Solaris

seg mentioned using the swap partition for the metadb's.

This way works well, and at a previous place that I worked, all our solaris servers were set up this way.

A reboot is not needed to disable swap. All you need to do is a swap -d, then add the metadb's to the swap partition, then create metadevice/s for the swap partition, then add the metadevice as the swap partion. Update the vfstab file to reflect the fact that swap is now using a metadevice and not a direct partition.

Available swap space will be reduced by the amount of space allocated to the metadb's

many thanks TanDeeJay & Seg, that looks like the way to go. It looks a lot 'cleaner' than pinching space off swap, creating a new partition for metadb's etc etc.

I'll give that a go this week on 2 of our hosts & report back on how I get on.
