[linux-lvm] ThinProvisioned lvm's Don't Activate or Mount

[Rock]

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:

cant seam to activate them when i do a vgchange.

Get the following output:

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

Try passing the -K flag with vgchange.

# vgchange -Kay

Thin pool transaction_id is 649, while expected 647.

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?
