Storage pool full

[rwfitzy]

I let the storage pool become full on my fully updated FreeNAS (11.2-U5) server in my lab. I have searched and tried many solutions including an attempt to echo > file/to/delete and dd seen below, but no success...

Code:

dd if=/dev/null of=server.leasing2.local-230EE579-71A5-4F52-8AED-1A93E800E46A-43C9FFCF-BACD-42EE-86B3-690C761F6E85A.tibx
dd: server.leasing2.local-230EE579-71A5-4F52-8AED-1A93E800E46A-43C9FFCF-BACD-42EE-86B3-690C761F6E85A.tibx: No space left on device

Guess this means I am going to lose this pool and have to rebuild? Luckily it is only 5TB and offloading now. There are several iSCSI devices and many snapshots.

Try cat /dev/null > /file/to/delete to truncate rather than dd.

Do you have any snapshots existing on the pool? zfs list -t snapshot

Yeah, I tried that one too.

Code:

root@nas:/mnt/Backup/backup/Leasing2 # cat /dev/null > server.leasing2.local-230EE579-71A5-4F52-8AED-1A93E800E46A-43C9FFCF-BACD-42EE-86B3-690C761F6E85A.tibx
server.leasing2.local-230EE579-71A5-4F52-8AED-1A93E800E46A-43C9FFCF-BACD-42EE-86B3-690C761F6E85A.tibx: No space left on device.

And yes, there are lots of snapshots. When I try this to destroy one, the server crashes and restarts...

Code:

zfs list -H -t snapshot -o name -S creation -r Backup/backup@auto-20190515.1245-1y | tail -10 | xargs -n 1 zfs  destroy
