Description Corey Marthaler 2006-05-31 18:21:19 UTC 
Description of problem:
I had a cmirror which was 14% done being copied, I then rebooted a node in the
cluster which didn't have any I/O going to that mirror. The mirror copy then
appeared to restart again at 0% and slowly and eventually made it's way to 100%
copied. I thought that the whole point of the log volume was to not have to
re-copy the whole mirror every time a failure happened.

Version-Release number of selected component (if applicable):
[root@taft-04 sbin]# rpm -q cmirror-kernel-smp
cmirror-kernel-smp-2.6.9-4.2
Comment 1 Jonathan Earl Brassow 2006-06-02 21:55:58 UTC 
This was a problem were I was making the complete_resync_work function handle
what should have been in the clear_region function for recovery scenarios.  The
result was that although the clear_region was happening, that bitmap was not
properly being written.

Fix will be in next rev after cmirror-kernel*-2.6.9-4.2.
Comment 2 Corey Marthaler 2006-06-05 23:05:21 UTC 
This appears to be fixed.
Comment 4 Alasdair Kergon 2010-04-27 14:52:13 UTC 
Assuming this VERIFIED fix got released.  Closing.
Reopen if it's not yet resolved.
