making auto tunable - filecache_max

HiExperts,

Please advise how to make the tunable "filecache_max" to auto tunable:


# kctune| grep filecache
filecache_max 16336814080 50% Imm (auto disabled)
filecache_min 1633681408 Default Auto


Thanks in adv,

Re: making auto tunable - filecache_max

If you set it to the default, it should be auto:
kctune filecache_max=default

Re: making auto tunable - filecache_max

Hi rveri,

If filecache_min is currently set to default, the following is acceptable:

# kctune filecache_max=Default

# kctune filecache_max=40%

Re: making auto tunable - filecache_max

Just to be clear, you aren't asking for the tunable to be automagically adjusted in response to changing system demands right?

Isn't that what "auto" means?
canauto is "y" for those.

Unless it is only adjusted upon reboots, which seems to defeat some of the "auto".
