Hi there,
Had another stall, server running 2.6.24.7, clients running 2.6.27-rc5.
On the server the netstat -t gave during stall:
grant@deltree:~$ netstat -t Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 localhost:50087 localhost:4743 ESTABLISHED tcp 0 52 deltree.mire.mine.n:ssh sillywin.mire.mine:3052 ESTABLISHED tcp 0 0 deltree.mire.mine.n:ssh sillywin.mire.mine:3051 ESTABLISHED tcp 0 0 deltree.mire.mine.n:ssh sillywin.mire.mine:1056 ESTABLISHED tcp 0 0 localhost:4743 localhost:50087 ESTABLISHED
after stall, shows the delay seems to be in making the NFS connection: grant@deltree:~$ netstat -t Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 localhost:50087 localhost:4743 ESTABLISHED tcp 0 0 deltree.mire.mine.n:ssh sillywin.mire.mine:3052 ESTABLISHED tcp 0 0 deltree.mire.mine.n:ssh sillywin.mire.mine:3051 ESTABLISHED tcp 0 0 deltree.mire.mine.n:ssh sillywin.mire.mine:1056 ESTABLISHED tcp 0 0 localhost:4743 localhost:50087 ESTABLISHED tcp 0 0 deltree.mire.mine.:nfsd pooh.mire.mine.nu:rtip ESTABLISHED
On 'pooh', I opened a new root terminal and run a command from nfs export from deltree, this is when the stall happened, pooh had been up for about five hours, this from /var/log/messages: Aug 30 19:10:21 pooh sshd[2615]: Accepted publickey for root from 192.168.1.36 port 1246 ssh2
Just before doing that I'd told 'tosh' to halt via ssh terminal and the server recorded in /var/log/messages: Aug 30 19:11:03 deltree mountd[573]: authenticated unmount request from tosh.mire.mine.nu:680 for /home/common (/home/common)
Just coincidence? .config + dmesg for the clients (.27-rc5a): http://bugsplatter.id.au/kernel/boxen/pooh/ http://bugsplatter.id.au/kernel/boxen/toshi/ server (.24.7a): http://bugsplatter.id.au/kernel/boxen/deltree/
Grant.
