Hi,
Some weeks ago I upgraded from 2.6.23 to 2.6.27.4. After a failed hard
drive I realized that re-adding drives to a degraded raid10 no longer
works (it adds the drive as a spare and never starts a resync). Booting
back into the old .23 kernel allowed me to complete and resync the array
as usual. Attached find a test case reliably failing on vanilla 2.6.27.4
with no patches.
I've just been hit with the same problem...
I have a brand new server setup with 2.6.27.4 x86_64 kernel and a mix of
raid0, raid1, raid5 & raid10 partitions like this:
And an extra datapoint.
Booting into 2.6.26.5 triggers an instant resync of the spare disks, so
it means we have a regression between 2.6.26.5 and 2.6.27.4
If no-one have a good suggestion to try, I'll start bisecting tomorrow...
