HELP !!! CRITICAL: The volume datastore (ZFS) state is UNKNOWN:

dan101aba · Sep 16, 2018

Hi,
I need your help to understand how to restore my files from zfs missing device error,
I have the freenas load from USB version 9.3 with
3 SATA 4T (WD)
1 SSD 250gg
Since I got a Unretryable error on boot I try to reinstall a new version on USB, but my mistake I did it on the SSD drive.
After I did install on USB and upload my config files I got below error.
CRITICAL: The volume datastore (ZFS) state is UNKNOWN
Not sure what was my ZFS configuration and if the SSD(may be cache ) was part of the pool.
I would like to know if there is an option to restore the files from the 3 STATA disks?
See below some command I run to bring up the pool
pool: datastore
id: 3130324954855864268
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.

Protip #1 When installing FreeNAS, disconnect your data drives to avoid overwriting data.
Ok so you had a RAIDz1 and destroyed one disk. You SHOULD be ok. Install the latest BETA as it has better support for importing damaged pools. (See Protip #1)
Once you have a running version of FreeNAS 11.2 BETA3, you should be able to import your pool. If it offers to "upgrade" your pool, dont. Just import it. If the pool still does not show up in the GUI after a successful import, reboot.
If the pool is showing up in the GUI, follow the user guide for the beta to replace a failed drive. If you are unsure or anything is not 100% clear, STOP and ask. Any mis steps at this point and you data is lost.
Protip #2 Always keep backups separate from your main storage.
After the new/old drive is installed and your pool is done with the scrub, install a non-beta version of FreeNAS like 11.1-U4.
Protip #3 Dont run Beta software unless you can debug issues on your own or don't care if your data is lost. ;)

Thanks for the help, I did FreeNAS 11.2 beta 3 installs, and also replace SSD with SATA 2T, and try run import from UI (without success no datastore pool listed) also failed from the command line
Please let me know if you have another idea how to resolve it?

@dan101aba Use the code tages as requested.
Have you tried zpool import -F? Do you recall how the array was laid out? If it was a RAIDz1 and you have insufficient replicas, that means at least two disk are missing from the vdev. Did they fail? were you trying to replace old disks with larger ones? Did you throw the server on the ground? Tell us what happened.

Chris Moore · Sep 17, 2018

This is made more difficult to read because it is not in code tags, which affects the way the text aligns:

Code:

root@freenas[~]# zpool import					  
   pool: datastore
	 id: 3130324954855864268
  state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
   see: http://illumos.org/msg/ZFS-8000-EY
config:

	datastore									   UNAVAIL  insufficient replicas
	  3359151836782873844						   UNAVAIL  cannot open
	  raidz1-1									  ONLINE
		gptid/54f3c43f-efd7-11e3-989a-e03f49ac0a05  ONLINE
		gptid/55be4974-efd7-11e3-989a-e03f49ac0a05  ONLINE
		gptid/568b922e-efd7-11e3-989a-e03f49ac0a05  ONLINE
root@freenas[~]# zpool import -f datastore
cannot import 'datastore': no such pool or dataset
	Destroy and re-create the pool from
	a backup source.
root@freenas[~]#

Now that it is properly displayed, you can see that the missing drive was a single disk vdev that is now missing. You must find that missing disk or this pool is destroyed. There is no recovery from this. The pool was not properly constructed.

The pool was not properly constructed.

Good catch ;).

garm · Sep 17, 2018

Well based on the information given you destroyed the SSD that was part of the pool as a single drive vdev by installing FreeNAS on it. By doing that you made the pool unrecoverable, you need to rebuild your pool properly and restore from backup. Also, please use code tags..
