[zpool import won't use disk ids anymore]

Unraid always uses the sdX identifiers, since the pool devices are assigned, there's no issue if those change, it will use the new ones.

Currently running xfs_repair -L through the GUI to see if it can be fixed

If it doesn't fix it post the output from that.

[Segregate & Maximize Throughput w/ Multiple Ethernet Ports]

If your hardware allows is it you could just passthrough the 2nd NIC to the VM, if not, you can create a bridge for the second NIC and select that as the network source for the VM.

[i think i messed up removing drive how can i save this]

There are still filesystem issues, that's strange since xfs_repair usually only requires one run, but run it again, since there's no parity, just stop the array and type:

 

xfs_repair -v /dev/sdb1

 

Then post the results from that.

Could the flash drive be an issue?

It's not a common symptom of flash drive issues, but it's a possibility.

[Black Magic Speed Tests Seem to be slower when my Shares are "Exclusive Shares"]

MAC SMB with Samba opens another can of worms, and I don't use Macs so cannot help, but there are some threads here with settings that myy improve SMB performance with Mac, start with this one, you can also search the forum for ore tips:

 

 

[Black Magic Speed Tests Seem to be slower when my Shares are "Exclusive Shares"]

Exclusive shares should never cause a performance degradation, most times it should be faster, or at least the same, don't really trust that as a benchmark, recommend testing with an actual large file transfer using Windows explorer.

These usually mean a flash drive problem, you can try backup and re-formatting first, if issues persist, replace it.

Yep, it should mount.

Do I need to run the same command on the other drive in the pool?

Yep, but only continue if the btrfs signature is also found.

[USB Drive corrupted, no backup, help]

OK, in that case you can rebuild disk1, you can then move any data back there, if you want.

[i think i messed up removing drive how can i save this]

Reboot to clear the logs and post new diags after array start.

[Poential data loss after failed upgrade.]

Type N and Enter to keep the signature, then type write and Enter to write the new partition layout, then post again the output of

btrfs fi show

 

[i think i messed up removing drive how can i save this]

Now start the array in normal mode, the disk should mount, check contents to see if they look OK, also look for a lost+found folder.

[Did someone plug in a mouse and keyboard?]

I don't know since I never used a Dell server, but pretty sure those entries were caused by that.

[Poential data loss after failed upgrade.]

Thanks for the beer money!

 

Regarding the pool devices, we can try to recover the partitions, but it will only work if the controller is showing the same sectors and/or the superblock was not wiped, and I believe both can happen with those controllers when you change mode, but it won't hurt to try, type:

 

sfdisk /dev/sdx

 

then write 2048 and hit enter, post the output of that

hey are running hotter than the other drives and I would occasionally get a warning when the temp hit 46 c.

That should not make the server crash, unfortunately there's nothing relevant logged, this can be some hardware issue, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

[USB Drive corrupted, no backup, help]

Not sure I follow, did you move the data that was on disk1 to another disk(s)?

[Poential data loss after failed upgrade.]

But it's not the same controller you have now correct?
