Re: could not fsync file ""pg_wal/xlogtemp.23229"": Input/output error

More disk space now available, but still the error happens and postgres won't start.

I think it could be corrupted shared buffers, as stated on the log messages, and perhaps the corruption goes to disk.

Did you add more disk space?

You won't be able to start PostgreSQL unless you do that.

And no, don't start deleting files in the data directory.

What you can do is move the *complete* data directory to another location
with more disk space and start it there.
