Out of disk space errors

[itlists]

Hello,

 

I upgraded to Unraid 6.8.0 few weeks ago and its been running smooth until now.

I run two dockers, Transmission_VPN and Plex. Both started saying they're out of disk space. However, none of my disks are full:

Array is 61% full

Cache is 67% full

Boot is 0.01% full

 

Interestingly, df -h shows that cache is 100% full.... strange...

 

Below is the error from Transmission_VPN:

/etc/openvpn/start.sh: line 119: echo: write error: No space left on device

 

Below is the error from Plex:

File "/usr/lib/plexmediaserver/Resources/Python/lib/python2.7/logging/__init__.py", line 845, in flush
self.stream.flush()
IOError: [Errno 28] No space left on device

 

Help is very much appreciated! My nas is currently unable to function normally.

 

Thanks!

You're using a 120GB and a 250 GB in a cache pool.  A know limitation of BTRFS (not technically unRaid) is that it reports the incorrect size.  You actually only have 120GB available.

Hmmm... ok.. however, I've been using unRaid for at least a year and this is the first time this problem has occurred.

Is there a workaround, other than replacing the 120GB with another 250GB?

No workaround.  With a 120 and a 250 set in RAID1 (the default), you by definition only have 120GB available.  You can however change the pool to be JBOD which will give no redundancy, but allow 370GB total usage
