Hi everyone,

I'm trying to understand whether this is a known UGOS issue before I attempt a factory recovery.

I have a UGREEN DXP2800 running UGOS Pro. After an unexpected power loss, the NAS no longer boots normally.

Here is what I've verified so far:

• BIOS and GRUB are working normally.
• The kernel boots.
• The eMMC filesystem is readable.
• OverlayFS mounts correctly (upper/work directories are accessible).
• The RAID array is healthy.
• LVM detects all logical volumes correctly.
• Data appears intact.
• The USER-DATA overlay is readable, including /etc/fstab and the nas_storage configuration.
• SQLite databases on the eMMC appear valid ("SQLite format 3").

The normal boot ends in Emergency Mode with:

Failed to mount home-Flipado-vol2.mount

Booting with:

systemd.unit=emergency.target

stops earlier, but the root account is locked so I cannot obtain an emergency shell.

I also noticed one warning during boot:

Unknown key 'StanderOutput' ...

(probably unrelated, just mentioning it.)

An interesting point is that the NAS behaves the same even with all HDDs removed, which makes me suspect the issue is in the eMMC / UGOS configuration rather than in the storage pool itself.

Before I reset or reinstall UGOS:

• Has anyone seen this after a power failure?
• Is there a documented way to recover the eMMC without touching the storage pool?
• Is there any maintenance shell or recovery mode that doesn't require the locked root account?

Any ideas would be greatly appreciated.

Thanks!Hi everyone,
