Dumping to a standard swap partition on a RAID set is not supported. > I have not, and a search of the archives only came up with one posting, with > a similar question, but no answer: > > http://marc.theaimsgroup.com/?l=openbsd-misc&m=111763609916743&w=2 > > I'm running -current on i386, and have just successfully implemented RAID > level 1 mirroring.

Dunno if you can use something like: config bsd root on wd0a swap on wd0b dumps on wd0b but that might be sufficient... > But ... adding /dev/raid1b doesn't work -- adding this device > to /etc/fstab seems to be ignored, and "swapctl -a /dev/raid1b" fails with > "file not found." raid1b is an unacceptable keyword for kernel config. Dunno about any of this.... I'd have suggested using 'swapctl -D /dev/wd0b', but I don't believe that'd work for you... > Anyone with a successful swap/dump setup who might be able to point me to > what I'm missing? You should be able to do it, but not to swap on a RAID set... Later... Greg Oster
