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 ? -- jhell _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
