Not directly relevant for pgbackrest probably, but I noticed that
Alpine comes up in a few reports of failing rm -r on CIFS. I think it
might be because BSD and GNU rm use fts to buffer pathnames in user
space (narrow window), while Alpine uses busybox rm which has a
classic readdir()/unlink() loop:
Yeah, this doesn't affect pgBackRest because we have our own rmtree that
uses snapshots (for the last few years, at least).
As for CIFS, there are lots of reports of this sort of thing from
Linux CIFS clients.
There may be users running Postgres on CIFS but my guess is that is rare
-- at least I have never seen anyone doing it.
I'm more concerned about the report we saw on SUSE/NFS [1]. If that
report is accurate it indicates this may not be something we can just
document and move on from -- unless we are willing to entirely drop
support for NFS.
