The first time that a filesystem is mounted (eg. from /etc/fstab), the mount will usually succeed. Unmounting and then attempting to mount the same filesystem again results in the hang --- amd(8) will trigger this behaviour quite reliably. Forcing nfs v2 makes no difference. Occasionally an attempted mount will cause the whole machine to freeze: in any case the only way I've found to get rid on the hung mount_nfs process is to reboot. Mounting from other unix (FreBSD, Linux) servers doesn't result in hangs. >How-To-Repeat: mount -t nfs -o rw solaris-server:/filesystem /mnt umount /mnt mount -t nfs -o rw solaris-server:/filesystem /mnt >Fix: Not known >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
