[linux-lvm] lvcreate -- couldn't read physical volume "/dev/md3" (on raid 5)



Hi everyone,

I tried to create a logical volume specifying the "VolumegroupName" and the "PhysicalVolumepath" as follow and it failled.

[root Mamouth proc]# lvcreate  --size 4g -n LogVol00_test -r 1024  Volume00 /dev/md3
lvcreate -- couldn't read physical volume "/dev/md3"


I repeated the same command without the "PhysicalVolumePath" and it worked fine.

[root Mamouth proc]# lvcreate  --size 4g -n LogVol00_test -r 1024  Volume00
lvcreate -- doing automatic backup of "Volume00"
lvcreate -- logical volume "/dev/Volume00/LogVol00_test" successfully created


Can someone explain this to me. "/dev/md3" is a raid 5.

Thanks,

Jean Aumont

PS. You can find in attachment the same command in "Debug mode"
       It also does not work !!!
