But afterwards: root@ubuntu:~/thin-provisioning-tools# ./cache_check /dev/md1 examining superblock superblock is corrupt bad checksum in superblock So where do I want to go from there? cache_dump doesn't want to play with the superblock because the checksum is bad... do I want cache_repair, then? Do I want to take a backup of anything first? /* Steinar */ -- Homepage: http://www.sesse.net/ -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
