/var/db/system 100%

[psoni]

Hello,

We are seeing /var/db/system path full.

System is running Build 11.1-U7
However, when I got to /var/db/system/configs-f1ae6c68bbe041c7bb38cadeec088781, it only shows 11.0-U4
Why is it not showing the current build?

FreeNAS-11.0-U4 directory contains db backup files. I deleted old db files and after that the utilization dropped to 15% (see below)
var/db/system
Size 5.1M
Used 796K

However, just after a few minutes, it reached 100% and I noticed that the size of /var/db/system changed from 5.1M to 796K

How can I fix this and recover space?

Please supply the output of zfs list -t all -r freenas which will show us a better idea of snapshot usage.

You pool is completely full, all 21TBs of space. Your /var/db/... is pretty tiny, the cause is your pool data.

By the way, it's a bit un-common to use the main pool's dataset for all data, (/mnt/freenas). It is more normal to have several datasets below the pool dataset for different uses. Like separating backups from media.
