ReadyNAS OS 6.10.0 (Hotfix 2) - problems after update from 6.9.5
Hi.
A big problem after upgrading from version 6.9.5 to 6.10.0.0 / patch 2).
Until the previous firmware version in case of power loss due to power failure, the NAS restarted without any ...

The NAS will resync if it detects that one of the disks is a bit behind the others (due to missed writes). But when the disks are out of sync, it is also possible to lose data (depending on what writes were missed).
I always recommend a UPS. Lots of data loss stories here start with an unexpected power cut.

Maybe you didn't understand well what I wrote. I have had this NAS for five years and in all this time it had never happened that after a power surge on reboot a resynchronization started. It only happened after updating to firmware 6.10.0: is it just a coincidence? I don't think so.

It is common for the NAS to do a resync after an unexpected power cut.
