March 28, 201610 yr So is there an issue with this Hitachi disk? Why are all the disks listed under Unassigned Devices? I tried to go and look at SMART but it doesn't show anything. I'm going to try shutdown and inspect cables since I just had the case open 24hrs ago.
March 28, 201610 yr Author It took about 30 minutes to stop the array. I selected to stop the array from the GUI, the status on the bottom continued to repeat something about 'unmounting the disks'. I restarted my windows machine (only other PC on network) to see if that was holding up the array stop somehow. I pulled the network cable, that didn't work either. I then logged on via the console CLI and started to follow the process in the docs to "cleanly Stop the array from the command line[edit]". I entered the first command listed "/root/samba stop" then tried the second set of commands "umount /dev/md1" the response was that this drive was not mounted. After a few minutes of trying the umount command I noticed the GUI had come back and asked for user/passwd. After logging into the GUI I found the array stopped so I was able to shutdown. I checked the cables and reboot, the drive is still red X. This drive was installed new on 3/4/16 after preclear in order to replace another failed drive just like it. Is it coincidence that the same Disk 2 has failed after 1 month twice?

March 28, 201610 yr Community Expert Looks more like a bad sata cable, if you have it post the syslog before rebooting. 199 UDMA_CRC_Error_Count 0x000a 200 200 000 Old_age Always - 13 If you don't have the syslog replace cable and you can try to rebuild to same disk.
March 28, 201610 yr Author This is SMART after the reboot. I didn't see the unfinished procedure documentation until after rebooting, so I don't have a syslog from before. https://lime-technology.com/wiki/index.php/Fixing_a_drive_with_red_status_indicator
March 28, 201610 yr Author What happens if I start the rebuild and the disk is bad? Am I taking additional risk by trying to rebuild with this disk vs a new one from Best Buy tomorrow? (I'm trying to look around to figure out how to rebuild the same disk.) I've assigned a new disk before to start the rebuild but not the same disk. And that was a month ago, I'm having trouble remembering how I did it then.
March 28, 201610 yr Community Expert Not really, but if the rebuild doesn't successfully complete then the disk is probably bad even though SMART looks fine, in that case use a new and tested replacement disk.
March 28, 201610 yr Community Expert To rebuild on the same disk: -stop array -unassign disabled disk (select "no device") -start array -stop array -reassign disk -start array to begin rebuild
March 28, 201610 yr Author Also, note that in the screen shot before the reboot all the drives are show in the Unassigned Devices section. Is this expected behavior for a failed drive/sata cable? sorry I didn't get syslogs before reboot
March 28, 201610 yr Author To rebuild on the same disk: -stop array -unassign disabled disk (select "no device") -start array -stop array -reassign disk -start array to begin rebuild thanks! Rebuild started
March 28, 201610 yr Author Rebuild was successful. Any idea why in the OP screen shot before the reboot all the drives are show in the Unassigned Devices section?
March 28, 201610 yr Community Expert Any idea why in the OP screen shot before the reboot all the drives are show in the Unassigned Devices section? I seem to remember this being mentioned before if the array ha not been started. Was it started in this case?
