May 15, 201016 yr I brought the server down to do a down grade to 4.5.1 from 4.5.3 replaced bzroot and bzimage put usb back in reboot ERROR: DISK BOOT Failure Ok - so replaced with the 4.5.3 files Again same error: DISK BOOT Failure Checked USB stick on another computer - it boots to Linux fine off the usb stick I have NOT changed any thing on the BIOS on my server. I tried switching to different USB ports No luck No updates were done to the server, no hardware was added or taken out. I am totally baffled. AND my server is down. Kids are not happy!
May 15, 201016 yr Author Update: So I opened up the machine Noticed that the power supply fan was still going on even with the machine turned off I unplugged the machine Plugged in the machine and it booted from the USB! Go figure! Have to put the 4.5.1 files back on and reboot for final test. Posting in case someone else benefits from this.
May 15, 201016 yr Author Did an Init 0 to shutdown the machine Unmounting remote file system seems to be taking a lot of time - unusually so lot of activity on one drive and parity drive. Hmmmmmm
May 15, 201016 yr Did an Init 0 to shutdown the machine Unmounting remote file system seems to be taking a lot of time - unusually so lot of activity on one drive and parity drive. Hmmmmmm Init 0 will NOT cleanly stop the array. Stop the array first, or you'll probably be faced with a forced parity check upon power up.

May 15, 201016 yr Author Joe, what is the best way to shut down the server from a linux command prompt ie: no browser
May 15, 201016 yr Author Looks like the drive that was hanging is bad - replaced with spare. Drive has been running since Jan 2008 - a Western Digital 500gig paid $99 for it in 2008 My old 500gig drives are starting to fail one at a time recently did a warranty swap on a Seagate 500gig 5 year warranty! I guess time to move to 2Tb drives.
May 15, 201016 yr Joe, what is the best way to shut down the server from a linux command prompt ie: no browser Easiest if you are using the current version of unRAID and have no add-ons that are keeping disks busy, is to type powerdown It will NOT work if any disk is busy. There is a "/sbin/powerdown" add-on written by WeeboTech that will kill processed holding disks that are busy. The individual commands are in this thread: http://lime-technology.com/forum/index.php?topic=6255.msg60701#msg60701 You will not be able to un-mount a disk if it is busy. Joe L.
