PHP7 + Symfony 3.1.0 + Vagrant：无法写入会话数据

Question

although the path /mnt/my-proj/app/../var/sessions/dev is accessible for both the normal user and www-data I get the following message:

Warning: session_write_close(): Failed to write session data (user). Please verify that the current setting of session.save_path is correct (/mnt/op-accounting2/app/../var/sessions/dev)

I get the message above only in dev, but not in prod. /mnt/my-proj/app/../var/sessions/dev and /mnt/my-proj/app/../var/sessions/prod have the same pemissions: 777.

The path above is mounted as following:

# mount -t vboxsf -o uid=1000,gid=33,umask=000 my-proj /mnt/my-proj;

What am I doing wrong?

I've read the following posts, but could find no solution for me:

PHP7 + Symfony 2.8, Failed to write session data

I'm using Vagrant 1.8.1 on Windows 8.1 Enterprice (64Bit) and ubuntu-xenial 16.04 in Vagrant. The provider is VirtualBox 5.0.20. The settings are mostly default ones. The path above is shared using VirtualBox GUI with full access.

Kind regards,

Juri

SOLVED! :-)

Setting

save_path:   "/var/lib/php/sessions"

in /mnt/my-proj/app/config/config.yml solved the problem. Any adjusting of ini-Files in /etc/php/7.0/ wasn't neccessary (those files have still default values only).

But I wander why didn't I get that error message in prod?
