Performance dropped from somewhat 700MByte/sec to 2MByte/sec on the main = NAS system. I couldn't find the problem in time so we rebooted. Uptime was around = 150 days. After reboot everything was back to normal. We will reinstall the system with a stock freebsd 9 as no GUI is needed = anymore. best, - -dennis Am 22.03.2012 um 01:18 schrieb andy thomas: > On Wed, 21 Mar 2012, Artem Belevich wrote: >=20 >> On Wed, Mar 21, 2012 at 4:56 PM, andy thomas = wrote: >>> A server running 64-bit FreeBSD 8.0 boots from a SATA disk and then = mounts a >> ... >>> But over a period of time, this performance begins to deteriorate = and after >>> 180 days of uptime >>=20 >> If it's indeed 8.0 that you are running, I would strongly recommend >> upgrading to 8-STABLE or 8.3 when it's released. >> A *lot* of things in ZFS got fixed/improved since ZFSv13 in 8.0. >=20 > It's running 8.0-RELEASE.
