Hello,

I have a volume group with 20 logical volumes. Only the last one of these volumes has a strange problem with dmsetup, shown by these commands and output on the command line:

root@host:/home/linux# /sbin/dmsetup info -c -o name --noheadings /dev/vg/lv20
Device does not exist.
Command failed

root@host:/home/linux# lvdisplay -c /dev/vg/lv20
   /dev/vg/lv20:vg:3:1:-1:0:4194304:512:-1:0:-1:253:19

root@host:/home/linux# mount /dev/vg/lv20 /mnt
root@host:/home/linux# ls /mnt
lost+found data1 data2

That is, dmsetup says "Device does not exist" about a logical volume, though the volume exists and is operating normally. What is the possible problem here?


Hi

Have you tried  strace ?

Are you using this only in singly machine with properly running udev ?
Kernel version, lvm version,  distribution... ?
