X-Mailer: nmh v0.26 Organization: Palmer & Harvey McLane Date: Tue, 01 Dec 1998 13:59:59 +0000 From: Dom Mitchell Message-Id: Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi there, I'm seeing a curious problem with my NFS mounted home directory... Every now and again, it just hangs, in the usual NFS fashion with a message: Oct 25 14:28:09 voodoo /kernel: nfs server admin:/export/home: not responding % grep /home /etc/fstab admin:/export/home /home nfs rw,-i,-3,-T 0 0 % uname -a FreeBSD voodoo.pandhm.co.uk 2.2.8-RELEASE FreeBSD 2.2.8-RELEASE #0: Mon Nov 30 05:15:30 GMT 1998 root@voodoo.pandhm.co.uk:/usr/src/sys/compile/VOODOO i386 % ifconfig xl0 xl0: flags=8843 mtu 1500 inet 10.100.35.12 netmask 0xffff0000 broadcast 10.100.255.255 ether 00:60:08:76:7d:56 media: 100baseTX supported media: autoselect 100baseTX 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP 10baseT/UTP It's running on a 100BaseT switched network to a Solaris 2.6 server. The funny thing is that when it hangs, it doesn't recover, the way that I have seen before with these problems. What is even weirder (to me) is that I can mount the problem filesystem in a different place (say, /mnt) and it works fine! The underlying network connectivity isn't going away. BTW, I've also started using the access cache which has just recently been imported. It seems to work great (aside from this slight problem, but I'm not sure if it's related). I realise that this isn't enough to go on for solving the problem. What other things can I try when the /home mount gets hung again? Can I force a crash dump to take a closer look? Thanks for any assistance. -- Dom Mitchell -- Palmer & Harvey McLane -- Unix Systems Administrator ``Those who do not understand Unix are condemned to reinvent it, poorly.'' -- Henry Spencer To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
