Configuration: Ultrix 2.0-B on an 8350, 16MB, 2-KDB50's, ethernet controller, tape controller (basically, a full bus.) The kernel was modified to include a packet filter. When we first had DEC install this thing they had it swapping on two partitions. After modifying the kernel (including the packet filter in the ethernet driver) we have been unable to get it to swap on multiple disks. A bit frustrating because the normal 'b' partition was 17MB - definitely not enough with 16MB of memory. Alas, attempts to add extra partitions (say /dev/ra0b) with swapon merely gives me the error message "swapon:/dev/ra0b no such device." After talking with the DEC person who originally installed the OS he said it always does this. So I checked but it doesn't add the partition. So now we are swapping on /dev/ra3g (40MB is much better than 17MB) but I've got three 17MB partitions floating out there going to waste. Any suggestions?

You don't HAVE to swap on partition(s) B of the other drives. You can do other things with those partitions as well, such as putting /tmp on them, or /usr/spool/news (OK, 17MB is a little small for news!). Check out the chpt(8?) command. Do anything you want with them! You can configure the system to swap on any partition of the second (third, etc.) drives if you want. I never could understand the logic of having the second .. Nth drives with that silly little a and b partitions. On to more constructive (?) solutions: ======================================================================== Make sure your conf file says where the swapping is (e.g., ra1b below): config vmunix root on ra0a swap on ra0b and ra1b dumps on ra0b And that your /etc/rc file has: /etc/swapon -a >/dev/console Although you said you do that by hand and get the error message. Check your /etc/fstab file to make sure that it knows these are swap partitions: /dev/ra0b::sw:0:0:ufs:: /dev/ra1b::sw:0:0:ufs:: ======================================================================== That's about all the advice I can think of.

This doesn't seem to be a problem, as long as you know that the /etc/fstab entries duplicated what was configured into the kernal. BTW, I was talking to some people in the Ultrix support group this afternoon and they said that Ultrix 2.2 had been released. They did ask where I was located, so perhaps there is geographical staging going on. Anyway, I asked my local sales rep to quote up a 1.2 -> 2.2 upgrade for me. Of course last week the sales people were denying any knowledge of Ultrix 2.2... 8-)

Too bad there has been no time to attempt the upgrade - 2.0 was built on a ra60, but never placed into production... Anyone done the 2.2 installation yet? -jj
