Description Mimmus 2007-10-09 14:49:32 UTC
Description of problem:
Just after a reboot, this is the output of "multipath -ll":
mpath9 (360060160eb24170010eb64e5104adb11)
[size=70 GB][features="1 queue_if_no_path"][hwhandler="1 emc"]

If I run "multipath -v2", I get:
 remove: mpath9 (dup of mpath1)
 mpath9: map in use
 remove: mpath13 (dup of mpath2)
 mpath13: map in use
(attached larger output of "multipath -v3")

Problem is with volume groups "vg_58" and "vg_62"

multipath.conf

Default config file except for blacklist, where I put EMC controller wwid

Comment 4 Mimmus 2007-10-12 12:47:28 UTC
Still no chance to get this working.
Only using "user_friendly_names no" seems to solve the problem.

Comment 5 Ben Marzinski 2007-10-12 18:16:11 UTC
Can you please post your /var/lib/multipath/bindings file.  This is the file that
maps the WWIDs onto user_friendly_names.

Comment 6 Ben Marzinski 2007-10-26 22:35:46 UTC
Without any more information, I'm going to assume that this the same problem as
bz #320151.  If This is incorrect, please reopen the bug.
