Cannot shutdown computer or kill -9 hung rsync
We are running Redhat 8 (upgraded kernel to 2.4.18 last year) and cannot shutdown after rsync hangs when backing up to an external USB harddrive. Typically the rsync command (1 line) gets through a few thousand files, but always hangs in the same place.
When we try to do a "shutdown -r now" or "shutdown -h now" from the terminal, nothing happens other than walling all logged in users that the system will shutdown. The hung rsync cannot be killed either (and it's not a zombie), not even with kill -9 (SIGKILL).
In /var/log/messages, nothing is getting logged either - just a reboot message:
May 5 13:14:33 linux1 shutdown: shutting down for system reboot
Any ideas on what we can do?
