OT: Disk check on Raid1 area

[daniel huhardeaux <daniel.huhardeaux@tootai.com>]

Hi,

I have a production server under woody with software raid1 setup on 3 
IDE disks (partition type is fd). According to mdadm daemon and 
/proc/mdstat, one of them (ide0 which is #3 in raidtab) seems to have 
failure. At first, hda2 stopped (mirror of /boot) and 8 hours after hda3 
(mirror of /). My question is: how to check/know that hda is really dead 
*without* shuting down server (is still in production with the 2 spare 
disks) and knowing that I just have an ssh access on it.

Thanks for any hint
