Hi,
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.
Why are you mirroring swap? It offers no performance advantages, nor any significant data-protection advantages, unless the data being processed is both SUPER-valuable and very-ephemerial (such as data being collected and processed in real time from sensors in a non-repeatable or expensive-to-repeat experiment, or say, you're processing stock-market feeds, in which case 15 minute downtime = $100,000 fine, and significantly more for each additional 15 minutes of downtime. Other than something like that, or life-and-death situations (in which case, you should be using QNX), mirroring swap is both a needless waste of disk space AND also hurts your system's performance for very very little benefit. If you can, I would split that swap mirror into two separate swap partitions, and use both of them independently.
Anyone know what this problem may be?
Many thanks,
