Subject: [linux-lvm] UUID
Date: Thu Jan 9 16:34:01 2003 [thread overview]
Message-ID: <1042151798.18166.271.camel@mosix> (raw)
Can someone explain the UUID, etc on a volume and on VGs?
Is the UUID stored on the volume, or on the host machine?
The reason I ask, is that I have a parrallel scsi raid, which is
connected to 2 machines. If i reboot both machines, or go through a
vgexport/import procedure (while online), i can see the VGs and LVs on
both machines.. can even mount the volumes simultaneously (It was only a
test.. I understand that it is not a Shared Filesystem, and would never
do simultaneous mounts on production filesystems).
This is what I believe to be the case:
1. The UUID is stored on the volume itself, and the VG data is stored
somewhere on the disks also.
2. The import/export/activated/deactivated status of a volume is held on
the host machine.
this allows 2 machines to see the same VG/LVs.
Is this correct? And is it supported as a function of LVM, or am I in
'unsupported' territory?
