zfs discuss - Nov 2010 - ZFS iscsitgtd & backing store no such file or directory after reboot

Hello,

 

A ZFS VDI related question. I''m exporting an iscsi share from a linux
box which i''m mounting on a Solaris 10 VDI broker and subsequently used
by the desktop providers. This is for a proof of concept. This works
fine under VDI 3.2.1 until i reboot the VDI broker.

 

After the broker reboots, the desktop providers are not able to see the
iscsi share anymore. The disk in the vdi pool and its snapshoot are
present. If i try to re-export the isci disk previously used prior to
the reboot of the VDI broker by the desktop provider using ''zfs set
shareiscsi=on'', i then get  a ''iscsitgtd failed request to
share''

 

I''ve spent a few days on this one and don''t have a clue
despite
googling.
