March 22, 20188 yr I would like to double check with the community on my situation, hoping i haven't done things incorrectly. I had a drive fail on me. Ive checked the cables, swapped them around and still the same drive had a red X. Steps i have done so far: Stopped array Unassigned failed drive Stated array New config Stated parity sync. I have about 6hrs to go on my parity sync, but i have noticed some folders are missing from my shares. Now in fairly certain that the failed drive didnt contain these folders to begin with. Question is - How do i look at the contents of that drive again? once parity is done, can i just put it back into the array to check? or will i need to run newconfig again and rebuild parity? Or do some folders go missing during a parity sync/rebuild? Cheers Edited March 25, 20188 yr by bdydrp

Since it isn't possible to do a New Config with the array started, this can't be exactly what you did. In any case, what it sounds like what you did is the wrong thing to do. You should have rebuilt the data disk. Instead, you have rebuilt parity without the data disk. Which means there is no way now to rebuild the data disk. Is the unassigned "failed" drive still installed? That would make it simpler to get us the full information we need to tell you how to proceed. Go to Tools - Diagnostics and post the complete diagnostics zip. Obviously, you should have asked first.
March 22, 20188 yr Author @trurl Yes, it is a Typo. Drive is still attached - Just not part of array Just clarify also, i am not replacing the drive with a new one - Just removing it entirely Logs attached Thanks tower-diagnostics-20180322-1611.zip Edited March 22, 20188 yr by bdydrp added mention

March 22, 20188 yr Author Thanks @johnnie.black Ill have a look at the UD plugin and see what i can find. Im still positive that the drive in question didnt contain any of my missing folders.....but i will soon find out!
March 22, 20188 yr Author So, turns out i was wrong. After mounting using UD plugin, theres my files! Is this correct in getting my data back. Telnet open MC From /mnt/disks/*faileddrive*/media to /mnt/user/media Where media is my share name!
March 22, 20188 yr Author Thanks! Ive already seen an error in one file when trying to copy the data. Is there anything i can do with this drive to try and correct the errors? or its toast!
March 22, 20188 yr Community Expert You can use ddrescue to clone the disk, it will skip read errors, but those files will be corrupt, than can be better than nothing for e.g. video files, movies, where a little glitch may not be so bad.
March 22, 20188 yr Author Thanks Johnnie Ill take a look at the link. As for now, i already have the files copying. I can easily cross check both locations and see what didn't get transferred after MC is completed Thanks for your help - Appreciate it!
