Hi all,

I'm getting new servers with 6 x 300G SAS on Adaptec AIC-9410, and
finding RHEL5 is the only distro now with aic94xx module. I enabled
RAID function of AIC9410 and set up a RAID 0 array on disk 2~6 to form
an 1.4T logical volumn, leaving disk 1 a stand-alond disk.

During RHEL5 install everything seems okay, I mount disk1(/dev/sda1)
to "/", disk2 to "swap" (4G, /dev/sdb1) and "/home" (1.39T,
/dev/sdb2). But when rebooted the system complained that it cannot
mount /dev/sdb2. In "filesystem repair" mode I tried "mkfs.ext3 -L
/home /dev/sdb2" and it seemed to work since I can login into the
system afterwards.

However, it turned out that it is still in trouble that when I tried
to add a user into Linux, it failed, telling "adduser: cannot create
directory /home/foo". I then tried to make the dir manually, just got
"mkdir: cannot create directory `foo': Read-only file system".

Checked "dmesg", and I got things like:
attempt to access beyond end of device
sda: rw=0, want=2927380230, limit=585937500
printk: 31 messages suppressed.

Is anyone has idea about how to solve this problem? Thank you very much!
