Hi, Recently I rebooted a server running Linux 2.4.22-pre7 with RedHat's LVM 1.0.3 RPM. Once the machine had come up, 2 LVs which had existed previously had simply disappeared, no trace of them. I have run pvscan and lvscan, with and without the -D flag, to no avail, also upgraded to lvm 1.0.4 and tried again, but no joy, 2 LVs are just gone. eg lvscan: lvscan lvscan -- ACTIVE "/dev/Main_VG/var_lv" [500 MB] lvscan -- ACTIVE "/dev/Main_VG/irix_tmp_lv" [1 GB] lvscan -- ACTIVE "/dev/Main_VG/usr_i386_lv" [2.44 GB] lvscan -- ACTIVE "/dev/Main_VG/squid_cache_lv" [900 MB] lvscan -- ACTIVE "/dev/Main_VG/usr_src_lv" [1.17 GB] lvscan -- ACTIVE "/dev/Main_VG/var_tmp_lv" [400 MB] lvscan -- ACTIVE "/dev/Main_VG/var_cdfs_lv" [1.44 GB] lvscan -- ACTIVE "/dev/Main_VG/pgsql_lv" [200 MB] lvscan -- ACTIVE "/dev/Main_VG/mp3_lv" [9.74 GB] lvscan -- ACTIVE "/dev/Main_VG/usr_local_lv" [1.52 GB] lvscan -- ACTIVE "/dev/Main_VG/irix_mips_lv" [1.66 GB] lvscan -- ACTIVE "/dev/Main_VG/www_lv" [472 MB] lvscan -- ACTIVE "/dev/Main_VG/apt_cache_lv" [1.03 GB] lvscan -- ACTIVE "/dev/Main_VG/home_lv" [4.79 GB] lvscan -- ACTIVE "/dev/Main_VG/pics_lv" [2 GB] lvscan -- ACTIVE "/dev/Main_VG/usr_i386_client_lv" [2.50 GB] lvscan -- 16 logical volumes with 31.70 GB total in 1 volume group lvscan -- 16 active logical volumes pvscan: pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- ACTIVE PV "/dev/md1" of VG "Main_VG" [16.36 GB / 0 free] pvscan -- ACTIVE PV "/dev/rd/c0d0p4" of VG "Main_VG" [2.63 GB / 276 MB free] pvscan -- ACTIVE PV "/dev/rd/c0d0p5" of VG "Main_VG" [9.77 GB / 572 MB free] pvscan -- ACTIVE PV "/dev/rd/c0d0p6" of VG "Main_VG" [3.95 GB / 176 MB free] pvscan -- total: 4 [32.72 GB] / in use: 4 [32.72 GB] / in no VG: 0 [0] There is a discrepancy there, lvscan reports 31.70GB, pvscan 32.72 - but i'm assuming this is due to metadata overhead. Where could these LVs have gone to? Its seems I have information on one of the missing LVs in cfgdata backups: [root@hibernia lvmconf]# grep kits * Binary file Main_VG.conf.5.old matches Binary file Main_VG.conf.6.old matches Binary file Main_VG.conf.7.old matches Binary file Main_VG.conf.8.old matches Binary file Main_VG.conf.9.old matches Though, grepping for the name of the other LV (freeware) doesnt show anything. Sadly, the kits LV isnt the important one. :( Is there anyway to try recover these LVs? Eg, how can I use the config backup? (i'm afraid to restore it, as i dont want to kill off LVs created since the old metadata config backup). And is there any way to find the other LV? (there's an NFS client wondering where its /usr/freeware mount is gone :) ). And finally, how the hell did these LVs just dissappear? (and yes, I will be making cfgbackup's before and after lvcreate's from now on. :( ). Is this a known bug? regards, -- Paul Jakma paul@clubi.ie paul@jakma.org Key ID: 64A2FF6A warning: do not ever send email to spam@dishone.st Fortune: Put your best foot forward.
