Hi, I recently updated from linux 2.4.6 to 2.4.13-ac8, from LVM 0.9something to 1.0.1rc4. I am using debian, so I grabbed the two packages - lvm10 and lvm-common. Something must be wrong though, cause I can't mount my LVM anymore. This is what happens : Vault:~# mount /glftpd/site mount: /dev/site_vg/lvol1 is not a valid block device Vault:~# pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/hda8" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/hdb1" is associated to an unknown VG (run vgscan) pvscan -- total: 2 [71.35 GB] / in use: 2 [71.35 GB] / in no VG: 0 [0] Vault:~# vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group Vault:~# vgcfgrestore -n site_vg /dev/hdb1 vgcfgrestore -- ERROR: different structure size stored in "/etc/lvmconf/site_vg.conf" than expected in file vg_cfgrestore.c [line 139] vgcfgrestore -- ERROR "vg_cfgrestore(): read" restoring volume group "site_vg" Vault:~# vgchange -ay vgchange -- no volume groups found What's the matter ? Is it a problem that can be fixed by uuid_fixer ? Thanks in advance, Klaus
