Description Corey Marthaler 2008-02-01 20:46:21 UTC
Description of problem:
This appears similar to verifed bz 385231, but unlike 385231, this doesn't
happen all the time. I saw this while attempting up/down converts with I/O running.

lvconvert -m 1 grant/mirror
  Internal error: Duplicate LV name mirror_mlog detected in grant.
  Failed to create mirror log.

  mirror          grant      -wi-ao 10.00G
  mirror_mimage_1 grant      -wi--- 10.00G
  mirror_mlog     grant      -wi-a-  4.00M

For what ever reason, one of the mimages and mlog weren't properly deleted.

Comment 3 Jonathan Earl Brassow 2008-02-11 21:49:54 UTC
I've been doing looping converts on my cluster for more than a day now - marking
MODIFIED.

Comment 4 Jonathan Earl Brassow 2008-02-15 16:10:32 UTC
apparently, I forgot to actually change the state :(

Comment 5 Corey Marthaler 2008-08-25 16:20:00 UTC
I was unable to reproduce this bug over the weekend with the latest code. Marking verified.

Comment 7 Alasdair Kergon 2010-04-27 15:02:14 UTC
Assuming this VERIFIED fix got released.  Closing.
Reopen if it's not yet resolved.
