Mixing mdadm-1.6 and 1.8.1 for creating/managing the device doesn't
work, it gives me an segfault.
try patching mdadm-1.8.1 with this patch, it might help with the
segfault.
This works! Thanks a lot!
great.
Now creating the md-device with versions prior 1.8.1 works (I tested
1.60 and 1.8.0) - restarting the array with them fails.
With 1.8.1 (with patch applied) I get an 0 Block device created bit I
can restart the (correct) device I created with 1.60.
1.8.1 changed the way devices get created, i did not have any chance to
test it with multipath yet.
see the changelog for more information.
Now of course it would be great to get the device created and restarted
with the same utility. We'd like to use it in production environment
here, can more experienced mdadm users recommend that, these problems
did not really strengthen our confidence in mdadm (at least when it
comes to multipath, we have (of course) been using mdadm successfully
for raid on severall systems).
Are the code changes in 1.8.1 so drastic that you would recommend to
stick with prior versions and fix the issue with starting the array or
1.8.1 is considered a development version, not ready for production.
would you suggest to get 1.8.1 to get MD creation in 1.8.1 fixed (well
it need's to be fixed anyway ;-).
it needs to be fixed.
