Thanks Ivan :)
I found It. add following in /boot/loader.conf
===================
vfs.zfs.arc_max="10244M"
===================
I just thought I would give a shout at this for stable/7 as of last
week. I am not sure if this is just me but I had tried to adjust
zfs_arc_max and found out that it was unadjusted to my value after the
system came back up.
Anyone know if it is adjustable on a system with 1024MB of ram ? Is this
just being auto calculated by some other value ?
Can you confirm that you made the modification in /boot/loader.conf, and that
you used the double-quotes around the value as shown above?
The code in 7-stable regarding this is the same as in 8-stable and 9-current,
so if it is done correctly, it has to change accordingly.
Bye,
Alexander.
Yes,
The sysctl in question on my machine is/was put in loader.conf with the
double quotes.
Every time I have set this before I was trying to set it to a value >=
512M which with the values below must have not been excepted and fell back
to 320M.
If I set this to a value of <= 511M it works fine which leads me to
believe this is limited by some other value listed below ?
dmesg:
real memory = 1072107520 (1022 MB)
avail memory = 1035038720 (987 MB)
loader.conf:
kern.maxusers="512" << Not sure if this has anything to do with it.
vfs.zfs.arc_min="80M"
vfs.zfs.arc_max="512M" << This fails. stays at 335544320.
vm.kmem_size="512M"
vm.kmem_size_max="512M" << Maybe this one.
kern.ipc.semmni="40"
kern.ipc.semmns="300"
kern.maxdsiz="536870912"
kern.maxfiles="16384"
There is points in time where I would like to dedicate 2/3 of ram or more
using ZFS arc_max but somehow I feel like I have limited this by one of
the other values that I had not had the time to look into if they impact
larger values of arc_max being set.
Thank you,
Best regards,,
