[Swap parity drive with a current data disk]

but would be good to check my understanding on the procedure.

What would described won't work, you could manually move the data from one of the 3TB disks, then do a new config without it and use it as parity.

picking increasing UDMA CRC error count in SMART.

This is usually a SATA cable problem, replace the SATA cable and see if it stops increasing.

[Unable to format Clear Disks from Proxmox]

Reboot, try again, and if it still fails post the complete diagnostics.

[My first SMART error]

Sorry, though you posted the complete diags.

 

CRC UDMA errors are usually a SATA cable problem, replace the SATA cable and acknowledge the current value, as long as it doesn't keep increasing, the problem is resolved.

[Dealing with unclean shutdowns]

If it's a hardware issue most likely there won't be anything logged, you can start by running memtest or using for example a different PSU.

after 3 months with stable server, the last 2 days started to make reboots!!

If you mean the server is rebooting on its own, that's almost always a hardware problem.

[Flash Backup every 15 minutes]

Maybe you have a script running? Check User Scripts.

[Corrupted system while migrating from reiserfs to new drive]

Still problems with disk2, it may be failing, you can try to swap cables with a different disk as a final check.

[My first SMART error]

Which drive?

[Disabled Drive]

Looks more like a power/connection problem, replace/swap cables and try again.

[Some questions about UnRAID]

Don't recommend using zfs for the array at the moment, since there's a know performance issue with writes, it doesn't affect pools, only the array.

 

Pools can also be used with disk shares, or exclusive shares.

You need to update to latest release for Starter keys to be supported.

I'm curious about what the default setting for RAM allocation is before you added this conf file though.

Look for the existing support thread for that container:

Please post the diagnostics, if you cannot get the full diags post the syslog at least.
 

[Parity check slow after power outage]

There's something writing to disk1.

[Slow Parity Sync - 2-8mb/s]

There appears to be something else reading from disk26, try stopping all other activity.

But that's just a share on my array?

No, because it already exists before array start, so something else is creating that folder.

[Random OOM help needed. And high CPU usage just for fun]

I'm not seeing any OOM error, but IIRC correctly this will trigger FCP:

 

Apr 27 11:17:43 Hal-9000 emhttpd: cmd: /usr/local/emhttp/plugins/user.scripts/showLog.php Out Of Memory Check - Hrly

 

Change that script name

[CSUM Loop2 error]

You have something creating this folder before the array starts:

 

Apr 28 04:40:42 Node emhttpd: error: malloc_share_locations, 7199: Operation not supported (95): getxattr: /mnt/user/CommunityApplicationsAppdataBackup

 

You need to correct that, or the shares won't then work correctly.

[Testing USB drive]

Trial does not prevent later using a paid license.

[[Solved] Parity Device is Disabled]

Diags are after rebooting so we can't see what happened, but SMART looks fine, check/replace/swap cables to rule that out and re-sync parity, and if it happens again save the diags before rebooting.

[New Unraid Server (Key Help)]

Once a key is transferred it cannot be undone, you can use the new flash drive with the old server and start a new trial with a different one.

Server back on, my array is completely different-- my disks were all mixed up and not able to start because somehow the parity disk had been moved to the data disks...???

That suggests a flash drive problem.

Now, my array is in the same config, only the Parity drive is showing as a NEW DEVICE. It's exactly the same drive in the same spot! Am I going to lose everything here? the array doesn't want to start anymore because It's say "Too many wrong and/or missing disks!"

If you have all the original disks assigned to the correct slots, you can do a new config and check "parity is already valid" before array start, then start array and you can try replacing the bad disk again.

as it's not nearly old enough to be failing.

Any hardware can fail at any time, even new one.

Assuming faulty hardware is not the root cause, what else could be causing complete shutdowns with no logging?

If the server shutdowns, vs. crashing or hanging, first suspects would be CPU temp or bad PSU, could also be board related.
