Hi,
I think I do something which isn't very clever ...
I needed temporarily some disk-space, so I thought:
Look at your raid, if it works you can take one disk for
a short time (I use raid1).
cat /proc/mdstat looks good, so I hotremove one of two partitions.
When adding the disk again with raidhotadd /dev/md1 /dev/hdb3
it starts to synchronize but it never stops to synchronize...
in messages I found:
---------------
Oct 11 17:54:24 hhbgate kernel: md: trying to hot-add hdb3 to md1 ...
Oct 11 17:54:24 hhbgate kernel: md: bind<hdb3>

Oct 11 17:54:24 hhbgate kernel: md: using maximum available idle IO bandwith (but not more than 200
000 KB/sec) for reconstruction.
Oct 11 17:54:24 hhbgate kernel: md: using 128k window, over a total of 78482304 blocks.

and later, when I am around 60 % of recovering:
Oct 11 18:15:31 hhbgate kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Oct 11 18:15:31 hhbgate kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=97562309,

Oct 11 18:15:32 hhbgate kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=97562309,

and so on with some more sectors and later
Oct 11 18:15:44 hhbgate kernel: end_request: I/O error, dev hda, sector 97562304
Oct 11 18:15:44 hhbgate kernel: raid1: hda: unrecoverable I/O read error for block 94440448

Oct 11 18:15:44 hhbgate kernel: ..<6>md: syncing RAID array md1
the recovering prozess starts again and again.
Any hints what to do?
Thanks
