Description Jonathan Earl Brassow 2012-04-18 16:41:44 EDT
Several bugs that are attributed to mirroring or other LVM components boil down to issues with 'dm_task_run'.  These 'dm_task_run' errors prop-up intermittently and make the bugs difficult to reproduce.  Often, the way to reproduce is loop over a particular operation until /something/ is hit.

This bug is going to be used to encapsulate the various RHEL5 bugs that have popped up due to 'dm_task_run' failures.  The 'dm_task_run' issues should be solved before these other dependent bugs.
Comment 1 Zdenek Kabelac 2012-10-19 04:17:56 EDT
Do we have any  -vvvv traces of failing commands here ?

There should be reasonable good explanation in debug log with the reason of dm_task_run failure.
Comment 2 Nenad Peric 2013-05-23 09:43:33 EDT
The verbose output would be tough to catch through a script, but I will try to do so in the near future. 

In any case the dm_task_run failures are still present and show up very often with mirror failure tests we have.
Comment 3 Jonathan Earl Brassow 2013-05-29 13:44:45 EDT
Note that even though bug 644071 is fixed, there are still 'dm_task_run' failures occurring.
Comment 6 Zdenek Kabelac 2013-09-03 09:15:09 EDT
Please attach normally readable file for this public open BZ.

Comment 20 Peter Rajnoha 2014-02-05 10:32:15 EST
We need the information as requested in comment #14 to move along with the analysis of the problem.... (the customer case attached here)
Comment 22 Peter Rajnoha 2014-04-08 07:04:43 EDT
So, do we have any more debug information here to hook on? Does this happen only on RHEL5 or is it seen on RHEL6/7 as well?
Comment 23 Peter Rajnoha 2014-04-10 05:01:20 EDT
*** Bug 654116 has been marked as a duplicate of this bug. ***
