I mentioned this in another thread, but for the most part Unraid has served me well and I only really need to do any real maintenance every few years. Therefore I never remember how to do anything significant and when I search these forums and the googles i get 50 different answers. So if someone can direct me to a tutorial for adding hard drives to a V6.9 system I'd appreciate it. I also have another problem with a new drive. I do know, turn off unraid, install new drives, start up unraid, start array, then pre-clear new drives, after that I'm at a loss. Yes I can figure out how to get it to work, by mulling about, but I think that I did that last time and didn't really have the drive, parity in this case, working correctly. So help me out. Now for the error, I just started pre-clear on the two new 8tb drives and after only 10 minutes I got errors on one of the drives, I think it was CRC error, not sure it's in the log attached and there is "error" with the thumbs down next to the drive on the Dashboard page. So should I get a replacement? or Run Pre-Clear again after it's done? tower-diagnostics-20210504-1815.zip

Thanks. Already completed!! We're up and running again. Also, I switched the bay that parity was in and so far so more crc errors.

Got it. Thanks. Yes copied everything.

Ok I hate to be that guy, but what's the best way to take that disk 3 and reformat it so that my system/parity is intact when I'm done? I read the wiki, but seems like every time I do something there's 50 ways to do it.

Ok thanks.

Ok I restarted. Then used binhex krusader to transfer files from disk3. This morning I had a "Unraid Parity Disk SMART Health [199]:04-04-2021 20:48 Warning [Tower] - udma crc error is 68 WDC-yada yada yada" this is parity disk 1. So what does that mean after doing all those parity checks. Is the drive no bueno? Also included the diag file. tower-diagnostics-20210405-0810.zip

Gotcha. Thanks.

Umm, cough. Was it really named after him? I didn't read the wiki, that dude was too creepy looking. Will move data and reformat, then rebuild parity? Or does it do that on the fly when reformatting the drive? The only thing I have in dockers is the binhex krusader which I just use every once in a while to move files between disks which I'll do when moving disk 3 to reformat. Hardly ever do hard shutdown and have a battery backup. Might have lost power and battery backup once or twice in the past year. Again, thanks for the help. So I take it I can update unraid, it's telling me 6.9.1 is available and then I can restart?

Ok second parity check done. Zero errors. See final attached diagnostic report. Couple questions still: 1. You said, "Parity check doesn't do anything at all to any of your data disks, and in fact, your data disks seem to all be mountable and none disabled." so does that mean during a self correcting parity check it corrects my parities and not the data disks? Meaning, that the couple of files I found that don't play correctly, corrupted in some way, but still kind of playable, that's a result of something else? 2. You gave me lots of tasks. Now that I've got a zero sum parity check what do I want to do next? You mention did I tell it to trust the parity or have a valid parity? What do I do about that, or did I do that already by running the two parity checks? 3. Do we investigate further about the 183,337 parity errors I got the first time? Bad HDD? Will I notice any corrupted files? 4. What should we do about disc3 Paul Reiser FS? Thanks a bunch!! tower-diagnostics-20210404-1623.zip

Done. See log. Thanks. Oh, starting a NON-correcting parity check. tower-diagnostics-20210403-1933.zip

Ok, I'll check the cable, later on and maybe move the position. Can't hurt.

Sweet. I appreciate the help!! I'll do the rest when the check is over. As far as the bad connection, I'm using one of those 20 bay enclosure units with all the cables hooked to 4 or so break out boards, I keep the parities in the same area on the same break out board. So once this is all done should I move that parity to a different location? How can you tell if a connection is kind of bad or test whether it's stable?

What do you mean by connection issues, do you mean physically, like a bad cable? or something in the software? Honestly don't remember, but I updated the whole system back in Jan 2020 where I changed out all my old disks, 1tbs and 2tbs, with new 4tb ones and two new 8tb paritites, so I'm assuming I built a new parity from scratch and trusted it. Bad Ram, memtest? when I do all the other stuff you suggest? Why is disc3 Paul Reiser FS? No idea. Should I change it?

There is on Parity 1, but not parity 2 that one says healthy.

Thanks I appreciate the help. Here's the diag zipper container. tower-diagnostics-20210403-1758.zip

LOL that was almost a year and half ago. I can't remember what i had for lunch. I'll figure out how to get diagnostics when the check is over. It has about an hour left.

Sorry for being dim, I'm not a power user. I know very little about unraid. As I said over the last 15 years I've never had a problem. So what should I expect when the parity check is over, rebuilt files or corrupt files? Or something new that we can't figure out because Stephen Hawking is among the stars now?

Ok, something I should check out while it's running it's check or afterward? Also, maybe it was one drive as of now the parity sync errors correction has stopped climbing. So maybe a bad or going bad HDD?

I've been using unraid for probably 15+ years if not longer. Never had a real problem. Mainly I let it do it's thing, meaning I don't know how to use it very well. Then last night a file I know was good was not playing correctly on VLC. So I hadn't done a parity check in almost a year. Using 2 Parity Drives, 10 Disks, 40 TB, Unraid Pro Version 6.8.3 It's now 50% done and has more than 180,000 sync errors corrected. Should I be worried and if so what will he the consequences? And what should I do once the parity check is over?

Thanks again. Fingers crossed.

OK so got the new drive in and I clicked start array and rebuild drive. Now it gave me a disk warning in yellow for that new disk 8 saying "Unraid Disk 8 Error, Disk 8, drive not ready, content being reconstructed" I assume that's normal and it's not really a disk error, just that it's rebuilding a drive? Also, should I go ahead and pre-clear other drives I'm going to use to replace other bad HDD now? or wait until Disk 8 is rebuilt?

THANKS!!! So should I pre-clear the new disk or just risk it so I can rebuild disk 8 right away? I've got 3 new 4 TB WD Red drives arriving in about 1/2 hour from Amazon Prime Now.

Ok so I haven't messed with my Unraid for years as it works just fine, but I ran a check while I was out of town and it came up with zero errors. So I ended up updating my unraid from v6.something. to the latest v6.8.0. a couple days ago. I also added docker community apps, unallocated drives, binhex-krusader and pre-clear. I've used Krusder with no problem. After updating the OS I enabled pop up messages, which I don't think i had enabled before, so maybe all this has been happening for a while and I didn't know it. After updating and enabling messages I got the following: unRAID Disk 1 SMART health [199]: *Current Date and Time Warning [TOWER] - udma crc error count is 10 *HDD Serial and Model (sde) unRAID Disk 6 SMART health [5]: *Current Date and Time Warning [TOWER] - reallocated sector ct is 155 *HDD Serial and Model (sdc) unRAID Disk 6 SMART health [187]: *Current Date and Time Warning [TOWER] - reported uncorrect is 544 *HDD Serial and Model (sdc) unRAID Disk 7 SMART health [187]: *Current Date and Time Warning [TOWER] - reported uncorrect is 6 *HDD Serial and Model (sdb) unRAID Disk 8 SMART health [5]: *Current Date and Time Warning [TOWER] - reallocated sector ct is 105 *HDD Serial and Model (sdg) Now today disk 8 looks to have failed, red X, and when I look at tool > syslog I see many hard drives have read errors. See attached zips. So since I got those disk errors a few days ago I have some new hard drives coming and I'm going to rebuild my entire system and get rid of the old smaller drives. My question right now is, what should I do to preserve my data? Meaning what is the problem with disk 8 and what should I do about that right now? Could updating to v6.8 be a problem? I'd love some advise. Thanks. tower-diagnostics-20200106-1402.zip tower-smart-20200106-1404.zip

I'm not sure why people are referring to OSX, I'm using a PC Windows 7. So all that makes no sense to me. I tried the remove all in the directory, same result. I'll try setting new permissions, not sure how, but I'll look it up.

Thanks for the suggestion. I tried what you instructed above, but it won't delete. It says "cannot delete directory not empty" I tried deleting the folder inside that and it wouldn't delete that either. Weird thing is I can rename the folders, but not delete it. Not sure what you mean by "I thought the file was a file but in fact it was a bundle/folder which looks like a single file with an extension and contains other files. To delete it I had to add the extension as in .sparsebundle I could only delete it in telnet like below." Could you explain further? Thanks.
