Insufficient replicas on RAID-Z2?!

That showed good ZFS labels on each disk partition. I was hoping there was a bad label or two and that was why ZFS did not think it could use that device.

I have had issues with SATA port multipliers (PM), so if the enclosure does use SATA PM I would try in a different enclosure with direct connections between drives and SATA controller ports (or even a SAS controller).

We are in trying odd, corner case fixes here, it might be faster to just restore from backup if you can stand the loss of a few months worth of data, as we might never get this zpool to come back online.

try
zpool import -fFX -R /mnt/ datapool # can run several hours

It’s from another truenas forums thread.

I have the same issue.
What is weird, zpool import shows the pool in good shape.

 pool: data
    id: 7520744140823365409
 state: ONLINE
status: Some supported features are not enabled on the pool.
        (Note that they may be intentionally disabled if the
        'compatibility' property is set.)
action: The pool can be imported using its name or numeric identifier, though
        some features will not be available without an explicit 'zpool upgrade'.
config:

I saw, that a github thread that might be due to the special vdev and he was somewhat able to reproduce that issue.
I just can send the link, as I had to create a new account here. :frowning:

For me it’s the same the zdb -l shows that the disks still have valid zfs pool information…

zpool import -fFX -R /mnt/ datapool helped me importing the pool.
But also I changed from TrueNAS to OpenMediaVault, as it has a newer ZFS code.

25

Could I install OpenMediaVault instead and then import the pool even though it was built on Truenas?

truenas_admin@kemosaaba[~]$ sudo zpool import -fFX -R /mnt/ Taranis
[sudo] password for truenas_admin: 
cannot import 'Taranis': one or more devices is currently unavailable

Crap…
