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.
I understood. At one point (I forget which update, but it's been a while), Netgear did change from having caching enabled only when an UPS was detected to having it on all the time. Before that time, it was less likely that a sudden power loss would result in a re-sync, and that may account for some of your history with it. But since that change, it's common. You apparently got lucky a lot or just had fewer interruptions, and thus fewer chances.
