Whether the bugzilla is publicly open is unclear to me, atleast there didn't seem to be a link there in sistina.com/lvm - or I didn't find it. Actually I'm not sure if there is a real reason to fix this, as it would need making vgscan understand more about the raid-stuff, but it sure does look confusing. Perhaps a generic facility to "blind out" devices from it? Perhaps this kind of capability should be in the kernel, not just for LVM.. I recently had a problem with a volume group reusing an existing logical volume number, but I resolved that, as vgscan suggested, with vgexport/vgimport. However, this bug appeared: vgscan -- reading all physical volumes (this may take a while...) vgscan -- found active volume group "mirror" vgscan -- found active volume group "ibm9" vgscan -- found active volume group "archive" vgscan -- found inactive volume group "mirrorPV_EXP" vgscan -- ERROR: VG "mirrorPV_EXP" reuses an existing VG number; please vgexport/vgimport that VG or use option -f vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume groups I imagine this is because /dev/md/1 is raid1 and consists of /dev/ide/host0/bus1/target1/lun0/part1 and /dev/ide/host0/bus0/target1/lun0/part1. Output of pvscan: pvscan -- reading all physical volumes (this may take a while...) pvscan -- ACTIVE PV "/dev/md/1" of VG "mirror" [55.91 GB / 13.89 GB free] pvscan -- inactive PV "/dev/ide/host0/bus1/target1/lun0/part1" is in EXPORTED VG "mirror" [55.91 GB / 13.89 GB free] pvscan -- inactive PV "/dev/ide/host0/bus0/target1/lun0/part1" is in EXPORTED VG "mirror" [55.91 GB / 13.89 GB free] pvscan -- total: 6 [311.82 GB] / in use: 5 [290.79 GB] / in no VG: 1 [21.03 GB] (some lines removed) I run kernel 2.4.16 and LVM-tools from today's CVS. Btw, during the original repairing I saw a situation where one of my volume groups (archive) was twice in /proc/lvm/global. That's not healthy, is it? I imagine it had something to do with the fact that after scanning volume group "archive" it failed to scan volume group "mirror" (due to the reuse-problem), and I kept trying different stuff.. -- _____________________________________________________________________ / __// /__ ____ __ Erkki Seppälä\ \ / /_ / // // /\ \/ //ircnet Modeemi Ry\ / /_/ /_/ \___/ /_/\_\@modeemi.fi http://www.modeemi.fi/~flux/ _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
