Pool not visible in WebGui / not exportable

[Florian Mulatz]

Hey Guys,

I'm facing a curious problem actually. Yesterday I replaced a disk in one of our stg-pools on one of our FreeNAS Systems on Desaster-Recovery-Site.

The disk itself (da1 - just wondering why only this disk is not showed with gptid?!) was resilvering normally and actually the pool is available via CLI -->

Code:

[root@b1500cce] /mnt# zpool status mia
  pool: mia
state: ONLINE
  scan: scrub repaired 0 in 1h26m with 0 errors on Thu Nov 24 06:42:25 2016

errors: No known data errors

But exactly that pool named "mia" is not available via webgui. I (of course) already looked around in this board to fix this problem on my own without bothering you guys but nothing posted works for me.

I tried to export the volume via CLI to reimport it via webgui but this does not work.

Code:

[root@b1500cce] /mnt# zpool export mia
cannot export 'mia': pool is busy
[root@b1500cce] /mnt# zpool export -f mia
cannot export 'mia': pool is busy
[root@b1500cce] /mnt#

Please give me some hints what's going on there ...

PS: of course I tried several reboots - after every reboot the pool is showed up normally via CLI but not via WebGUI

PPS: Hardware:
Dell R710 with attached
- Dell PowerVault MD1000 (Ctrl: Dell Ctrl. SAS1068E) -- this is the one which actually makes problems
- Dell PowerVault MD1200 (Ctrl: Dell Ctrl. SAS2008)

Did you follow the steps to replace a failed drive?

To be honest ... no :-O

But actually I've seen - unless the volume is not availabe in WebGUI - for example my iSCSI zvol's still working ?! Curious things are going on.
Of course it should be fixed anyway because I'm not able to recreate zvols/datasets anymore ...

From your response I can gather you replaced it via the shell. To get it back to normal, I guess you will have to forcefully remove the disk from the pool, putting it in a degraded state, then use the steps in the documentation to replace it.

Hey, thx for your answer.

Yes you're right - I've done it via cli. I know it's not supposed to do it like that way but I was in panic :-(

I'm a little bit confused regarding your answer now.
My main problem is not that the pool is not working but it isn't available via the WebGUI (but I'm not an expert - maybe this is really in direct correlation to the "wrong" linked disk?!)

Would be nice if I can get a little bit of more (technical) information on that.

Thx in advance

Hey,

Is it the last way to reinstall FreeNas completely then? Unfortunately it seems that nobody else has any ideas on my strange problem.

Thx in advance for all answers

15 drives in RAIDZ1? Geez, didn't you do some reading before jumping into such a bad idea?

 

[Florian Mulatz]

Hey,

I'm a little bit confused about your answer. I'm not really aware of why exactly this should be a problem? Maybe I've overread some major 'dont's' about that?

Regarding the problem which i was facing initially ... fixed on my own.
IScsi service was locking the pool - thats why I wasn't able to export the pool. Imported in WebGui then and now it looks good again.

That vdev is about 50% wider than any vdev should be and, to make matters worse, it's RAIDZ1, which isn't known for its magnificent reliability.
