The info on freefall didn't tell me much. The TCP connection appears to have gone away, which is normal for an NFSv3 mount after 6 minutes of no activity. The "umount -N" won't work because there was a "umount -f" already stuck. Use "umount -N" instead of "umount -f", not after it. The most likely culprit is the bug/fix discussed in PR#256280, but that can only be confirmed by doing a "netstat -a" on both systems before the TCP connection goes away. rscheff@ did not do an errata for this, so the fix is in 13.1, but not 13.0. If you upgrade to 13.1 and still experience the hangs, enter that here and try to get a "netstat -a" on both client and server within 6minutes of the hang. Then wait until the connection has gone away and then see if the mount is still hung. --=20 You are receiving this mail because: You are the assignee for the bug.=
