Hi list,
Im trying to sort some output with lvs using a regex "=~", which results
in an error:
# lvs -o lv_name,lv_tags -S 'lv_tags=~mac1'
dm_report: incompatible comparison type for selection field lv_tags
Otherwise, using the =~ operator on lv_names works well:
# lvs -o lv_name -S 'lv_name=~z'
LV
z1
z2
z3
If I see right, I can use the selection type "string list" here, but no
regex. Is this right? Is there a way to use regex on tags? Im looking
for a way doing
"show me all lv's with tags beginning with "abc.."
TfH!
Oliver

This is not supported yet... but I think we should be able to extend the
functionality here. You can file an upstream report for that if you want
(https://bugzilla.redhat.com/enter_bug.cgi?product=LVM%20and%20device-mapper)
and if there's time/resources, we may add that functionality.
