Comment # 2 on bug 1171895 from Michael Andres

The filesystem behaves pretty strange. Never seen something like this.

The start of the 1st command. The /var/cache/zypp/raw/repo-oss cache directoy
is missing, so we create an empty one.

No cached metadata, so we refresh. All data are downloaded to a temp directiory
(repo-ossridqj8). At the end temp directory and metadata directory are
exchanged. The temp directory (containing now the old metadata) is removed.

So far. so good.

But a few seconds later, the metadata are not present anymore. Again we
download to a temp directory (repo-ossi8Ukya) and exchange the directories.
This time removing the temp directory (containing now the old metadata) fails.
Errno 39 `Directory not empty`. 

This should not happen. As there was no error removing any files inside,
someone had to create new file there.

And a few seconds later the same again, with Temp directory repo-ossm5N2ya.

Interestingly the next command, where the testcase is created, find the 2
orphaned tempdirs (repo-ossi8Ukya and repo-ossm5N2ya) and is able to remove
them.

The original metadata dir however /var/cache/zypp/raw/repo-oss still does not
contain cache data. And so on....


@Radu Ierimie: 
(all commands executed as root) 
If possible, please run a forced refresh and capture the log:

> # rm /tmp/zypper.1171895.log in case it exists.
> ZYPP_LOGFILE=/tmp/zypper.1171895.log zypper ref -f

Then wait ~30 seconds and capture the zypper cache content:

> find /var/cache/zypp/ -ls >/tmp/zypper.1171895.find

Then do another refresh capturing the log in the above logfile

> ZYPP_LOGFILE=/tmp/zypper.1171895.log zypper ref -f



If the issue persist (e.g. 'zypper se -s --not-installed-only' does not find
any packages), please attach the 2 tmp/zypper.1171895.* files.
