I had a LV of 2 partitions on 9.2. No problem. I wanted to be able to access this LV from 9.0. (same system). In 9.0 the physical volumes were detected as belonging to the correct VG. I added the 2 physical volumes in the physical volumes side, then on the logical volume side tried to add it. Told it not to format and where to mount it. Then hit apply. It said it coud not mount it. So I reboot the 9.2 system and now it can't mount it either. Is my data still intack? On the 9.2 system: harley:/home/markh # vgscan Reading all physical volumes. This may take a while... Found volume group "mpx" using metadata type lvm1 harley:/home/markh # pvscan PV /dev/hda7 VG mpx lvm1 [20.00 GB / 0 free] PV /dev/hda11 VG mpx lvm1 [31.55 GB / 52.00 MB free] Total: 2 [51.55 GB] / in use: 2 [51.55 GB] / in no VG: 0 [0 ] Is the above telling me I have 52GB free? I did no format. harley:/home/markh # lvscan ACTIVE '/dev/mpx/mpx' [51.50 GB] normal When I manually try to mount it: harley:/home/markh # mount /mpx mount: wrong fs type, bad option, bad superblock on /dev/mpx/mpx, or too many mounted file systems This message shows up in /var/log/messages: kernel: VFS: Can't find ext3 filesystem on dev dm-0 My fstab entries that used to work: /dev/mpx/mpx /mpx ext3 defaults 1 2 What has happened? Thanks Mark
