My Freenas-based fileserver stopped serving the other day. I couldn't get into it with the browser nor with the serial port, and didn't have ssh enabled, so I had to reboot it (as far as I know, anyway).
When it came back up, I saw this via dmesg:
Dec 4 15:21:03 freenas kernel: pid 2190 (lighttpd), uid 80 inumber 5228 on /var: filesystem full
I double-checked:
freenas# df -h /var
Filesystem Size Used Avail Capacity Mounted on
/dev/md2 75M 72M -3.0M 104% /var
It turns out that /var/db/collectd/rrd/localhost/df filled up with files like df-*.rrd.
I was using FreeNAS-8.0.1-BETA2-amd64 at the time, so I took the opportunity to update to FreeNAS-8.0.2-RELEASE-amd64 and now /var is mostly empty.
After upgrading, I found this bug report (I did look before upgrading):
Ticket #462 (closed defect: fixed) "/var is filled up with /var/db/collectd/rrd/localhost/df/*rrd files" (https://support.freenas.org/ticket/462)
The ticket suggests deleting all the *rrd files to recover. Is that recommended?
Also, should I be periodically checking the size of /var just in case it fills up again?
The comments on that report seem to imply that there was a bug related to this issue and that it was fixed with an updated /etc/rc.d/ix-collectd file.
Did the fix make it into FreeNAS-8.0.2-RELEASE?
