Feature. That's what priority means, after all. Use this one first, then that one, then all these. In SLES7, its a bug because it will not go to lower priority swap (I found out the hard way). I have not tested this in SLES8 or RHEL3. As to different priorities on swap, that doesn't seem to

Re: Adding Swap Space on the Fly

As to different priorities on swap, that doesn't seem to make much practical sense. It would tend to force all your paging to a single device. If you have different speed devices, it allows you to set up a hierarchy. Think solid-state disk, fast 3390 disk, old 3380s as a possible scenario. You

Re: Adding Swap Space on the Fly

So you are saying that the entirety of swap at highest priority was filled and you ran out of swap or what, exactly? With different priorities, at SLES7, we found that Linux would go into a loop and lock out all other tasks after the first swap with highest priority filled. This was at the RC6

Adding Swap Space on the Fly

All the swap space needs to be the same priority. Otherwise, Linux only uses the first swap space. Feature or bug? = Jim Sibley RHCT, Implementor of Linux on zSeries Computer are useless.They can only give answers. Pablo Picasso __ Do you Yahoo!? Yahoo!

Re: Adding Swap Space on the Fly

Feature. If you want to interleave the use of multiple swap files you set the priorites to be the same. If you want to use swap mutliple swap files in some sort of preferred order (e.g. use a VDISK swap first, a swap partition second, a swap file third, etc) you set the priority of each

Adding Swap Space on the Fly

On SLES 8 we added more swap space on the fly by doing the needed mkswap and swapon commands. But it seems that the new swap space isn't being used: usilws80q:~ # swapon -s FilenameTypeSizeUsedPriority /dev/dasda1 partition
