Summary: Session file empty when session-path on NFS mount
Status: Feedback
Type: Bug
Package: Session related
Operating System: Ubuntu 14 LTS
PHP Version: 5.6.6

New Comment:
As noted, this is occurring with CentOS 6.x as well.
I am currently writing log files and other file data to the same location with the same permissions.
PHP is generating the session file, but will not write to it or read from it. (I've tried
manually populating the file with known good session data.)
Moving the session save dir internal to the VM has no issues whatsoever.
Identical user definitions, file and directory permissions are being used in both locations.
When the session save dir is on the host computer, PHP writes an empty session file only. When the
session save dir is internal to the VM, PHP handles sessions completely normally.

I think users who have this problem is using user ID mapping or root squashing
http://manpages.ubuntu.com/manpages/intrepid/man5/exports.5.html
Make sure you are not loosing permission due to ID mapping. Since files handler does not anything
fancy for NFS/etc, if your PHP process has permission, it should not have permission issue.

It seems this is some kind of permission issue, but
Re-Opened because reporter has this issue still.
Those who have this issue, please check session data file owner/group of processes trying to
write/read session data file. i.e. sess_{session_id} in session.save_path. It MUST match and it must
not be root for many setups.

Two separate vagrant VM instances.
1)
CentOS release 6.5 (Final)
PHP 5.6.17
Session save path is shared with host machine via vagrant default sync settings (not NFS, SMB,
RSync, or VirtualBox)
2)
CentOS release 6.7 (Final)
PHP 5.6.17 (Also tested with PHP 7 -- not sure which build, ame problem existed)
Session save path is shared with host machine via vagrant default sync settings (not NFS, SMB,
RSync, or VirtualBox) However, I have also tried this setup using the NFS sync type and it also
failed.

Sorry for the delay, but I couldn't reproduce this on my Fedora23 and CentOS7.
"files" handler is working as it should.
Do you have this issue still? I think you have some kind of permission issue such as you are writing
session data by multiple user IDs. It wouldn't work with multiple user IDs or root ID.
