Greetings,
If this is documented somewhere feel free to tell me where it is:
I just setup a software RAID 1 using 2 IDE disks and no spares. I'm
using the kernel that comes with the RH beta (md 0.90.0, raidtools 0.90).
Anyway to test it, I halted the machine then disconnected one of the
drives. Booted the machine, it goes into degraded mode. Everything fine.
Power down. Reconnect drive. Restart. The array still stays in degraded mode :(
(timecounter was out by 2).
Looking at the source this is the intended behaviour if the md devices
are out of sync by more than one time increment. I managed to then find the
command raidhotadd, and was thus able to add the extra partitions back into
the array (I am using 5 md devices) manually, and everything was peachy again.
Only problem was that it was ugly having to specify each of the
individual partitions/md devices.
Question: Without having spare disks is there a way to get md to
automatically start a reconstruction using the "freshest" copy? (besides
getting rid of the test in the source). Is there a reason why it should not
do this?
Thanks.
