Zpool Auto Import Volume Fails - Crash - reboot

[scansterz]

Hi,
I've searched for an answer or help on this issue.
The server had power outage - tried to reboot and zpools acted 'funny' - one not showing up.

When trying to Auto Import Volumes the screen shows bunch of text flying by and the system reboots.

Anyone have this problem? Crash? Reboot?

RaidZ_T1 - This is the one that will not auto import
the T2 pool - does auto import and works fine.

ll disk show up on the list, all spin up and show as healthy.

Advise!

Thanks ahead for any help to this.

You're using ZFS with half the minimum amount of RAM.

yea, I realize that and it has been debated and I've used it for a year and half that way working just fine till now. how ever I do have on order some more ram.
I am adding to the post because I found another thing: (It says it's there but the GUI does not show it) This came up after I ran "zpool import -f -o readonly=on RaidZ_T1"
and "zfs list -r -o name,mount point"
So something weird is going on...

And then the dilemma - after a reboot no pools available.

.

This is one of those things with ZFS. Once it reaches some "magic" size it wont mount due to not enough memory.
Try bringing your system up to the minimum amount of ram recommended and hope the pool isnt damaged.

"It worked before" is not a valid excuse to not meet the minimum requirements.

I can probably load a generator to 150% of its nominal power. It'll probably work for a while, but it's still a bad idea.

Ha! You have just quoted the exact thing we warn against and what will happen when you run with limited memory resources.

The reason the GUI can't see it is because you used the cli to import it. Wait for your memory to show up and cross your fingers that you haven't corrupted your pool.

 

[scansterz]

yea, it's on it's way. [twiddle-thumbs]
