Please help:
Today I removed a defective hdd out of a RAID1-array and swapped in a
new hdd instead.
3 arrays, to be true, md[012]
0 and 1 synced fine, in the process of syncing md2 the old sda threw
errors (in sda4):
md/raid1:md2: sda: unrecoverable I/O read error for block 643686144
md: md2: recovery done.
[...]
md/raid1:md2: sda: unrecoverable I/O read error for block 643686272
----
Did the system stop syncing or is "recovery done" the indication that
md2 was fully recovered BEFORE the system threw sda4 out of the array??
I hope for the second!

The system seems to work OK, md2 which is a PV in a LVM-volumegroup is
there, etc
I just wonder if should somehow re-add sda4 or not touch a thing until I
have a new hdd at hand??
Can/should I somehow test the integrity of md2?
Pls help me to relax in this case ...
btw:
Linux version 2.6.36-gentoo-r5

Thanks in advance, Stefan!
