I recently upgraded our mailserver to 4.4, was on 4.0. It ran for days and days on 4.0 so I'm not dubious about the hardware. The only change has been the addition of raid 5 array to store the mail.. and also some updated packages... The symptoms I'm seeing are that it will run for about a day/ 2days and then users will complain they can't access the mail server. If I try to logon, my ssh session just will go 99% of the way through but just never return me to a prompt. Trying to logon via the console doesn't help either. The common theme I'm seeing here are references to the raid array/controller before it dies.. actually looking at the logs again, it's _not_ moments before the death...

Oct 10 13:19:06 mx1 /kernel.MAIL.0: FreeBSD 4.4-RELEASE-p15 #0: Wed Jul 17 22:19:32 SAST 2002 It's a fairly big ass raid array just for mail and there's another scsi disk for everything else.. /dev/da0s1a 496M 42M 415M 9% / /dev/da0s1f 992M 6.8M 906M 1% /tmp /dev/da0s1g 4.9G 264M 4.3G 6% /usr /dev/da0s1e 992M 55M 858M 6% /var /dev/amrd0s1e 66G 32G 29G 52% /var/mail procfs 4.0K 4.0K 0B 100% /proc So in short.. I'm not too sure what's screwing up and there's probably not much to go on here! Thoughts? thanks, ajt.
