July 3, 201313 yr So here is my problem, I recently upgraded to RC15a and experienced a slow down in parity speed. It took my server 25 hours to complete a parity rebuild of my Disabled Disk 2 (up from 12 hours). I also experienced a slow down of the unraid webgui. So I downgraded back to RCa13 and all my speeds increased. While I had been transferring files onto my server during the night my roommate decided my server was making to much nice while sleeping. So he pulled the power plug and crashed my server. I was not too happy about that to say the least. When I woke up the next day I initiated a parity check. It completed with out any errors so I thought nothing of it. I just recently transferred more files to it, and the GUI crashed. I had to reset the server myself. I used the poweredown script from the command line. It took almost and hour to shutdown that night. When it completed I rebooted and initiated a parity check. It showed up with some errors. I am just not sure if I should believe its an actual drive failure or just something else acting up. Do any of you think it would be a good idea to disable the disk then replace the cabling and try to rebuild the drive. I have the drives in a Norco 4020 so replacing the cables wont be hard. Any thoughts? (Edit) Stock Unraid with no plugins specs in signature Syslog_Pruned.txt
July 3, 201313 yr Author Of course. Why didn't I think of that. I knew I was missing something. I'll post one when I go home on my lunch break. Thanks.
July 4, 201313 yr Author OK I installed Simple Features 1.0.11 to use the built in smart check. I only had a few minutes to run the check before I had to go back to work. When I got back from work I received a warning saying "Errors occurred - Check logs". So I copied as much of the info from the smart checks I could see. Could someone point me in the direction of how to do a smart check from putty. I just don't know what command I should use. Thanks for the help!! Model Family: Western Digital Caviar Green (Adv.

The drive will either stabilize and start to act ok again, or it will completely die. My guess is it's dying, and sooner rather than later. BTW, unmenu has smart tools as well, and it seems to be less intrusive and more stable than simple features.
July 4, 201313 yr Author Ok, thanks for the info. The drive is still covered under warranty so I'll have it replaced. It just happened to be within days of me replace disk 2 so I wasn't sure if something else was up. I usually have unmenu installed as well but I have been having speed issues so I have been trying to run stock as much as possible. Thanks for the help guys. I really appreciate it.
