I am trying to run thin dump on the snapshot of lvm thin pool metadata. The commands used to generate the snapshot and take the thin dump output are: dmsetup message /dev/mapper/VG-POOL-tpool 0 reserve_metadata_snap block_no=`dmsetup status /dev/mapper/VG-POOL-tpool | cut -f 7 -d " "` thin_dump -f xml /dev/mapper/VG-POOL_tmeta -m $block_no dmsetup message /dev/mapper/VG-POOL-tpool 0 release_metadata_snap While creating the snapshot I am dumping data to the thin volume. The error message I get is: "metadata contains errors (run thin_check for details). perhaps you wanted to run with --repair" Is there something wrong with the way I am using the commands ?
