Hi,
I am thinking of setting up a raid 1 type machine. I have a question in relation to disk failure. If software mirroring is used, is there any alerts to the admin about a failed disk ? Or is it up to the admin to detect a failed disk ?
Any help greatly appreciated

an email to admin triggered by change of RAID state would be a good idea I think - why don't you request it at the wishlist:
http://www.e-smith.org/bboard/list.php?f=4
you can alway monitor the status of your RAID setup by taking a peak at
/proc/mdstat with your favourite editor
It gives output like:
Personalities : [raid1]
read_ahead 1024 sectors
md2 : active raid1 hdc1[1] hda1[0] 264960 blocks [2/2] [UU]
md0 : active raid1 hdc5[1] hda5[0] 15936 blocks [2/2] [UU]
md1 : active raid1 hdc6[1] hda6[0] 19269824 blocks [2/2] [UU]
unused devices:
-
....or just at a terminal (telnet) cat /proc/mdstat
it's quite interesting when you first start the array, it takes a couple of hours to sync itself.
