[Bug 641816] [NEW] iscsi mounts not restarted after suspend/resume

[PascalCavy]

Public bug reported:

Steps to reproduce
* have an ext4 fs mounted through an iSCSI protocol
* list files there, no problems
* suspend the computer to RAM
* resume the computer

EXPECTED : files accessible on the iSCSI FS

PROBLEM : the FS is still mounted but the files are unaccessible (IO
error)

workaround : 
1. umount /iscsifilesystem
2. mount /iscsifilesystem

example after suspend then resume :

$ LC_ALL=C df /mnt/synology-iscsi/
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdc1            154816504  96783688  50168608  66% /mnt/synology-iscsi

$ LC_ALL=C ls -l /mnt/synology-iscsi/
ls: reading directory /mnt/synology-iscsi/: Input/output error
total 0

$ sudo /etc/init.d/open-iscsi status
 * iscsid is running
 * Current active iSCSI sessions:                                                        tcp: [15] 192.168.0.49:3260,1 iqn.2010-03.synology:vmwarepool1

$ sudo umount /mnt/synology-iscsi
$ LC_ALL=C df /mnt/synology-iscsi/
Filesystem           1K-blocks      Used Available Use% Mounted on

$ sudo mount /mnt/synology-iscsi
$ LC_ALL=C df /mnt/synology-iscsi/
