Whenever I try to create a LVM (version 2) snapshot of the lvm containing the root fs my machine crashes. I am using SuSE 9.1 (kernel 2.6.5, lvm2-2.00.15, device-mapper-1.00.09), but I also tried a unpatched 2.6.8.1 kernel with the redhat lvm2-2.00.21 and device-mapper-1.00.19 rpms. Same result... I can't create snapshots of the lvm with the root fs, other lvm snapshots are ok. Is this a known lvm2 problem? If it is a kernel issue, are there any patches? Regards Thomas Klaube
