Re: [Linux-cluster] (?) Problem with relocating extents within a VG



I don't know if this helps.
I've done some tests on RHEL with pvmove and it didn't work for me
without VG deactivation, so you might go for vgchange -a n <vg>
and run pvmove afterwards.

Two HP DL360 servers, each connected to the SAN via two FC adapters, SAN

I have a volume group made up of two LUNs from our SAN.  I was
attempting to move the extents of one logical volume in the VG from one
PV to another when I received the following error:

[root cobalt ~]# pvmove --name old_coeusdev_data /dev/dm-10 /dev/dm-11
   Error locking on node cobalt.utmem.edu: Resource temporarily unavailable
   Failed to activate old_coeusdev_data

For now, an LV stays where it is located (i.e. on a specific PV) once it
is created.  I really need to move all of the LVs off of that PV so I
can release it from the VG (alphabet soup!).  That PV is part of a
storage pool we need to upgrade to larger drives.

Anyway, any thoughts on this, or other information needed?
