[linux-lvm] pvmove problem: Inappropriate ioctl for device

[Peter Samek]

Hello.

I have a RedHat 7.3 system with a 2.4.20 kernel and lvm version 1.0.3.

===
[root at noe root]# pvmove --version
pvmove: Logical Volume Manager 1.0.3
Heinz Mauelshagen, Sistina Software  19/02/2002 (IOP 10)
===

The machine has two 80GB disks and there are three RAID arrays.

===
[root at noe root]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/md/1" of VG "mirror" [20 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/md/2" of VG "strip"  [97.65 GB / 2.50 GB free]
pvscan -- ACTIVE   PV "/dev/md/3" of VG "strip"  [13.34 GB / 12.34 GB free]
pvscan -- total: 3 [131.01 GB] / in use: 3 [131.01 GB] / in no VG: 0 [0]
===

/dev/md/1 is a raid1, /dev/md/2 and /dev/md/3 are raid0s.

I'm trying to move all PE from /dev/md/3 to /dev/md/2, so I could remove
/dev/md/3. But "pvmove -v /dev/md/3" spits out this error message:

===

Is there something I am missing or is it a known bug in this version?

Thanks for any help.
