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
