Hello, I am running Mandrake 8.1 which installs Linux LVM 0.9. I've read posts that mention that 0.9 is "bad for your health." While I'm not totally sure why or how, it seems to be the case for me as well. I installed the OS and ran find with one IDE HD partition dedicated (/dev/hda9, one VG on one PV) to LVM and two LV's (/usr and /var). Yesterday, I added another partition (/dev/hda7) and added its PEs to the VG. I thhen added the newly added PE's to the /usr LV. Everything was great. Then I rebooted. Upon reboot, I got: [root@cray]# vgscan -v vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d" vgscan -- reading all physical volumes (this may take a while...) vgscan -- scanning for all active volume group(s) first vgscan -- found inactive volume group "vg0" vgscan -- reading data of volume group "vg0" from physical volume(s) vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get data of volume group "vg0" from physical volume(s) vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" creating "/etc/lvmtab" and "/etc/lvmtab.d" [root@cray]# I then tried the vgcfgrestore, which ran sucessfully. Now I get vgscan reporting no volumes. Found a reference on how to fix this (using dd and reading uuids from pv's, then writing them back to the disk). That procedure brings me back to the starting point. It seems the data is there because pvscan reports: [root@cray]# pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/ide0/host0/bus0/target0/lun0/part7" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/ide0/host0/bus0/target0/lun0/part9" is associated to an unknown VG (run vgscan) pvscan -- total 2 [12.02 GB] / in use: 2 [12.02 GB] / in no VG: 0 [0] [root@cray]# One more note of interest: My partitions on disk are out of order. hda7 occupies cylinders 2848-3736 and hda9 occupies cylinders 2168-2847. [root@cray]# fdisk /dev/hda Command (m for help): p Disk /dev/hda: 255 heads, 63 sectors, 3763 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 934 7502323+ b Win95 FAT32 /dev/hda2 935 3736 22507065 5 Extended /dev/hda5 * 935 1874 7550518+ 7 HPFS/NTFS /dev/hda6 1875 2135 2096451 83 Linux /dev/hda7 2848 3736 7140861 8e Linux LVM /dev/hda8 2136 2167 256977 82 Linux swap /dev/hda9 2168 2847 5462037 8e Linux LVM Partition table entries are not in disk order So, can anyone help me? Would recreating the VG and adding the PV's to it restore access to my data? Or would I just blow it all away in the attempt? Thanks for any help! -Ben K kf4wbx@hamsnet.net
