Hi,
I have a production iSCSI system (on zfs of course) with 15 ssd disks
and it's often suffering from TRIMs.
Well, I know what TRIM is for, and I know it's a good thing, but
sometimes (actually often) I'm seeing my disks in gstat are overwhelmed
by the TRIM waves, this looks like a "wave"
Hi all,
I just upgraded from 10.3 to 10.4, and "/etc/rc.d/jail start" is having
problems starting all of my jails:
# /etc/rc.d/jail start
Starting jails:xipbuild_3_3: created
ifconfig:: bad value
jail: xipbuild_3_3_8: /sbin/ifconfig lo1 inet 10.1.1.38/32 alias: failed
xipbuild_3_4: created
ifc
You can indeed tune things here are the relevant sysctls:
sysctl -a | grep trim |grep -v kstat
vfs.zfs.trim.max_interval: 1
vfs.zfs.trim.timeout: 30
vfs.zfs.trim.txg_delay: 32
vfs.zfs.trim.enabled: 1
vfs.zfs.vdev.trim_max_pending: 1
vfs.zfs.vdev.trim_max_active: 64
vfs.zfs.vdev.trim_min_active
