Swapcache comes to Avalon's rescue
This is a fun little side story. Avalon's got ~37G worth of release
related files on it and can't cache the mess in ram so demand is
causing its one hard drive to become fully saturated. This in turn
is having an unfortunate effect on even people doing incremental
However, not to fear, I came up with a GRAND solution! Resurrect
the second drive that had been decomissioned due to a minor media
error and use it as swap space. I've set it up as a 32G swap partition
and used the magic of our swapcache facility to unload the primary
disk a bit by telling the system to swapcache filesystem metadata
plus the 2.8.2 ISOs and IMGs. That appears to have done a fairly
good job offloading the primary drive.
So it looks like swapcache is useful even using HDs instead of SSDs
as a means of managing disk load without necessarily having to resort
to striping the primary filesystem.
