ReadyNAS 316 - Out of memory #26736919

Welcome to the club, although RN104 for us, and even then its not sure its really fixed after factory default.

Reappeared after a month for us after restoring backup on new SW version, see https://community.netgear.com/t5/Using-your-ReadyNAS/Readynas-104-out-of-memory-390-won-t-boot-anymore-in-normal-mode/

Well nearly 57GiB of metadata on an 11TiB volume is  a huge amount of metadata. I have a bit over 14GiB of metadata on a volume with a capacity a little under 22TiB and I have about 1.5x the amount of data on my volume compared with what you have.

When the NAS is configured incorrectly for your use case and you get a huge amount of fragmentation you will run out of memory if you don't deal with the problem. It will take longer and a greater amount of fragmentation than with the 100 series, but it can still happen eventually.

Seeing that it also happened just a month after a factory reset for us, just restoring backup and no data changes anymore after that, no apps, no AV, just daily snapshots enabled, all metadata was purely generated by NAS (only 28 snapshots, which shouldnt contain much delta as there were no changes).

So also dont see what could be configured wrong in this case.

BTW seems I screwed up the link above, should be https://community.netgear.com/t5/Using-your-ReadyNAS/Readynas-104-out-of-memory-390-won-t-boot-anymore-in-normal-mode/m-p/1073225

OOM is a generic error. It can be caused by a variety of different things. Anything that causes the NAS to run out of memory.

The 100 series is very different hardware to the 300 series.
