ZFS Disk FULL

[Ronaldosp]

Hello Guys,

scenario:
FreeNAS 8.3.1
vol04 is a raidz1-0 with 3 disks
Iscsi + File Extent VM running on Xen Server

We have a serious problem caused by misuse of a customer who ended up filling our volume.

As follows:

Code:

[root@freenas] /# zfs list -o space
NAME  AVAIL  USED  USEDSNAP  USEDDS  USEDREFRESERV  USEDCHILD
vol01  372G  1.41T        0  1.41T              0      97.7M
vol02  836G  976G        0    976G              0      104M
vol03  77.4G  830G        0    830G              0      33.0M
vol04      0  907G        0    907G              0      15.1M
[root@freenas] /# zfs list -o reservation,refreservation vol04
RESERV  REFRESERV
  none      none
[root@freenas] /# zfs list -t snapshot
no datasets available
[root@freenas] /# zfs list -o name,quota,refquota,reservation,refreservation
NAME  QUOTA  REFQUOTA  RESERV  REFRESERV
vol01  none      none    none      none
vol02  none      none    none      none
vol03  none      none    none      none
vol04  none      none    none      none

Is there anything we can do in this case? Any idea?

We are thinking of trying to do an rsync with full volume to another disk Freenas with a larger volume, is this possible?

Thank you,
Ronaldo

One post is enough, don't you think?

Sorry, inexperience by putting just 2 posts, I'll see if I can delete one of them. :(

Well, now the post with the answer is gone..

Sorry Warri, i don't understood.

You might be able to recover by zeroing one or more files with echo like explained here. Rsync should theoretically work as well. Next time use quotas ;)

Now i understood, lol ...

Well, with relation to the echo, this is not possible in my case because we use File Extent, has only one file with 907g / mnt/vol04/file04.

How to rsync, we are providing the new FreeNAS, if everything goes right place here for everyone :)

Thx

ZFS pools really doesn't like being filled up.. Performance decreases and potential issues like this.. I'm thinking im going to stop at 10-15% free space for media drives..
