X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 05 Jul 2010 03:07:34 -0000 Collective, I have a fileserver running a zpool of approx. 5TB using mirrored pairs:- While running HEAD sources from May 22nd or so, all was well, however either HEAD or STABLE sources since then cause a non-responsive userland (login/csh stops responding, ssh et al, however the kernel is still running as I can switch vty's). Running 8.0-R allows zpool [status] to return the correct info however... Even with WITNESS and INVARIANTS compiled in, no debug is presented, the machine simply stops responding as above. Machine: 1.8Ghz Celeron 430 3GB ram, 4 * 2TB, 2 * 1TB disks in zpool, 2 * 250GB disks in gmirror for OS. amd64 branch I am running with a GENERIC kernel and no custom sysctl/kernel settings. Does anyone have any suggests as to what I can do to diagnose/debug this issue, or has anyone seen similar? Thanks, Joe
