FreeNAS unexpected and sudden restart

[okynnor]

My bad, I should be more specific in my instructions, this one should be copypaste-able from anywhere in the shell:
grep -i panic /var/db/system/ixdiagnose/ixdiagnose/crash/info*

But anyways, this is your panic string:
Panic String: I/O to pool 'MybooksVolume' appears to be hung on vdev guid 16849957480317237995 at '/dev/gptid/85ec03d5-7af9-11e7-9214-1078d29b61a3'.

For some reason I/O got stuck and FreeNAS rebooted itself. This could be hardware or driver related, I am afraid I can't tell you much more....

before you insightful reply, I decided to take a look at the amount of free space available for this iSCSI mount. I found out that there was only 2GB remaining free. Would you think that no free space is the reason that the I/O get stuck and FreeNAS rebooted itself?

ps1: I have since freed up more space in this particular mount and am monitoring.

ps2: Is there any option to increase the mount size for iScsi mount? Rather than filling using this thread to discuss this topic, how about giving me a link or thread that will help me out?

Thanks!!

I've noticed that the restarts are still occurring. One thing I noticed is that the connection/Storage repository in iSCSI has not been working as it should. I noticed that in FreeNAS, under "Authorized Access" secret, the secret has been lost and when I try to retype it, it won't save. Is there a reason for this? I think this maybe the problem because XCP-NG is reporting that can't connect to iSCSI. I suspect that this is the root of the problem.

Well yes, unless you did something to resolve the issue it's not going to magically disappear.

I don't have any experience with ISCSI on FreeNAS maybe someone else can shine in.
