Hey all!
Just chipping in a 'mee to' here, the sysctls I posted earlier[*] haven´t been a complete cure, but slowing the process down a bit, just for reference. Still having systems becoming unresponsive after different periods of time, depending on load, I guess.
I wonder though, if UMA isn´t used by ZFS by default:

Just chipping in a 'mee to' here, the sysctls I posted earlier[*] haven´t been a complete cure, but slowing the process down a bit, just for reference. Still having systems becoming unresponsive after different periods of time, depending on load, I guess.
I wonder though, if UMA isn´t used by ZFS by default:
# sysctl vfs.zfs.zio.use_uma
Code:
vfs.zfs.zio.use_uma: 0
What does this mean, in context?
# vmstat -z
Code:
ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP
UMA Kegs: 208, 0, 104, 15, 104, 0, 0
UMA Zones: 1408, 0, 104, 0, 104, 0, 0
UMA Slabs: 568, 0, 379499, 147006,985852809, 0, 0
UMA RCntSlabs: 568, 0, 13744, 4, 142075, 0, 0
UMA Hash: 256, 0, 1, 14, 5, 0, 0
...
Because it looks to me like it´s used anyway, or am I misinterpreting the output? Doing a
# sysctl -a | grep uma
didn´t reveal anything else related to it, so if ZFS isn´t using UMA nothing should, right?[*]: http://forums.freebsd.org/viewtopic.php?f=48&t=41880&start=50#p259656
