Hello, all. I have returned home after an extended abscence (months), and found a disk disabled (disk 2). I have procured a replacement disk, and need some advice as to how to proceed. My array is currently running on 6.9.2, and I see there is an update to 6.10.0 available. Also, I cannot access any SMART data for the disabled disk, and to my eye the syslog does not help (me, anyway) determine that actual state of the disk in question. My questions are, should I update the UnRAID OS first, or proceed with the rebuild first? Can anyone shed light on anything of interest in the diagnostics, that my untrained eye doesn't grok. Any other words of wisdom? Thanks in advance. tower-diagnostics-20220522-1057.zip

Thanks. This PSU is about 10 yrs old, but it appears that it is, indeed, missing a -5V rail. Good news!

Don't really have a spare 'puter around to test on, but I can bring it to a friend's house. I did a bit of sleuthing and it seems that the -5V rail is deprecated in the ATX specs, as seen in the last paragraph of this document (http://www.playtool.com/pages/psurailhistory/rails.html). I am not sure if this PS is that did not have that voltage available when new.

I recently ran into a problem whereby my server would not power up. I am planning to renovate the server now. I purchased a little power supply tester box. When plugging in the MB connector everything checks out except the -5V LED does not light up. All other connectors test out fine. I went online to see what this could mean and noticed that more expensive, and presumably better testers, do not even report the -5V signal. My question is: what does this even mean, and is this reason to get another PS? If I had a different tester, I might not even know about the -5V "problem".

Great to hear that. Thanks for the reply Sent from my iPhone using Tapatalk

Hi team. Have been away for a few days and came home to a dead server (deets in sig), will just not spin up at all. Pulled the power supply, and it tests out fine, so it appears to be a MB/CPU issue. This server has been running mostly trouble free for about 10 years, so it owes me nothing at this point. One of the NICs died a couple of months ago, also. I have a new MB (Supermicro X11SSM-F), CPU (Xeon E3-1245), and memory (Nemix 32GB Kit DDR4-2666MHz PC4-21300 ECC Unbuffered Server Memory) en route. Needless to say, I'm a bit sleep deprived from freaking out about it and figuring out the new components, and I know just enough about this topic to make myself dangerous. Is there some best practice advice for how to go ahead and effect the rebuild, or is it just - plug the stuff in, replace the UnRAID USB drive and turn her back on? I am slightly peeved that I can't find my most recent copy of the disk assignments from the server, but I am hoping that the system is smart enough to see that everything is still in the same location in my Norco 4220 chassis. Any words of wisdom would be most appreciated.

Again, many thanks.

Thanks again Johnnie. Just to be extra clear (paranoid) the UnRAID managed device number should always be the same as the disk number, correct? So if I need to zero disk 16, I would use md16. Sorry for the cluelessness.

OK, so back again. I am trying to use the 'clear array drive' script in order to shrink my array. I added a drive to the array earlier today and shortly realized that another drive was acting up. I am in the process of trying to remove the newly added drive by the clear drive and then redeploy it for the dodgy drive to be rebuilt. When I run the script, it finishes instantly and the folder 'clear-me' still remains on the drive in question. This drive was only added to the array and formatted (to do so) so does not have any data on it. I don't see any pesky hidden files, so I am wondering how to get it to zero the drive?

@Limy: truthfully, that sounds like a decent option, however I am unsure that my current ability is up to the task. I have been avoiding VM utilization on my Mac, but may have to rethink it. Thanks for the answer.

Thank you , John. Maybe I should give OSXFUSE another try.. I only need to read so that the data doesn't get dead-ended on the drives if something gets messed up.

SSIA. I would really like a way to at least get at data if the server craps out. I would prefer a native method, as VMs may be beyond my knowledge level at this point. In the past I tried OSXFUSE, but my knowledge, to get it running, was obviously inadequate. Any help would be appreciated.

That's sorta what I had assumed, but always good to get corroboration. Thanks.

I kinda think that drive is not long for this world, too. Unfortunately it is an older drive :-( I thought it interesting that it kinda just disappears without any trace. Here's hoping that someone can shed some light on the info in the syslog. p.s. 'Fix Common Problems' complains that it doesn't know about 'dynamix.smart.drivedb.update' so it MAY be incompatible. p.p.s Thanks for not taking umbrage to me being unsure of the motives behind your 1st reply. So many things can be misconstrued without social interaction context.

So, I can't tell if your comment is an honest question, or a snarky retort, so I'll assume the former: Well, that's part of what I'm trying to figure out. I have pre cleared multiple drives over the past few months with no problem. A different drive is pre clearing, happily, right now. There do seem to be some warnings/errors in the syslog and in my limited knowledge they do not seem to be related to SMART status. I'm just trying to get some definitive info about that DB plugin. As I understand it it just sets up a cron job to update the SMART DB, seems far-fetched to see how that would affect pre clearing in the manner I'm seeing, but that's why i'm asking people way smarter than I. I considered it (the DB plugin) being an issue after I had started a new pre clear. Once it gets through a full cycle i will remove the other plugin and try the wonky drive again. In the mean time I thought I'd ask about it.

So having a strange problem. I have been trying to preclear a disk I had laying around. It starts normally, but a couple hours in it just disappears from the interface. No sign of it in the unassigned disk section of the dashboard, nor on the pre clear plugin page. Just gone. If I reboot the server, it's back. Not really sure what to check. I had just erased and zeroed the whole disk on my desktop machine prior to trying the pre clear. The syslog (attached) seems to have an error that indicates the drive size goes to zero ?!? Not sure what that means. Near the end of the log you'll see various entries for [sdn] that's the disk. tower-diagnostics-20170522-2349.zip

Is the SMART driveDB Update plugin still useful? I can't seem to find any info about it and fix common problems yells about it.

thanks. <DOH> really appreciate your help. However, in relation to the 1st issue above, the new preclear report, which is saved as a text file, contains a full page of this: tput: unknown terminal "screen" tput: unknown terminal "screen" tput: unknown terminal "screen" ... ... tput: unknown terminal "screen" tput: unknown terminal "screen" Obviously related to the status display issue when running the plugin. I know this was happening earlier, and was addressed in an update, but it seems to be rearing it's head again. I have attached diagnostics, should that be helpful. Nope, OSX is trying to open the report as an executable; open the file using TextEdit instead. tower-diagnostics-20160921-1330.zip

On a different note, Below is what all my pre clear reports look like? Needless to say, not terribly helpful. Not sure what to make of this. Especially troubling due to the problem reported above with the progress display. I was hoping to use the reports to see what happened, but there is no useable info in them. Any help would be appreciated.

I'm seeing the same output, do we know what's going on here? I'm tempted to just let it finish, as the plug in status seems to be chugging along. note: I do have nerdtools installed and screen is active. UnRAID 6.1.9 pre clear plugin 2016.09.11a, using default script (not Joe's original)

I just want to thank all those (especially RobJ) for the tips and procedures in this thread. As a novice user I had some trepidation about conversion of all my Reiser disks to XFS. I really wanted to get this done as there is no way to read a Reiser disk on OS X, and there is a FUSE plugin for XFS reads available. Plus, it's not a dead FS. I converted 18 disks (totaling about 60 TB) without a hiccup. I couldn't be happier. Thanks again to all those involved.

I'm on 6.1.9 Oh and invoking the script works fine it's just getting the plugin to do anything that doesn't.

After upgrading to UnRAID 6.1.9 today, the preclear plugin no longer works. It shows drives to be precleared, and indicates that the script is present, but pressing the 'Start Preclear' text button does nothing. It seems like this problem was reported a little while back, but with no resolution. Any ideas? I did try to uninstall and reinstall the plugin, with no effect.

Any chance of rolling in a badblocks routine, could be optional, instead of the typical read and write tests? This would give an awesome workout to a new disk.

moved to a better location. Thanks for the info (see post below VVV)
