Hi,
these are my tests and results, complete with kernel and packages versions:
1) Stock CentOS 6.5 x86-64 system (kernel 2.6.32-431.1.2.0.1, cifs-utils
4.8.1-19, samba 3.6.9-167): no problem here, but this kernel does not
have CONFIG_CIFS_FSCACHE, so I can not use it for speeding up read
access;
2) CentOS 6.5 x86-64 with ElRepo updates (kernel 3.10.28-1): here
CONFIG_CIFS_FSCACHE is enabled, but I have the problem described above;
3) Debian 7 amd64 with latest updates (kernel 3.2.54-2, cifs-utils
2:5.5-1): CONFIG_CIFS_FSCACHE is enabled, problem happens;
4) Fedora 20 x86-64 (kernel 3.12.8-300, cifs-utils 6.3-1, samba
4.1.3-2): CONFIG_CIFS_FSCACHE is enabled and problem does _not_ happen,
however this is a client distro and I am not so comfortable to put it
into production.
In all cases, the share was published by a Win2008R2 server.
Continuing in my search, I found this:
https://lists.samba.org/archive/samba-technical/2013-August/094532.html
I can confirm that by forcing the use of CIFS ACL (using the cifsacl
mount options) the problem disappear even on the problematic setups. An
ls -al on the mount folder show 1 or more links. However, I am not sure
if this is a good workaround.
Let me know you opinions.
Regards.
