[LUGSB] checking a software RAID partition for consistency

[Mikhail Bautin]

Hello Everyone,

What is the best tool to check a software RAID partition on Linux for
consistency?
I know of /proc/mdstat, this is what it gives me:

Personalities : [raid6] [raid5] [raid4]
md0 : active raid5 sdb[0] sdd[2] sdc[1]
      976772992 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]

but is there something like fsck for RAID that actually goes and checks the
disks?
Also, what is the standard monitoring tool for software RAID that would send
me an
email when one of my disks crashes?  Any help is appreciated.

Thanks,
Mikhail
