.0
[16:27] <zul> mathiaz: #284762 -- why?
[16:27] <mathiaz> nijaba: dest -> I've filed a bug

[16:27] <mathiaz> zul: otherwise python-vm-builder has to be depend on python-boto and ec2-ami-tools
[16:28] <mathiaz> zul: which is not really required
[16:28] <mathiaz> zul: in order to be able to run vmbuilder
[16:28] <zul> mathiaz: probably not going to happen for intrepid
[16:28] <mathiaz> zul: well - for intrepid there is nothing for now
[16:28] <mathiaz> zul: so we can pretty much do what we want there
[16:29] <mathiaz> zul: there is also a missing dependency on ec2-ami-tools
[16:29] <mathiaz> zul: the openssl ruby library
[16:29] <mathiaz> zul: I've filed a bug for it
[16:29] <zul> mathiaz: k
[16:30] <zul> sorry about that
[16:33] <zul> yeah the ari/aki options can be renamed
[16:34] <zul> mathiaz: i dont think its a good idea to hard code the aki and ari because that information can change and become out of date

[16:56] <slugg1> hi. i've installed ubuntu server on my old computer. i included openssh during installation, and after installation i've installed openjdk, which didn't work for glassfish so i installed java from sun instead and then glassfish. That's all that's installed. I'm having problems with running glassfish, the start script will run normally - but the glassfish process will die, either instantaneously or after a while. After being up a few day
[16:58] <slugg1> i've altered the $PATH to include glassfish, and $JAVA_HOME to point to the correct java
[16:58] <slugg1> that should include every modification i've done to the system
[17:00] <slugg1> (all actions have been done through ssh)
[17:02] <slugg1> oh, and the system is updated
[17:10] <nijaba> mathiaz: hmmm  good question...  Can't see of any reasons at first sight
[17:32] <CMD_L1N3> hello everyone
[17:32] <CMD_L1N3> I am reinstalling ubuntu-server on my home machine....
[17:33] <CMD_L1N3> while i am back at school my father wants a GUI for it so he doesn't have to do alot in CLI
[17:33] <CMD_L1N3> what would be the best GUI to install?...something like Xfce?
[17:34] <[Solars]> thats a personall preference
[17:35] <CMD_L1N3> well. i want something that is not demanding and will be okay to leave up for a long time
[17:35] <CMD_L1N3> i don't really know  a lot about window managers. i was seeing if anyone else suggests one
[17:37] <[Solars]> try them all, and uninstall the ones you don't want

[19:27] <sergevn> I have a very strange problem, when my server has an uptime for like 3 days ( random) I cannot connect to the machine again, I can open tcp sessions but they dont give the proper replay back.
[19:27] <sergevn> ssh, httpd, smtp, they al dont work anymore
[19:28] <sergevn> someone has some advice or had simmilar problem?
[19:28] <henkjan> check hardware
[19:29] <sergevn> problem is, i dont have physical access atm
[19:29] <sergevn> what hardware could it be? NIC?

[19:41] <daturan> sergevn, when you bring the machine back on line does the syslog show anything interesting? and does using the -v switch on the client when you try to ssh?
[19:51] <sergevn> daturan: by syslog you mean dmesg?
[19:52] <sergevn> daturan: it's not only ssh, it's all the network daemon's :)
[19:52] <daturan> well I would check the /var/log/syslog
[19:53] <daturan> yea I just had a similar issue,,
[19:53] <sergevn> well there doesnt seem to be anything spectacular in syslog
[19:54] <sergevn> ill start with disabling nfs, maybe that's a problem
[19:54] <daturan> yea I would try using verbose when ssh won't connect, at least you'll see what you're not getting,, can you telnet to 22 when ssh and the other services aren't working?
[19:55] <sergevn> yeah, i can telnet, that is the strange thing, alle the tcp! network daemon's dont give a reply back
[19:55] <sergevn> only an empty row :)
[19:56] <daturan> yea, that's weird, I just lost a bunch of .so files so all kinds of services failed
[19:57] <sergevn> the only thing that is left to try
[19:57] <sergevn> is changing the the router where it's behind now
[19:57] <daturan> I did an strace on ssh ,,, that's how I found what was missing,, I don't know how you'd do it for server services
[19:57] <sergevn> but dont think that is problem, because when i reboot the server, everything is fine
[19:58] <daturan> yea,, like you said it does look like it may be a hardware issue,, and dmesg should have shown something,, I dont' really know at this point
[19:58] <sergevn> agree. very frustrating, it's my backup server
[19:58] <sergevn> reboot is ghetto solution but..
[20:00] <daturan> hey it works,, at least till you can replace the hardware
[20:00] <daturan> can you leave a ssh session open? or does the problem cut off existing connections?
[20:01] <sergevn> havent tried that one yet.
[20:01] <sergevn> good one
[20:01] <daturan> yea at least you could poke around, it's tough when you don't have phy access
[20:02] <sergevn> sunday, wtf-problems day
