Hi,
My -CURRENT system has been experiencing problems since I converted
it to cam awhile back. The following show up on my console, and then
my disks are useless until I completely shutdown, powerdown my drive
array, power it back on, and reboot. I have 4 identical drives configured
as a ccd. They have been serving me well more about a year...
If anyone has any ideas on how I can track down the problem, please
let me know!
Thanks,
John
