Truenas pool offline. Not able reattach the disks

[kramac]

Hi All,

I setup Truenas system with 2 disks (mirroring) and loaded all my critical data into it. Recently by mistake i removed the disks from the server (deleted the metadata).

Now the pool is offline. I am not able to reattach the disk because it says "Unknown file system LVM2_member" on mount command.

One of the disks has 1 logical volume and other disk is empty (even thought the disks were in mirroring mode).

How do I recover from this situation?

Any help help is appreciated.

Thanks and regards
