03:28:45 <tozhu> hello all, Please help me: I want to limit ARC to 16GB, how to configure it? (I need it is alway limited to 16GB, even the machine is rebooted, the limit is still 16GB), how can I set ti. then you very much
03:29:04 <tozhu> I mean I use smartos, not OmniOS
04:43:25 <danmcd> Read up on the zfscache(8) command, which is a SmartOS exclusive.
04:45:08 <danmcd> Oh shoot.  It *is* undocumented due to its experimental nature.

04:52:32 <danmcd> @tozhu the trick is to do it EARLY.  If you're in Triton, see the ticket I pointed at for how you can do it today in Triton for CNs.  (You'll have to use profiles, though, and unless your system is 128GiB the "compute-hvm" one will not help.
04:53:00 <danmcd> If you use absolute values, you will need to use the -l option.
04:53:20 <danmcd>       `zfscache -l $((16 * 1024 * 1024 * 1024)) `
04:53:44 <danmcd> ANd you'll have to do it early in the system's boot for best results (it'll shrink but slowly, if you lower it mid-uptime).
04:54:22 <danmcd> There's a reason it's undocumented and not advertised:  the mid-uptime shrinking scenario is not comprehensively tested.
09:02:13 <tozhu> danmcd: Thank you very much
12:40:33 <gemelen> other way is to add a loader.conf.local, isn't it?
12:41:53 <gemelen> ah, yes, this is what's there
12:43:12 <gemelen> danmcd: https://docs.smartos.org/modifying-boot-files/ looks a bit less scary to share
