When we call swapon from the /etc/rc script we get the following
messages...
Adding /dev/rra0b as swap device
No such device: \c
Now what is this refering to? Certainly the 'b' partition is a
valid swap area? Anyone come up with anything similar?

I thought that there was a garbage character in /etc/rc, but was never able to find one. I guess we'll see if ULTRIX 1.1 does this too. -- Louis A.

Um, er, are you SURE you want to add rra0b as a swap device? :-) (Swapon wants a block device.) I think the error message is just wrong (due to a combination of bugs somewhere). -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 4251) UUCP: seismo!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland

Swapon wants/needs block devices for arguments. (IE, Don't use the raw device.) The "funny" error message is due to a missing argument in a printf. (Something bad like "printf (%s : %s\n", arg1);") Also, if the device is currently being used for swapping, you get the same error message. -Fred

It has been my experience that the messages Adding /dev/rra0b as swap device No such device: \c Usually comes from an improperly declared device for the swap devices in the configuration files. (The first message comes from the swapon command...) aps.

I think that a "no such device" is more probably caused by a missing swap specification in the kernel config file. You might want to add config vmunix blah blah blah swap on blah and ra0 ^^^^^^^ -cliff

[go ahead..do it] > Adding /dev/rra0b as swap device > No such device: \c With 4.2 on an 11/750, you (read I) can only swap on filesystems on the boot controller. I remember something like this when I switched the root filesystem to a new controller. I didn't change fstab except for the / entry.

Well, read fstab(5), and you'll notice, that you also have to enter the names of your other swap devices, not only the root file system; that's just another logical filesystem. You will always have at least *one* swap device, due to configuration of your kernel (look through your config file(s)). And *this* swap cannot be added, since it is already added as a swap device. Therefore, if you try to add /dev/rra0b as a swap device, *and* your config file(s) has the line: config vmunix root on ra0a swap on ra0b /etc/swapon will say: No such device: /dev/ra0b. (or - at least - should say so! and will after the bug-eater) --------- Snail: Dennis Olsson, DIKU, Sigurdsgade 41, DK-2200 Copenhagen N, Denmark. UUCP: ..mcvax!diku!doss +45 1 83 62 57 ext. 13.
