On my new 10.3 install I set up 2 drives in raid1 mirror, using software raid in yast. All seems to be working fine except in Kinfocenter>memory swap is shown as not available. Yast shows swap with an "*" beside it. My partitions are set up as follows: primary /dev/md0 /boot extended /dev/md1 /swap /dev/md2 / /dev/md3 /home /dev/md4 /share
I'm not that familiar with tweaking swap and have only set it up in yast>partitioner before with no previous problems. This is my first raid setup so there may be an issue with that, but again, all others partitions are working fine. I tried editing swap in yast to format it again as /swap but it failed with an error code -3004.
Anyone know what this problem may be?
The reason is that suspend/resume from a raid swap partition does not work. You have three options:
1. Do not use a swap partion on raid. This ok, if a crash and a reboot after a failing disk is no problem for you. May be acceptable for Notebooks and desktop systems
2. Remove the resume=/dev/md1 from your kernel option line. Suspend/Resume from does not work. Should be fine for servers.
3. Have two swap partions one without raid for the resume and one with raid for swapping, large enough, that the first one is not really used for swapping (I haven tested this).

Most intersting. Option 3 does both un-mirrored and mirrored. I'm not sure I want to test that one out, but sound plausible. I guess I'm good with putting swap on an un-mirrored partition, as long as it doesn't break the mirrors in the event of one disk failure, (see my post a few minutes ago on this). Seems un-mirrored would be faster anyway, but I want to keep the integrity of the mirrored partitions.
