Description Corey Marthaler 2011-06-09 15:15:48 UTC
This issue exists in RHEL6.1 as well.

+++ This bug was initially created as a clone of Bug #712145 +++

Description of problem:
Currently when a striped mirror leg is failed, lvm replaces it with a non striped leg.

# BEFORE the stripe leg failure

[root@taft-03 ~]# lvs -a -o +devices
  LV                VG           Attr   LSize  Log         Copy%   Devices
  stripe            revolution_9 mwi-a-  1.00G stripe_mlog 100.00  stripe_mimage_0(0),stripe_mimage_1(0)
  [stripe_mimage_0] revolution_9 iwi-ao  1.00G                     /dev/sdc1(0),/dev/sde1(0)
  [stripe_mimage_1] revolution_9 iwi-ao  1.00G                     /dev/sdf1(0),/dev/sdg1(0)
  [stripe_mlog]     revolution_9 lwi-ao  4.00M                     /dev/sdh1(0)

# leg device /dev/sdc is failed

# AFTER the stripe leg replacement

[root@taft-03 ~]# lvs -a -o +devices
