I would like to know if there is a canonical way to list the
physical volumes in a volume group, specifically to extract
the uuid for those PVs in a bash script. I am able to do
something along the lines of,
PVS=$(vgdisplay -vv 2>&1 | grep "PV UUID" | awk '{print $3}')
PVUUID=$(pvs -o pv_uuid --noheadings /dev/sdx | awk '{print $1}')
and then look for PVUUID in the list of PVS.
for uuid in $PVS; do
[ "$uuid" != "$PVUUID" ] && continue
...
done
but this relies on the output format of 'vgdisplay -vv' and
I want to be sure that I will always get the expected result.
Thanks,
steeve
