OK, I did swap out the power cable (direct PS connector) for a molex to 2 sata split connector. I began the rebuild and it's 45 min into the process (compared to 9 min last time).
I suppose this means i need a new PS? I am going to order the MSI - MPG A850G today. but if anyone has reasons why not to get this one Im all ears.
i am budgeting for 12 spinners, this PS has a single rail with 70 Amps available, more than enough and useful up to 15, which is my case's ultimate capacity.
Could this issue be tied to any other possible root cause?

Update. The rebuild has paused again after 9 minutes, the disk is again disabled. I havent replaced the power cable, but its the middle connector on a 3-connector unit directly from the power supply (no splitter). the other two disks are fine.
Here is an updated diagnostics. I'd appreciate advice on this one. repository-diagnostics-20240808-1729.zip

Well I am surprised. this drive is attached via my SAS card . i swapped the cable for a spare attached to the LSI card, and the array has begun the rebuild process.
i am confused how that cable could just stop working - its been in place for at least a year, the two cable sets are probably 1.5 yrs old. Is there anything else i should investigate for problems? I should note that i never updated this card to work in IT mode, its been in raid mode for years with no issues. i know i should update this, maybe this is the time after rebuild completes.
if anyone can suggest an idiot's guide thread, i'd appreciate that. i know basically how to do it but i am paranoid about this task.

Thanks again.
i started the procedure, and the disk is immediately disabled by the array with write errors. i have stopped the array and will replace the connector, but if this doesnt work, i suppose i RMA the drive?

Thanks Jorge,
You refer to this procedure, right? So when i unassign disk 11 and restart, there will be data there without a drive? then i reassign disk 11? A little squeamish about this if im honest.

Rebuilding a drive onto itself
There can be cases where it is determined that the reason a disk was disabled is due to an external factor and the disk drive appears to be fine. In such a case you need to take a slightly modified process to cause Unraid to rebuild a 'disabled' drive back onto the same drive.
Stop array
Unassign disabled disk
Start array so the missing disk is registered
Important: If the drive to be rebuilt is a data drive then check that the emulated drive is showing the content you expect to be there as the rebuild process simply makes the physical drive match the emulated one. If this is not the case then you may want to ask in forums for advice on the best way to proceed.
Stop array
Reassign disabled disk
(optional) Tick the box to start in Maintenance mode. If you start the array in Maintenance mode you will need to press the Sync button to trigger the rebuild. The advantage of doing this in Maintenance mode is that nothing else can write to the array while the rebuild is running which maximises speed. The disadvantage is that you cannot use the array in the meantime and until you return to normal mode cannot see what the contents of the disk being rebuilt will look like.
Click Start to initiate the rebuild process and the system will reconstruct the contents of the emulated disk.
This process can be used for both data and parity drives that have been disabled.

I shut down my array about 2 weeks ago to add a new refurbished drive. Rebooted, preclear went fine. My array began its scheduled monthly parity check abt 32 hr ago, and 31 minutes in, disk 11 was disabled by the array. there are a series of read errors in the log, followed strangely by a series of write errors. Disk 11 is an existing array disk and the new disk is not yet in the array.
anyway i would like to rebuild the disk but thought I'd ask for folks to have a look at my logs and help me make sure the disk is ok, or should i do a warranty return. here are the logs and thank you for your help.

fyi. i updated my primary server from 6.8.3 to 6.11.2 using the webtool without issue.
-
I updated my backup server from the GUI from 6.8.3, went smoothly. Main server in a bit after next parity check.
-
tyvm Jorge, and you're right. Ive been avoiding updating, I will follow future release notes.
-
Apologies if this isnt the right place to ask, but i am on 6.8.3. Is there an upgrade path or do i simply do the normal procedure on my usb (back it up, shutdown, copy new files to it, boot server, all smiles)?
-
Done, thanks!

Chiming in, NV,
If i am correct in summarizing your initial post as "I am afraid to use unraid because of the possibility of bitrot"
then my sarcastic thought in reply is that it is similar to thinking "I am afraid to go for a walk outdoors because I am afraid of being struck by lightning/bitten by a cobra/hit by an asteroid"
I am not taking a side on bitrot being a problem or not, but if it is, it is a very low probability problem with a very low file loss rate. I am not even sure it is unique to unraid. You should have a separate physical backup of anything important - something which absolutely has nothing to do with unraid.
Like many, my first unraid array, built in 2011, is still in service as my primary nas. I have a second and my next PC of any type will also be an unraid array (who cares, just mentioning). It is reliable, as cheap as it can be when you have 10's of TB of storage, and its as easy to use as it could be. If you've never maintained a NAS before, you will see that you have a lot to learn no matter which you choose. Like many, I'd recommend unraid but it's your life.
Use unraid or no, but bitrot fear seams a ludicrous reason to avoid unraid.
good luck,
Pete

for my two servers, listed in my sig, here are my numbers:
i7-3770 server, idle (no activity, all disks spun down) is about 60 watts. at 99% processor activity and all drives spun up, it is about 195 watts.
1230L server, idle at about 36 watts. it never sees full activity, but all disks active results in just uner 60 watts.
fwiw, i am sure noone cares

the supermicro server boards are excellent. go to the supermicro website page for that board to identify specific compatible products. the intel website is a good source of information on each compatible processor, its a simple matter of checking those web pages.

If you'll forgive me, your post sounds like an open threat that developers must provide xyz or you will buy something else. If that's not what you're trying to say then you might reword it... if this is what you meant, well, best of luck to you mate.
It seems to me that a second server, providing backup, is a solution. There must be hundreds of ways to use a backup server effectively.

Thanks jb. I think you are implying to then remove the old drive and use the new config to rebuild parity after swapping the disks? Probably a bit less work too.
thanks!

I'm late to the party on this one
I have one ST8000DM004 that I bought because it was cheap. It failed in february with a bunch of udmacrc errors that were not affected by swapping out the cable - last count was 1491 and that was generated after a preclear when i tried to put it into my array and write to it - unraid wrote a few GB and then hundreds of crc errors popped and i had to rebuild my array with the disk it was replacing.
I was able to RMA that drive and i now have a refurbished ST8000DM004 with another year of warranty. I really would like to use it in my array, and from reading here it sounds like I can get the life out of it by rebuilding my smaller disk onto it, then moving data from other disks onto the DM0004 so that no more writes occur to it, and just let it sit and serve data. IIRC i used the original DM004 that failed as my parity disk for a while.
Does anyone like or dislike my strategy? I hate to throw away $250 replacing what should be a perfectly serviceable drive. I'd like to minimize my risk with it.
I am running dual parity, so not that worried about a failed drive if that's what happens.
Thanks for your suggestions on this.

I dont know if there is much differentiation among SATA cables but I use monoprice cables.
Seasonic is the gold standard for power supplies. I think you want at least a 850W PS, though, with that many drives.
-
dont take this the wrong way, mate, but using a NAS commits you to a lifetime of occasional drive purchases. If you need another drive to migrate data, you should just buy the drive. You will use it and need more in the future anyway. Im not being unsympathetic, this is the easiest way and you are going to buy more drives anyway as time goes by.

Not sure where to post, so here it goes: Now that i stopped using the two mb marvell SATA ports, i have only 14, and they are full. I have a new drive that i need to preclear before i add it to my array. Can i do that on the marvell port and then transfer it to another port when i replace a drive?
Im in a bind because my power supply doesnt seem to be able to handle a second 8 port controller, and i dont need 8 more ports anyway.
the new drive is an exchange from an rma - can i assume its good and just swap it in? Seems risky to me...
-
thanks mate, I see Jorge's thread now. This thread should probably be un-stickied as it is obsolete?
-
I don't mean to complain, but the first posti in this thread recommends the Supermicro AOC-SASLP-MV8, which I have, unfortunately. This card can no longer be used in UNRAID and the first post really should be changed to reflect current reality.
Or should one be expected to read all 29 pages of the thread to generate one's own list to sort through?
-
arent LSI _the_ recommended cards? Forgive my ignorance but it is very surprising to read that a common, recommended controller doesnt play nicely with unraid. What's the deal with this?
(I have two LSI cards and _extremely_ happy that I havent yet moved on from 6.8.3, jesus)

As a data point. My primary server is now 10 years old, and I continue to use the same flash drive. Perhaps I should prophylactically upgrade?

The rebuild has completed. I remain surprised by this as this connector is a standard sata power connector, the middle of three, direct from the PS. Ever see this before?
I am replacing the power supply with the one now listed in my sig. got a good deal from newegg on it.
Thank you, Jorge.
