I don't know about any interactive alert programs, but I do a manual
"cat /proc/mdstat" periodically to check my software RAID. Results look
like this:
---------------------
[root@Printman root]# cat /proc/mdstat
Personalities : [raid1]
read_ahead 1024 sectors
md0 : active raid1 sdc1[1] sdb1[0]
4160704 blocks [2/2] [UU]
unused devices: <none>
---------------------
You can see by the [UU] that both drives are up.You'll see something
else if a drive has failed or is not running optimally.
