Description Corey Marthaler 2011-08-19 22:25:44 UTC

Description of problem:
Every time I extend a volume now I see this warning in the output. Customers aren't going to like to see this. 

[root@hayes-01 ~]# lvextend -l 34 HAYES/linear
  Extending logical volume linear to 136.00 MiB
  Breaking: preferred_count = 1, ix_offset = 1, devices_needed = 1
  Logical volume linear successfully resized

Comment 1 Alasdair Kergon 2011-08-19 23:07:09 UTC

Incorrect error message removed upstream in 2.02.88.

Comment 2 Alasdair Kergon 2011-08-19 23:10:01 UTC

Not present in any released software so this bugzilla does not get mentioned in the technical notes.

Comment 5 Corey Marthaler 2011-09-12 20:00:31 UTC

Fix verified in the latest rpms.
