Anyone actually dealing with a configuration using this for your
data drives? I'm looking for more details on what exactly they are
using for the NFS server, but I have a client reporting that their
pg_xlog directory is *full* of .nfs* files that are 'months old' ...
I'm suspecting that this is some sort of temp file that the NFS
itself is creating, and is safe to just delete, but am wondering if
someone out there knows more definitively ... ?
As I recall, that's a side-effect of deleting files on NFS, because of
the statelessness. If one client has a file open, and another client
deletes it, or two processes on the same client have it open and
deleted respectively, or something on the server... I can't remember
which case it is. But they're renames of files that were "deleted".
If nothing has them open (fstat or lsof or something) they should be
safe to delete (but don't blame me if it blows up!).
This is what I was thinking two (around safeness to delete) ... to be
absolutely certain, doing a quick maintenance shutdown for the postmaster,
remove all .nfs* files and then restarting should be safe too ...
Sound about right?
