What happened?

To research #950 I built a test setup without k8s, just starting GoToSocial locally and using a NFS share for it's storage. This results in the same error, the storage backend errors out:

$ docker run --rm -v /mnt/nfs/gotosoc-data:/gotosocial/storage -e GTS_HOST="gts.local" -e GTS_ACCOUNT_DOMAIN="gts.local" -e GTS_DB_TYPE="sqlite" -e GTS_DB_ADDRESS=":memory:" -e GTS_LOG_LEVEL="debug" superseriousbusiness/gotosocial:0.5.2

What you expected to happen?

The service to initialize the storage system.

How to reproduce it?

see docker command above. I also ran the gotosocial binary without docker to the same (erroneous) result.

Anything else we need to know?

These are the NFS mount options:

server.local:/export/nfs on /mnt/nfs type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=172.27.32.70,fsc,local_lock=none,addr=172.27.32.80)

This is how the storage directory looks after the crash:

$ ls -al gotosoc-data/
total 1548
drwxrwxrwx   2 user  user     3 Nov 10 10:25 .
drwxr-xr-x 101 user  user   185 Nov 10 10:25 ..
-rw-r--r--   1 nobody nogroup   0 Nov 10 10:25 store.lock

Oh i'm sorry. I closed it as a duplicate but it's not exactly, just caused by the same underlying issue. Feel free to reopen if you like :)

It's fine to close. I just wanted to document findings a bit more, as it's not really related to k8s :)
