Hi all.
We have a DUNIX-3.2d box here on which we have a number of filesystems
with minfree=0%. We have basically set them up with minfree=0, and then
run tunefs to set the optimisation to TIME. However, the kernel keeps
on changing the optimisation back (on the fly) to SPACE thus, eg:
Aug 1 13:10:00 truck vmunix: /servers/http/logs: optimization changed from TIME to SPACE
Aug 1 13:19:16 truck vmunix: /servers/http/cache: optimization changed from TIME to SPACE
Aug 1 22:31:35 truck vmunix: /servers/ftp: optimization changed from TIME to SPACE
How can we supress this behaviour? Is this a kernel configuration thing,
or is there a specific `tunefs' flag we have missed?
The manual page for `tunefs' suggests there can be a three-fold
performance degredation with optimisation set to SPACE, which we aren't
prepared to wear.
The partitions in questions are just UFS's (although they are sitting on
an SW300 RAID Box). They are large parititions that we don't anticipate
will fill up, so we would much rather have TIME than SPACE!
Thanks in advance!
