Data Reverted to a Previous Point in Time After Power Outage

[orztrickster]

I installed TrueNAS Scale on Hyper-V using an eight-disk, 4TB-per-disk raidz3 configuration, with the current data utilization at around 95%. After a power outage on December 6, I discovered that the system’s data had reverted to a previous state. Once power was restored, all data added between October 27 and December 6 had vanished.

Previously, a daily snapshot was scheduled, but now all snapshots and the corresponding data from that period are missing. I have already tried running a zpool scrub, but the data did not return. Has anyone experienced a similar situation, or does anyone have a possible solution?

This is what it looks like in the console.

I wonder if snapshots could be deleted by replication of something else. You might want to check zpool history for something interesting.
