I'm kind of surprised Claude got all of this so wrong. One of the most basic things is that rebuild will result in the same filesystem as the original.

Release notes have: Is that at all related to this other problem?

Do you have a current flash backup? Also, your logs are full of container(s) restarting. Check the uptime of your containers on the Docker page to see where the problem is. And you have this problem: https://forums.unraid.net/topic/200823-docker-images-loosing-icon-and-then-log-filesystem-fills-to-100-and-then-crashes/

The emulated disk was repaired, but it still needs to rebuild the repaired contents to the physical disk. Since repair resulted in some lost+found, it might be worth seeing if the physical disk can be mounted with Unassigned Devices and decide if the physical contents are better than the repaired emulated disk contents.

Emulated disk9 is mounted and showing plenty of contents. You can rebuild to the same disk. https://docs.unraid.net/unraid-os/using-unraid-to/manage-storage/array/replacing-disks-in-array/#re-enabling-a-disabled-disk-rebuilding-onto-itself

SMART report for disabled disk9 looks fine. I would be surprised if it doesn't pass extended test, but let it complete. 10TB will take a while. Then start the array in normal (not maintenance) mode so we can make sure emulated disk9 is still mounted. Then post new diagnostics.

Also post new diagnostics

Depending on the extent of the corruptioin, filesystem repair may not be able to get the names of some files/folders, or which folder a file belongs in. Those are the files/folders it puts in lost+found. On the User Shares page, click on Compute... for the lost+found share, wait for the results, and post a screenshot.

post new diagnostics

You can access the current documentation from the "manual" link at bottom right of any page of your Unraid webUI. There is also a link to the current documentation at the top of any forum page. I don't see a SMART report for disabled disk9, but the emulated disk9 is mounted and showing plenty of data. If disk9 is connected now post new diagnostics.

SSDs in the array cannot be trimmed and can only be written at parity speed. SSDs belong in pools outside the parity array.

Does old server have any pools?

Check filesystem on disk1

Did you reboot after the Windows repair? Were those diagnostics taken after that? Several segfaults in syslog. Have you done memtest recently?

Will the new server have any drives before you take those from the old server? Probably make more sense to delay this part until after the old drives are in place since the old drives will already have user shares on them.

https://docs.unraid.net/unraid-os/troubleshooting/diagnostics/capture-diagnostics-and-logs/#enabling-the-syslog-server Follow the instructions for Local syslog server

Can't tell anything about which disks may be unmountable because the array wasn't started when the diagnostics were taken. Start the array in normal (not maintenance) mode and post new diagnostics.

Do you mean BIOS doesn't see drive at all, or it just won't boot from it?

Unraid is already immutable. The installed version isn't modified since it is loaded fresh into RAM from archives on the boot device at each boot. Internal boot device is counted as a drive. If you use a drive much larger than needed for the boot device, it can be partitioned into boot and pool partitions, then the pool partition can be used for other things like cache, dockers, ...

actually came from the parity calculation by reading all other array drives including parity. Parity by itself has none of your data. While you could technically format the 10TB as an Unassigned Device, might as well wait until after it is assigned during New Config. Assign new 10TB when doing New Config, then format it after starting the array. You can do the format during or after parity build.

Might be good to disable Docker in Settings until things are working well You need to clean this up anyway Sep 25 08:00:39 unRAIDVM root: Fix Common Problems: Warning: Share appdata set to cache-only, but files / folders exist on the arrayAnd your system share is on the array so that needs to be cleaned up too.

Nothing can move or delete open files so you have to go to Settings and disable Docker and disable VM Manager before you can work with those shares.

Single parity should be enough for so few array drives. You have some FCP errors and warnings you need to take care of: Sep 24 18:16:24 WOODOMUR root: Fix Common Problems: Warning: Deprecated plugin ca.mover.tuning.plg Sep 24 18:16:26 WOODOMUR root: Fix Common Problems: Error: Invalid folder cache contained within /mnt Sep 24 18:16:31 WOODOMUR root: Fix Common Problems: Warning: Share docker set to use pool cachepool, but files / folders exist on the cachhe pool Sep 24 18:16:31 WOODOMUR root: Fix Common Problems: Warning: Share system set to use pool cachepool, but files / folders exist on the cachhe poolYou should probably remove mover tuning at least until you get the other things taken care of. That version is too out-of-date to upgrade anyway. The invalid folder cache is a serious problem so it is flagged as an error. You don't have a pool named cache, instead it is named cachhe. But something is writing to the path /mnt/cache, probably some container host mapping. Since that path isn't actual storage, it is a path in rootfs, the RAM reserved for the OS. Since it is RAM, anything stored there won't survive reboot. And if you fill up that space by writing to it, it can cause problems for the OS since it will have no space to work with. The docker and system shares need to be on one pool or the other. Possibly you have duplicates you will need to clean up.
