Description of problem:
dmraid needs to add the 'handle_errors' argument to mapping tables created for
mirror mappings in order to take advantage of the resynchronization error handling.

Version-Release number of selected component (if applicable):


How reproducible:
Always.

Steps to Reproduce:
1.Check RAID1 mapping table created via "dmraid -tay"
  
Actual results:
Table doesn't contain the handle_errors argument.

Expected results:
Table does contain it.

Comment 2 RHEL Program Management 2007-11-14 04:24:22 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.
Comment 7 Peter Jones 2008-02-06 23:00:11 UTC 
This change completely breaks RAID 1 in 5.2 -- the kernel does not support
handle_errors.
Comment 8 Ian Kent 2008-02-08 18:19:40 UTC 
I can't get information about this this kernel
issue in time so I have to go with reverting the
patch.

Setting the request flags to reflect that.

Comment 10 Heinz Mauelshagen 2008-12-10 18:41:29 UTC 
This has been addressed in 5.3, closing.

The table syntax differs between upstream and RHEL5 kernel because of the differences in error handling processing:

upstream kernel takes handle_errors as a mirror argument
*whereas*
RHEL5 kernel expects block_on_error as a dirty log argument.
