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 at erbium ~]# pvs
  PV         VG        Fmt  Attr PSize  PFree
  /dev/sda2  vg_erbium lvm2 a--  59.51g    0 
  /dev/sdb   vg_sfim   lvm2 a--  29.80t    0 
  /dev/sdc   vg_sfim   lvm2 a--   6.58t    0 
  /dev/sdd   vg_fmrif  lvm2 a--  36.39t    0

cant seam to activate them when i do a vgchange.

Get the following output:

[root at 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
  3 logical volume(s) in volume group "vg_erbium" now active

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