Hi, i have a /-filesystem residing on a lv. I also had a snapshot of that lv because I tried some software. After testing the software I merged the snapshot into the origin, by rebooting. It seemed to went fine. Btw: how do I know when merging is finished ? Where can I see results from the merging ? But in /var/log/messages I have error messages about a block device: Oct 14 16:22:45 vm59093-4 kernel: [ 7.580247] Buffer I/O error on device dm-3, logical block 0 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580254] Buffer I/O error on device dm-3, logical block 1 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580258] Buffer I/O error on device dm-3, logical block 2 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580261] Buffer I/O error on device dm-3, logical block 3 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580264] Buffer I/O error on device dm-3, logical block 0 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580271] Buffer I/O error on device dm-3, logical block 9961471 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580274] Buffer I/O error on device dm-3, logical block 9961471 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580341] Buffer I/O error on device dm-3, logical block 0 Oct 14 16:22:45 vm59093-4 kernel: [ 7.580345] Buffer I/O error on device dm-3, logical block 1 Dm-3 is the snapshot I merged (although I named it root-snapshot while creating, not root--snapshot !): Dmsetup info says: ...

The errors appeared during the reboot. Is that normal ?
