After removing a directory with files and creating it again, files sometimes are stuck in half-dead state #4

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.create a directory repodata/ on local drive with some small files in it
2.for i in {1..40}; do echo $i; rm -rf /mnt/s3.cuetools.net/RPMS/repodata ; cp 
-r repodata/ /mnt/s3.cuetools.net/RPMS/ ; done

What is the expected output? What do you see instead?
Expecting only numbers from 1 to 40, but what i get is:

The files gradually fall into half-dead state, where they don't exist for 'ls' 
or 'rm', but do exist for 'cp'.

This only goes away after umount/mount or after a certain amount of time 
(presumably after the cache expires).

s3fuse writes the following to it's log when i try to create such file:

open: path: /RPMS/repodata/filelists.xml.gz
open_file::open_file: opening [RPMS/repodata/filelists.xml.gz] in 
[/tmp/s3fuse.local-vQCPA9].
open_file::init: file [RPMS/repodata/filelists.xml.gz] ready.
object_cache::open_handle: failed to open file [RPMS/repodata/filelists.xml.gz] 
with error -2.
open_file::~open_file: closing temporary file for 
[RPMS/repodata/filelists.xml.gz].

I'm going to close this because despite many, many tests (with enhanced 
logging) I can barely reproduce it and when I do, the trace suggests simply 
that fetching metadata for a recently-deleted file occasionally succeeds. If 
you can find a way to consistently reproduce this error, I'm more than happy to 
look at it again.
