Making sure you know which are original and which are snapshot, run
on the snapshot ones, then vgchange -u and vgrename.
Use a filter in lvm.conf (env var LVM_SYSTEM_DIR to use different one if
an automated process, not a one-off) or with --config on each command so
the snapshot devices are visible.
I made a copy of /etc/lvm/lvm.conf to /tmp-lvm.conf, changed the filter
line to this:
Filter = [ "a|/dev/sdf|", "a|/dev/sdg|", "a|/dev/sdh|", "a|/dev/sdi|",
(sdf, sdg, sdh, and sdi are all snapshot devices of the vg)
And then I ran "sudo /usr/sbin/pvchange --config /tmp-lvm.conf -u
/dev/sdf1" but I get this error:
Parse error at byte 14 (line 1): unexpected token
Failed to set overridden configuration entries.
Run `pvchange --help' for more information.
Am I maybe using the --config option wrong?
