Hi!
On Centos-7:
$ cat /etc/centos-release
CentOS Linux release 7.8.2003 (Core)
Was running du to examine the sizes of my backups and
found du hung, running "ps -eLf /mnt/backup/backups" shows this:
# ps -eLf | grep du
root 1185 1 1185 0 1 May01 ? 00:00:00

/mnt/backup/backups
even after killing the du.
there were two DUs shown, I killed the parent (presumably the one I
started) but the one that remains seems to be un-killable.
This is what the output looked like before I killed du:
# ps -eLf | grep du

root 12125 19449 12125 0 1 15:17 pts/0 00:00:00 grep --color=auto du
Oh, and I never did get the du out put I expected.
Anyone got a clue?
Thanks in advance!
Fred

You could try "umount -f /mnt/backup" if you can't get the mount working by any other means.? If that doesn't work, then "umount -l /mnt/backup" and reboot.

A reboot solved it, powering the device off/on made no difference, as did replugging the cable. Afterwards, I recalled that I had run a much belated yum update 2 or 3 days ago and had failed/forgotten to reboot. Probably some necessary item had gotten wedged somehow because of that. (seen it before, but not with a USB device.) Thanks for the reply, though.
