Hello all, I have a question that I believe is related to the device-mapper but may easily be lvm2 instead. In any even here goes. For the purposes of this discussion I have two volume groups defined, vg1 and vg2, each with one logical volume (lvol0 for each). When I activate a volume group the logical volume(s) appear under the /dev/mapper directory such as: # vgchange -a y vg2 # ll /dev/mapper total 181 drwxr-xr-x 2 root root 104 Feb 25 09:34 . drwxr-xr-x 35 root root 185472 Feb 25 09:34 .. lrwxrwxrwx 1 root root 16 Feb 16 17:34 control -> ../device-mapper brw------- 1 root root 253, 0 Feb 25 09:34 vg2-lvol0 # And # vgchange -a y vg1 # ll /dev/mapper total 181 drwxr-xr-x 2 root root 136 Feb 28 12:26 . drwxr-xr-x 36 root root 185496 Feb 28 12:26 .. lrwxrwxrwx 1 root root 16 Feb 16 17:34 control -> ../device-mapper brw------- 1 root root 253, 1 Feb 28 12:26 vg1-lvol0 brw------- 1 root root 253, 0 Feb 25 09:46 vg2-lvol0 # So no problems. Now if I deactivate them and reactivate them in a different order I get different minor numbers: # vgchange -a n vg1 0 logical volume(s) in volume group "vg1" now active # vgchange -a n vg2 0 logical volume(s) in volume group "vg2" now active # vgchange -a y vg1 1 logical volume(s) in volume group "vg1" now active # vgchange -a y vg2 1 logical volume(s) in volume group "vg2" now active # !ll ll /dev/mapper total 181 drwxr-xr-x 2 root root 136 Feb 28 12:27 . drwxr-xr-x 36 root root 185496 Feb 28 12:27 .. lrwxrwxrwx 1 root root 16 Feb 16 17:34 control -> ../device-mapper brw------- 1 root root 253, 0 Feb 28 12:27 vg1-lvol0 brw------- 1 root root 253, 1 Feb 28 12:27 vg2-lvol0 # Overall this is ok except in the case of nfs. If I'm exporting these filesystems and the minor numbers change the client gets a 'stale file handle'. Is there anyway to keep the same minor numbers or otherwise a way around this?
