Subject: raid 5 created with 7 out of 8
Date: Mon, 10 Jan 2005 02:38:37 +0100	[thread overview]
Message-ID: <f4146e7c0501091738200dd32e@mail.gmail.com> (raw)

Hi, I'm trying to set up a raid5 array using 8 ide drives (
/dev/hd[e-l] ) but I'm having a hard time.

I'm using slackware 10, kernel 2.4.26 and madm 1.8.1 (downloading
2.4.28 overnight now)

The problem is mdadm creates the array with 7 of 8 drives up and
running and the last as a spare and does not start recovering with the
spare. And it will not let me remove it and re-add it. Below follows a
script output of the whole thing (less repartitioning the drives and
zero'ing any remaining superblocks)

Any help will be greatly appreciated.
-thanks
