Hi,
I've been using unRAID for about a year now with ZERO issues whatsoever, i love this thing.
When i first configured my array I setup email notification's as the guide I used for configuration suggested and have been pleased with all the many "PASS" emails I've received. This morning i got my first heart attack from the system and got a "FAIL" message with the below error message:
Disk 7 - ST2000DM001-1CH164_Z1E42NBH (sdc) - active 24 C (disk has read errors) [NOK]
I'll say I'm above average when it comes to tech savviness, storage, and have even dealt with enterprise grade storage in one form of another for the past 7 years in my career. But when it comes to my own personal data on unRAID there's some parts that are still new to me. After doing some Googling, browsing the forums, and even Reddit, I've seen some mixed results on my next course of action and figure its best to ask here.
I've seen mixed recommendations of people saying the filesystem on that drive needs to be fixed etc.
Currently i turned off Plex so i don't have any read requests going to the array. The only other items that connect to it is my main desktop PC and a Firestick (both i stopped accessing any files as soon as i saw the error message this morning). The array is currently online, and parity is valid. Is it as simple as just stopping the array, powering down, pulling that disk and replacing with a new one (which i know a pre-clear should be run on) or do i need to do anything with the file system on disk 7? I also saw another recommendation of after the rebuild being complete to run a parity check with "write corrections to parity" turned off.
I've attached my diagnostic file to this post and am looking forward to any responses.
Data that's on the array is a backup of my personal files on my main PC (documents, photos, music) and my DVD rips.
Thanks!
