Hello, I just tried the lvm2/dm-snapshot feature and failed miserably... After reading some older postings in this and the s I'm not sure what to do: setup: lvm2-2.0.21 kernel-2.6.8 xfs VG-Size: 4G on Raid-Mirror (/dev/md1) LV-Size: 1G Calling: lvcreate --snapshot --size 100m --name snap /dev/TestMirrorGroup/OnlineVol will block forever. I have to reboot the computer. After that /dev/TestMirrorGroup/snap is there... I froze xfs before (xfs_freeze -f) Any Clue? Is this related to xfs-FS only or do there exist general problems (I read somewhere about problems snapshotting raids...) BTW: Why isn't it possible to create the snapshot on another VG than the original. This would be quite nice becauce in a typical setup it could be an advantate to have the snapshot on a small extra disk, keeping the original data separated from the writes to the snapshot. Any help appreciated, -Gunnar
