Greetings, (warning: I am a newbie to LVM! I am probably doing something stupid.) Environment: RedHat 8.0 (RH stock 2.4.18-14) lvm-1.0.3-9 Before this machine became quasi-production, I was messing around with LVM and Raid. I probably screwed somethinng up royally and I am hoping that someone could help me reverse it... I have a RAID 5 array of 3 physical hard drives 120G and a hopefull LVM combination of a 40 and 80 to make 120. (I had this working for a few days until a reboot) After my reboot, the lvm component of my raid array failed and I have been degradded mode ever since... So lets try my LVM commands... # pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/md0" is associated to unknown VG "test_vg" (run vgscan) pvscan -- inactive PV "/dev/hdj1" is associated to unknown VG "vg1" (run vgscan) pvscan -- inactive PV "/dev/hdc1" is associated to unknown VG "vg1" (run vgscan) pvscan -- total: 3 [229.29 GB] / in use: 3 [229.29 GB] / in no VG: 0 [0] (I wanted to combine /dev/hdj1 and /dev/hdc1 to built vg1, the problem appears to be why /dev/md0 still thinks it is a part of test_vg?) # vgscan vgscan -- reading all physical volumes (this may take a while...) Segmentation fault # ls /etc/lvmconf/ vg0.conf vg0.conf.2.old vg0.conf.4.old vg1.conf.1.old vg0.conf.1.old vg0.conf.3.old vg1.conf # ls -l /dev/test_vg ls: /dev/test_vg: No such file or directory So I guess the question is how to I get rid of test_vg?? I think once I eliminate test_vg, then my vg1 will behave correctly. Oh, here is my raidtab in case you are interested.. # cat /etc/raidtab raiddev /dev/md0 raid-level 5 nr-raid-disks 4 nr-spare-disks 0 persistent-superblock 1 parity-algorithm left-symmetric chunk-size 128 device /dev/hdf1 raid-disk 0 device /dev/hdh1 raid-disk 1 device /dev/hdl1 raid-disk 2 device /dev/vg1/lvol1 raid-disk 3 TIA, Daryl _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
