The VG is seen, but not the one LV in there kernel: 2.6.14 LVM version: 2.01.04 (2005-02-09) Library version: 1.01.00-ioctl (2005-01-17) Driver version: 4.4.0 My PV for /dev/dshelf3 is /dev/md5 The VG is found, but not the LV within it, apparently because LVM selects /dev/sda1 instead of /dev/md5. Sure enough, that drive is part of the raid set: gargamel:~# cat /proc/mdstat | grep sda1 md5 : active raid5 sdg1[6] sdf1[5] sde1[4] sdd1[3] sdc1[2] sdb1[1] sda1[0] vgdisplay -vv (abbridged) gives: /dev/sda1: lvm1 label detected /dev/md2: lvm1 label detected /dev/md4: lvm2 label detected /dev/md5: lvm1 label detected Duplicate PV 9O6xt9OyES075HwBQHdtmGRb7vD4EOy8 on /dev/sda1 - using md /dev/md5 /dev/sdt1: lvm2 label detected Ignoring duplicate PV ROSSavso6qtpjO7fw93bO7cMntbJ09xz on /dev/sdt1 - using md /dev/md4 /dev/sdh3: lvm1 label detected Ignoring duplicate PV LpvPCRIdjGlQuX4FCWWArPhv7Vv3Cv08 on /dev/sdh3 - using md /dev/md2 /dev/sdl3: lvm1 label detected Ignoring duplicate PV LpvPCRIdjGlQuX4FCWWArPhv7Vv3Cv08 on /dev/sdl3 - using md /dev/md2 Found /dev/sda1 in VG dshelf3 Unlocking /var/lock/lvm/V_dshelf3 --- Volume group --- VG Name dshelf3 System ID gargamel.svh.merlins.org1013790828 Format lvm1 VG Access read/write VG Status resizable MAX LV 255 Cur LV 0 Open LV 0 Max PV 255 Cur PV 1 Act PV 1 VG Size 410.06 GB PE Size 64.00 MB Total PE 6561 Alloc PE / Size 6400 / 400.00 GB Free PE / Size 161 / 10.06 GB VG UUID 6j8wL4-3n1y-WHL3-HM61-IyuS-6vJW-pubTQo --- Physical volumes --- PV Name /dev/sda1 PV UUID 9O6xt9-OyES-075H-wBQH-dtmG-Rb7v-D4EOy8 PV Status allocatable Total PE / Free PE 6561 / 161 gargamel:~# vgchange -a y dshelf3 0 logical volume(s) in volume group "dshelf3" now active Can I help LVM2 find the LV in there somehow? BTW, note that LVM2 did say "using md /dev/md5 (instead of /dev/sda1) and still showed /dev/sda1 as a PV for dshelf3 instead Thanks Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
