Running a box I just upgraded on September 30 to 4.11-STABLE. I have what appears a wedged NFS client. The NFS server was recently replaced with a new box after a failure. However, now the client can't umount the old one. How can I clear this up without a reboot (which is a *painful* thing to do on a production box): [root@w02]# ls /n/lorax1 ls: /n/lorax1: Stale NFS file handle [root@w02]# df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/amrd0s2a 128990 41902 76770 35% / /dev/amrd0s2f 201518 38654 146744 21% /u/w02 /dev/amrd0s2e 604718 396194 160148 71% /usr /dev/amrd0s2g 15285872 12972172 1090832 92% /var mfs:23 32206 354 29276 1% /tmp procfs 4 4 0 100% /proc [root@w02]# umount /n/lorax1 umount: unmount of /n/lorax1 failed: Device busy [root@w02]# mount /n/lorax1 mount: /n/lorax1: Stale NFS file handle also, fstat shows nothing sitting inside of /n/lorax1 as its working directory.
