ThinProvisioned lvm's Don't Activate or Mount

Hello All,

I have two PV's with Thin Volumes within them. Im not able to mount or activate either after trying to vgcfgrestore one of them.
PV,VG and LV display/scan all show volumes
but cant activate them or mount them.

I ran the following command to restore the thin volume from the metadata file in /etc/lvm/archive.

vgcfgrestore --force -f /etc/lvm/archive/vg_sfim_00640-658506285.vg vg_sfim Scan commands:

[root@erbium ~]# pvs

  PV         VG        Fmt  Attr PSize  PFree

cant seam to activate them when i do a vgchange.

Get the following output:

[root@erbium ~]# vgchange -ay
Check of pool vg_fmrif/thinpool failed (status:1). Manual repair required! 0 logical volume(s) in volume group "vg_fmrif" now active
Thin pool transaction_id is 649, while expected 647.
0 logical volume(s) in volume group "vg_sfim" now active

Also dmsetup command used to show me the volumes in question, however after reboot it does not

Any help would be greatly appreciated.

Try passing the -K flag with vgchange.

    # vgchange -Kay

You can't "undo" changes to a thin pool like that.

Because of the way the data is stored changes to thin devices generally cannot be reversed.

What change were you trying to revert?
