A customer has a machine with four disks in RAID 10 using the ida(8)

ftp://ftp.jurai.net/users/winter/idacontrol.tar would solve a few of your
problems on 5.x or better but getting it to work on 4.x requires patching
and recompiling.
What kind of patching is required for 4.x? Any ideas or pointers?
Now one disk is broken. I have some questions:
1. How can I detect that a disk in a raid cluster is broken? It seems
natural to me that the raid driver would log info about a broken disk,
but I have not seen this happen with any raid controller driver.
Most array drivers have a userland utility that allows inspection of
array status. The utility for ida(4) isn't in the base system yet.
Oh. A port would be great. :-)
Any ideas on something similar for the ciss(4) controller?
2. The system is extremely slow and hardly usable right now. The
customer are still waiting for a replacement disk. Is there any way to
get the system to just ignore the broken disk instead of trying to use
it and fail. I get thousands of "ida0: soft error" in messages log. If
the system would realize that it had problems with the disk, and ignore
them, perhaps it wouldn't become unsable,
Well, you could rate-limit the error messages, or comment out the message
entirely.
You mean from /etc/syslog? That is not the problem, it seems to be some
kind of timeout for every error that is the problem, I'm not sure. CPU runs
at 100% constantly, anyway, but mostly running postgresql and java, not
syslogd.
3. Will the array rebuild automatically once they insert the new disk?
Depends on the BIOS setting.
OK, thanks.
