lennygman Posted November 6, 2017 Author Share Posted November 6, 2017 ok, I will start on that.. Only question on copy I got: if I just copy the data which is part of the share that spans disk4 and other diskX, will the complete data of the share be available? So i just pick another available drive and copy all data into a temp folder? like backup_disk4? Link to comment
JorgeB Posted November 6, 2017 Share Posted November 6, 2017 Use midnight commander (mc on the console) and copy from /mnt/disk4 to another disk, e.g., /mnt/disk5 , shares are all the top folders. Link to comment
lennygman Posted November 6, 2017 Author Share Posted November 6, 2017 Ok .. All data has been copied over to another drive. What can I do with drive4 to see if it needs RMA or the errors are just bad data? Link to comment
JorgeB Posted November 6, 2017 Share Posted November 6, 2017 Start by running and extended SMART test. Link to comment
lennygman Posted November 6, 2017 Author Share Posted November 6, 2017 Ok took a while. Says completed with errors but Smarts says passed I dont know what errors it is referring tower-smart-20171106-1200.zip Link to comment
JorgeB Posted November 6, 2017 Share Posted November 6, 2017 The important part is this: Quote Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 47720 - So the disk appears to be fine, but those errors in unRAID are hardware related, and they looked like a disk problem. Maybe try swapping cables with a different disk and see how it behaves, you need to do a parity check anyway so do it after swapping the cables. Link to comment
lennygman Posted November 7, 2017 Author Share Posted November 7, 2017 Hi, I moved cables around 2 drives.. "Error" drive and another that was always clean. Tower been running for hours all drives are clean. I will start parity check I guess. Strange that errors just went away but happy nevertheless Thankyou again for your support Link to comment
lennygman Posted November 7, 2017 Author Share Posted November 7, 2017 BTW.. should i check off "Write corrections to parity" ? Check will start Parity-Check. Write corrections to parity Link to comment
JorgeB Posted November 7, 2017 Share Posted November 7, 2017 25 minutes ago, lennygman said: should i check off "Write corrections to parity" ? Yes, since sync errors are expected. Link to comment
lennygman Posted November 8, 2017 Author Share Posted November 8, 2017 Parity check finished with errors. Drive still showing 0 errors. Last check completed on Tue 07 Nov 2017 09:31:29 PM EST (today), finding 238658 errors. Duration: 10 hours, 13 minutes, 54 seconds. Average speed: 81.5 MB/sec Is there anything else I should do?

JorgeB Posted November 8, 2017 Share Posted November 8, 2017 Keep an eye on it but for now it's OK. Link to comment
SSD Posted November 8, 2017 Share Posted November 8, 2017 This is an excellent thread explaining how to handle a disk dropping offline and when to and when not to do a rebuild. We had a similar thread last week where a user too quickly did a drive rebuiqld and lost data as a result. Link to comment
