MP Server / Reclaiming Cache Filesystems...
« on: June 20, 2012, 06:37:40 AM »
Hi everyone...
I have a customer with a large number of cache filesystems. After completing an audit, we've discovered that we can eliminate about half of the data from the cache because it's very rarely accessed.
They tried to use arsmaint to clear out the cache filesystem using 'arsmaint -c', but of course, CMOD wants to keep as much data as possible in the cache to improve retrieval performance, so it's NOT deleting what we want deleted. The -n 0 and -x 0 parameters don't seem to change this behavior when used with the -g option.
I'm wondering if anyone has any clever ideas for forcing data out of the cache filesystems, so that we can reclaim storage space. I've got an idea for a script to perform this, but I just want to make sure I'm not over-thinking the solution...
