This should actually be titled, "Help recovering from stupidity ... why not to use GUI administration tools" I recently had a box fail [VRM on the MB] and moved it's drive into another machine running SuSE 9.0. On this drive where separate patitions for boot,root,swap and one partition comprised of a VG (system) containing eight LVs (usr, opt, var, tmp, local, home, mirror, & vmware). Each logical volume contains a JFS filesystem. When I went to view the VG using the LVM tool under YaST, I somehow managed to re-inistalize the VG on the disk partition [read: blew away the existing metadata] ... Lesson ... use the command-line, Luke. Now of course there is data on this disk that I really need (in home, mirror and vmware) and I know that it is still there - I make an image of the disk using EnCase and walked through it. EnCase does not appear to undestand the Linux LVM or the JFS filesystem, so I was unable to put humpty dumpty back together again. Since all I did (irony intended) was re-initialise the VG descriptor and metadata, the LVs and their respective filesystems must still be there [my snoop with EnCase would appear to confirm this hypothesis]. How do I go about finding the beginning of each LV/filesystem and re-creating the former VG metadata ... and before you ask, now I do not have vgcfgbackup file [but I still have the device nodes and the correspnding 'group' file]. Help would be most appreciated. Roy -- Roy Nicholl 283-A Connaught St. Fredericton, NB Canada E3B 2B3 E-mail: RNicholl@NBNet.nb.ca
