Message-ID: <20070802171450.7c9b4af3@zeus.pccl.info> Date: Thu, 2 Aug 2007 17:14:50 +0100 From: Andrew Clayton <andrew@...ital-domain.net> To: linux-kernel@...r.kernel.org Subject: [NFSD OOPS] 2.6.23-rc1-git10 Hi, Got the following oopsen just now from 2.6.23-rc1-git10 on a 2 processor Opteron with 2GB RAM. System is running 64bit Fedora Core 6. nfsd is exporting directories from a XFS filesystem on top a software RAID 5 array comprising 3 x 250GB SATA disks using the sata_sil driver. Amongst other things, users (about 12) home directories are automounted from it. Some problems seem to start when I was experimenting with the stripe_cache_size of the md array. People could no longer run some apps and having general NFS issues. IIRC I had dropped the stripe_cache_size down from 8192 to 768 then I attempted to restart nfsd via /etc/rc.d/init.d/nfsd restart I then got the Oopses and the machine locked up needing a power cycle.
