All snapshots disappeared + no new snapshots possible

[snooker]

Hello to all,

I am running OS 6.6.1 on a legacy ReadyNAS Pro 2 (with 2 Gig RAM) - up to today without any issues, but now I ran into my first (homemade  😞  ) trouble:

After reading a posting in the Ubiquiti forum, I tried to install the Unifi Controller Software on my ReadyNAS and failed. The installation procedure included Java8 and failed during the install of this package (dpkg error message about missing space). After that I tried to tidy up everything and the NAS seems to work fine - with one - for me suprising - exception:

All my snapshots disappeared (the snapshot count on the shares-pages is 0 for all my shares) and it is not possibe to make new snapshots (automatic snapshot generation does not work and if I try manually I get the error "Failed to create a new snaphot. Code: 2800302001"). But on the Volume view there is still some space allocated for snapshots).

Scrubbing and balancing works fine without errors and the volume is reported to be ok.

Has anybody an idea how to treat this?

Is there a possibilty to reinstall the OS 6.6.1 without loosing all the content on the Volume?

Any idea is highly appeciated!

Best regards

Stephen, thank you for pointing me to the logs!

The Log was flooded with:

Failed to set locale. Fix your system.;

And this was the reason for my snapshot problem. All snapshots were still on the volume, but there was a display problem in FrontView caused by the missing locale..

I fixed the locale with:

locale-gen "en_US.UTF-8"
dpkg-reconfigure locales

After that everything was fine again.

Best regards

How full is the OS partition?

Yes, and the OS partition is fine.

Perhaps PM skywalker or mdgm, and ask them if they are willing to analyze your logs.
