unRAID xfs cache drive reported to be full when it's not

[sammmm]

Hello,

i have a 1TB cache drive in my unRAID server, which is generally working fine. Unfortunately, since last week i am experiencing errors because of a full cache drive, when there are more than 100GB free. I tried to read myself through the forum, but i can't identify a solution.

Please help me out. Thanks in advance 😀

Where are you seeing those errors?

Unrelated, your system share has files on the array

Earlier this day i had this issue when trying to create a folder on the cache drive using mkdir. After a reboot this seems to be gone.

I now get it when i try to create a folder from Windows 10 on my mainly used share (cache enabled) via samba.

When i try to install a docker container which needs to create a folder on the share, it fails with the message: No space left on device.

 

Oh....

I just tried to create a folder using a Krusader docker directly on the cache drive. That worked.

Now that i think about it, it might also be a share issue

Which share?

[sammmm]

the Datengrab share

oh yeah, just tried to install a docker which needs to create a folder on the share. This time i took /mnt/cache/Datengrab/blah instead of /mnt/user/Datengrab/blah. Worked

Looks like you have 250G Minimum Free for that share.

There used to be a bug where Unraid would take the larger of the Minimum Free Space values for the share and the pool in deciding whether a file would fit on the pool.  These settings should be independent of each other - one applying to the pool and the other to the array but I wonder if that is not how it is being handled.

oh damn, that's it! I just decreased it, and now it seems to work. Me so stupid 😶

Not sure - see my previous post - I personally think this is a bug.

Yeah, i see your point. Thanks to both of you
