Low disk space error
Asked by Richard:

I have bumped up my Java memory pool so I have 43% free and healthy but Confluence still returns "Unexpected error see log for details" when I try and upgrade Apps. Looking at log I see the below kind of entries:

2019-06-14 19:31:02,445 INFO \[Catalina-utility-1\] \[com.atlassian.confluence.lifecycle\] init Confluence is ready to serve

As mentioned before, this is my system information Java memory status

Unfamiliar with the diskpart commands but the results don't make sense to me. See image below. I can see the size of disks correspond to whats seen in explorer but the Free column has me befuddled.

Cheers

Richard

body: As log says, there is no left space on your disk.

<br />

However, using the GUI disk seems to have space, so I'm wondering if you have any [disk quota vs user quota](http://serverfault.com/questions/663189/ddg#675927) configured?

Kind regards.

body: Having now read up diskpart and what it's telling me I looked deeper and the quota circa 6GB is down on the threshold 8GB: This I can understand then generating the log entries I'm seeing but with the disk space available I'd expect Confluence to carry on and install the Apps. Surely it doesn't simply say threshold breached and stop trying?

I assumed the log entries related to the App install but maybe there is saying underlying and I'm not seeing it yet as the disk space issue is taking precedent.

Thanks

body: Hello Richard,  

It seems your disk is almost full. Could you check the disk capacity and type the output here?  

On windows:

1.Run cmd  
2.Type "diskpart" ...hit Enter  
3.Type "list disk"....hit Enter

now you can see ur total HDD space in GB.  

On Linux,  
1. run **df -h** command  

Kind Regards.
