CyberMew Posted November 20, 2016 Share Posted November 20, 2016 saw the red x icon (Device is disabled, contents emulated.). there is no issues with the drive's logs.. i tried going into the drive and see no problems with smart, so i reseated the drive (after shutting down), and now the smart attributes info and capabilities are not shown, http://i.imgur.com/YFrFZNy.png?1. I have tried connecting to another sata cable as well as port. the array status is also Array is Started, but Parity is invalid. Any idea how can the array start if the drive is not accessible? and what is the meaning of Device is disabled, contents emulated.? I don't wish to break anything so for now I have stopped the array. tower-diagnostics-20161120-1947.zip Quote Link to comment
JorgeB Posted November 20, 2016 Share Posted November 20, 2016 Disk has SMART disable, when it's part of the array unRAID enables it. Turn it on by typing: smartctl -s on /dev/sdb and post new diagnostics. Also, did you by any change grabbed the diagnostics before rebooting? If yes post those also. Quote Link to comment
CyberMew Posted November 20, 2016 Author Share Posted November 20, 2016 Thanks, reenabled it manually, and now its shown. However it is still a red x, not sure why.. i didnt get the previous diagnostics before reboot tower-diagnostics-20161120-2245.zip Quote Link to comment
JorgeB Posted November 20, 2016 Share Posted November 20, 2016 Red X means that a write to that disk failed, so unRAID disable it, without the diagnostics from when it was disable we can't see what happened. SMART look OK, though there are some CRC errors, you may want to replace that SATA cable, then you can rebuild using the same disk, if it happens again grabs the diags before rebooting. To rebuild to the same disk: -stop array -unassign that disk, select no device -start array -stop array -re-assign disk -start array to begin rebuild. Quote Link to comment
CyberMew Posted November 20, 2016 Author Share Posted November 20, 2016 Ah ok thanks, the errors were from previously. The drive is rebuilding now though it seems to be 9 days left (3.5MB/sec lol) .. so any write to the 'failed' drive is actually to the parity drive, hence the word emulated contents?

JorgeB Posted November 20, 2016 Share Posted November 20, 2016 That's very slow, post new diagnostics. Did you replace the SATA cable? Quote Link to comment
CyberMew Posted November 20, 2016 Author Share Posted November 20, 2016 I turned off torrents and it seems to be alright now, 30+MB/sec. The sata cable has been changed when I did the second restart. So any writes to the drive now will update the parity and rebuild accordingly? Quote Link to comment
JorgeB Posted November 20, 2016 Share Posted November 20, 2016 Yes, you can use it normally although it's going to be slower, avoid large writes. Quote Link to comment
CyberMew Posted November 20, 2016 Author Share Posted November 20, 2016 Thank you very much for your help and explanations! Fingers crossed now.. Quote Link to comment
garycase Posted November 20, 2016 Share Posted November 20, 2016 ... I turned off torrents and it seems to be alright now, 30+MB/sec. That easily explains the VERY slow performance. You should NOT use the array at all -- writes or reads -- during parity checks, parity sync, or drive rebuilds. This will cause a MAJOR degradation of performance. It "works" ... but it does so VERY slowly. In fact, a series of operations will take FAR longer to do simultaneously in that scenario than the total time it would take to do them one-at-a-time.

CyberMew Posted November 20, 2016 Author Share Posted November 20, 2016 It would be good if there's an option to turn off plugins dockers and vm when performing array operations Quote Link to comment
JorgeB Posted November 20, 2016 Share Posted November 20, 2016 Most use cache or an unassigned device for those, it's faster and doesn't interfere with the array. Quote Link to comment
