I create a vg1 on one SSD and create a lv1 in vg1.
Then I run:
sudo thin_check /dev/mapper/vg1-lv1
It shows:
examining superblock
superblock is corrupt
bad checksum in superblock
Can someone teach me how to fix corrupted superblock?
Hi, thin_check should be run against the metadata device (more
precisely, against a snapshot of the metadata device).
I suggest you reading thin_check/thin_dump man pages:
