yanksno1 Posted August 31, 2020 Share Posted August 31, 2020 So checked my Unraid Server this morning and shocked to see the SMART error listed on my first HDD. 5 Reallocated sector count was marked and doing research it looks like the drive is failing right and it should be replaced ASAP right? I recently added a shucked 2nd data drive to the pool, which I'm now thinking of moving that to replace the drive. Does that sound like a good plan to you guys? Nothing's on that drive yet, was just sitting there. I can then wait for another sale to buy another one. Just wanted to run that by you guys before I take out the drive. I did try re-arranging the drives and obviously that didn't work. I first took out the Disk 1 I had there (after marking it as No Device before shutting it down). Since I already had the Disk 2 assigned in Unraid, it wouldn't let me put it in the Disk 1 spot with the array stopped. Is there anyway I can re-assign Disk 2 to Disk 1 or do I have to replace it (Disk 1)? Quote Link to comment

trurl Posted August 31, 2020 Share Posted August 31, 2020 As you discovered, you can't remove disk2. You would have to rebuild parity without disk2 to get it out of the array. Which would require using disk1 for the parity rebuild. Anyway, 8 Reallocated isn't necessarily a reason to replace. Run an extended SMART test on it and if it passes and the count doesn't increase just acknowledge the warning by clicking on it on the Dashboard. Quote Link to comment
yanksno1 Posted August 31, 2020 Author Share Posted August 31, 2020 Thanks for the idea about re-building the parity drive without Disk 2 there. With the array stopped, if I take Disk 2 out would I be able to restart the array without it there? I tried a short SMART self-test one but that didn't do anything. Just started an extended one, we'll see what that does. Quote Link to comment
trurl Posted August 31, 2020 Share Posted August 31, 2020 I wasn't trying to give you an idea about removing disk 2. If you don't think you can trust disk 1 why would you trust it for parity rebuild? Quote Link to comment
yanksno1 Posted August 31, 2020 Author Share Posted August 31, 2020 Was hoping it'd last long enough to do it! haha Quote Link to comment
trurl Posted August 31, 2020 Share Posted August 31, 2020 It probably would. Let's see what the test says, it will take several hours. 1 Quote Link to comment
trurl Posted September 1, 2020 Share Posted September 1, 2020 Just noticed you have dual parity. Probably make more sense to use parity2 to replace disk1 Quote Link to comment
yanksno1 Posted September 1, 2020 Author Share Posted September 1, 2020 That's a good idea. And I won't have a problem there taking it out of that spot when I try to start the array? Quote Link to comment
trurl Posted September 1, 2020 Share Posted September 1, 2020 I think you can just unassign it and start the array. If it says it is missing then you would have to New Config without it, which is what you would have to do to remove disk2, except in the case of removing parity2 you wouldn't have to rebuild parity. 1 Quote Link to comment
yanksno1 Posted September 2, 2020 Author Share Posted September 2, 2020 The SMART test result finished last night and yielded a Completed without error result. Think it's "safe" to run for now or I should replace it (hopefully taking the Parity 2 drive out)? Quote Link to comment
trurl Posted September 2, 2020 Share Posted September 2, 2020 I would just run with it. Do you have Notifications setup to alert you immediately by email or other agent as soon as a problem is detected? Quote Link to comment
yanksno1 Posted September 2, 2020 Author Share Posted September 2, 2020 I tried to get that going (tried both Gmail and Telegram), but never did. Sounds like a plan, I'll just run with it and see if it gets worse. I'll prob wait for another sale to have one ready to go. Thanks for the help/suggestions! Quote Link to comment
