This is a long-standing problem. When we had F230s one of them would regularly go slower and slower and would require a reboot. CIFS would usually produce the hung message. We finally resorted to automated twice-weekly reboots which got around the problem.
The filer is desperately short of a "really_really_reboot_NOW" command. Someone at Netapp suggested pressing the reset button and typing "sync" but guess what - that provokes a core dump too!

I have just had to reboot our filer for the second time in about 3 months. Both times the reboot failed with the error:
A CIFS I/O operation may be hung. Shutdown the system using halt-d and report this incident to NetApp.
But I don't want to do a "halt -d". This causes a core dump which means that the filer may be down for about 10 mins. Is there a way of forcing a halt without using the -d switch (halt on its own just gives the CIFS error message again). I'm currently running 5.3.1D5.

PS The problem that caused me to reboot was that I was getting the error "Cannot find logon server" from PCs trying to connect to the filer. The reboot fixed this. Any ideas?
