ZFS - Pool no such pool

[balrog76]

Hi,

I have encountered an interesting situation. I have a Freenas box on a remote location. Use it for remote replication backup. Worked like a charm until the other day. Found out something was wrong when I got replication errors on my main server. Tried to access remote server (from now on designated remote). It was up, but its data pool (named mixed) was missing.

GUI was kind of uninformative. Just said:
mixed 0 (error) Error getting available space.

ssh'ed into the box tried for more info. Got a short glimpse of an error message saying something about an update going wrong. Then server did a reboot and I never saw the message again. When it got back up i ssh'ed again and did some digging:

[root@freenasr] ~# zpool import
pool: mixed
id: 2818322502422943038
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.

config:

gptid/c0b47009-71cc-11e5-82b2-0050569a5ef0 ONLINE

Additional devices are known to be part of this pool, though their
exact configuration cannot be determined.

Now thats funny. I ony ever had one pool named "mixed" created from those 3 disks. Now it would appear they think they are members of 2 diffrent pools both named mixed, but with different pool id's.

if I try to import them.
[root@freenasr] ~# zpool import mixed
cannot import 'mixed': more than one matching pool
import by numeric ID instead

ok, I'll try that.

[root@freenasr] ~# zpool import 2818322502422943038
cannot import 'mixed': one or more devices is currently unavailable

hm, ok. what abouit the other id.


[root@freenasr] ~# zpool import 17020534927884097234
cannot import 'mixed': one or more devices is currently unavailable

[root@freenasr] ~# zpool history mixed
cannot open 'mixed': no such pool

All other zfs commands that I could think of did just said "no such pool" for mixed.

Any suggestions are welcome :) I know there is alot of bright minds in here. The pool was just JBOD, and as I said, its a backup for another running system (which is running zraid2). So no data is lost, but I would really like so save the trouble of replicating 9 TB of data across 50mbit vpn connection).

The pool was just JBOD

Do you mean it was 3 disks striped together? If so, and given the apparent failure of one of those disks, the pool is lost.

More System Information would definitely help...

Aslo, what is the output of zdb (In CODE tags)? /Thanks to @jde for this :)

Before anyone is able to help, you are going to have to be a bit more detailed about the config
of the pool. Saying the pool is three JBOD disks is not much help. Also give info on how the pool
is attached to the motherboard, i.e. RAID controller, HBA, AHCI.
Is the instance of FreeNAS on dedicated hardware or is it virtual?
The more time you spend helping those that are able to help you,
the fewer questions will have to be asked and answered.
