are flashing green.
I am pretty new to this so I wanted some advice on how to proceed...
assuming sdb1 is not physically damaged, can I run
raidhotadd /dev/md0 /dev/sdb1 ?
What is a good way to tell if a disk is damaged? And is how do you map
names like sdb1 to the physical disk?
Thanks,

anton, run this command as root:
dd if=/dev/sdb of=/dev/null count=100 bs=1k
this will dump some data out of your scsi
till all the syncing is done before you reboot.
you probably should also make sure your /etc/raidtab reflects the changes you
made for the next time this happens.

by a bad disk, cable, controller, etc.
i generally find that they can be traced to an unclean shutdown, check your
logs.

I will run the scsi utitility on it after hours... but does anyone
I had very bad performance with this card. I tried upgrading the BIOS and
drivers, but in the end I just threw the card out and built a software
raid wich has worked well since then.

I've had this problem. It was due to that disk being damaged. I suggest
you do a scan on that disk with the scsi utility of your controller. If
it reports bad sectors and such, swap the disk, create the linux raid
partition on it and hot swap it in, as described in the HOWTO

do the kernel developers responsible for RAID read this list? I would be
interested in seeing some constructive discussion about the reports of
degraded RAID performance in the 2.4 kernels. It is particularly
disappointing given that SMP appears to be a lot better in 2.4 vs 2.2

Suppose I have a SW RAID5 over 5 disks, 9.1 G each
We are getting to a point where we need more space, but the box has no
more space. So I am wondering how I might go about upgrading the disks to
bigger capacity volumes. Suppose I insert bigger disks one by one and let
the array reconstruct.
in some cases.

Hi list,
I have the following question:
Does linux software RAID have a defined MIB? I seem to have trouble
finding it if it exists ;-(
