Are there any plans for IBM and Novell to address this in the future with a patch to the kernel and re-use old slots?
It would need to be something that works for all platforms, not just for our virtual disks. The idea is that by using fresh slots you have a better chance to build long chains of adjacent blocks in a single I/O operation. If utilization is low enough, the "moving cursor" is an easy way to do that. With vdisk we're willing to take the overhead of many small I/O operations because the device is already fast enough (especially when your driver can exploit synchronous I/O completion).
Managing multiple swap disks IMHO for each Linux is not an ideal solution.
Am I overlooking something or is it just the extra entries in your fstab and the setup of the disks on VM ? Would your life be easier when CP would do the mkswap for you? I once suggested an enhancement to DEF VDISK ... LIKE <name> where <name> is the a DCSS that has the correct initial layout (because internally the structures are similar). But I think the idea is on the big pile outside behind building 250 in Endicott.
