Not sure what could have happened, do you have the diags from the filesystem repair?

Your welcome but that wasn't me

That might have changed since I wrote that FAQ entry, need to test it, but you can always convert to a redundant pool before removing. Not AFAIK.

Backup your flash, re-create it using the USB tool, then restore the config folder.

diags?

See here if you want to check the actual errors: https://forums.unraid.net/topic/86337-are-my-smart-reports-bad/?do=findComment&comment=800888

You need to download it first: Settings -> VM Manager

👍

Does a different flash drive work? You can create a trial one just for testing first.

From de FAQ:

Try booting in safe mode and see if it still crashes, if yes try this to see if it catches something.

That's normal because of the different size devices, see here for more info: https://wiki.unraid.net/Un-Official_UnRAID_Manual#High_Water

If you haven't yet you should run memtest.

What brand of disks? Seagates for example show the actual total values, not just the errors, so any activity will increase them.

Something is not correct there, if the VM is using a virtual NIC by default it's a 10GbE virtual connection, and any traffic doesn't go trough the network, e,g,, this is iperf running on one of my Windows VMs with a virtual NIC: C:\iperf>iperf3 -c 192.168.1.10 Connecting to host 192.168.1.10, port 5201 [ 4] local 192.168.1.6 port 64736 connected to 192.168.1.10 port 5201 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 1.03 GBytes 8.89 Gbits/sec [ 4] 1.00-2.00 sec 1.02 GBytes 8.80 Gbits/sec [ 4] 2.00-3.00 sec 1021 MBytes 8.56 Gbits/sec [ 4] 3.00-4.00 sec 1.08 GBytes 9.24 Gbits/sec [ 4] 4.00-5.00 sec 1.13 GBytes 9.73 Gbits/sec [ 4] 5.00-6.00 sec 1.01 GBytes 8.67 Gbits/sec [ 4] 6.00-7.00 sec 1001 MBytes 8.40 Gbits/sec [ 4] 7.00-8.00 sec 949 MBytes 7.95 Gbits/sec [ 4] 8.00-9.00 sec 1.06 GBytes 9.10 Gbits/sec [ 4] 9.00-10.00 sec 1.12 GBytes 9.59 Gbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth [ 4] 0.00-10.00 sec 10.4 GBytes 8.89 Gbits/sec sender [ 4] 0.00-10.00 sec 10.4 GBytes 8.89 Gbits/sec receiver iperf Done.

It doesn't, this is the problem, all disks have this: Formatted with type 2 protection Just google it and you'll find how to remove it.

Kind of pointless to do a pre-read when the disk has known bad sectors, just go directly for the write then do a post read, bad sectors are reallocated on writes, not on reads, now and before considering putting that disk to use it would be a good idea to run a couple o complete preclear cycles.

The only acceptable result is 0 errors. That's pretty much impossible (without errors on the syslog), either you have a hardware problem or something is assessing a disk outside parity, e.g. by accessing /dev/sdX instead of /dev/mdX

That's good, usually means all data should be there, without lost/partial files.

Yes.

You jus need to fix it somewhere on the chassis, I was using one on a JBOD recently:

Docker image is corrupt, but there are other issues on syslog that suggest a possible hardware issue, I would start with memtest

Yes, that's a possibility, I have a couple of those, and at one time had one of those connected to 32 disks with an expander.

Same as 2nd Gen Ryzen CPUs, models 2xxx (not APUs). Should be.
