a recent network interruption has now caused errors with my xen servers connection to an ifs share over iSCSI.

If I reboot the Xen server then everything comes backup, but within 20 mins the /var directory on the linux containers goes into read only because of journal errors

Here is an out put of the errors from the zfs storage box

According to errno.h -1 means insufficient permission.
-32 broken pipe (quite logical once permission is denied)

We resolved the problem.  The network switch was having a problem.  We replaced the switch and all issues have been resolved.  Thanks for you reply.
