Ouch...!
Thanks for the head's up, and is there any workaround for this?
Can i for instance :
1. Create the iscsi block on the primary server with command : zfs
create -p -s -V 10G vol0/iscsi/LUN_10GB
2. Use sbdadm to make the lun available with command : sbdadm
create-lu /dev/zvol/rdsk/vol0/iscsi/LUN_10GB
3. Add a view to this LUN with the command : stmfadm add-view uuid_of_LUN
4. use zfs send/receive to replicate this LUN from the primary server
to the backup server
5. on the backserver use sbdadm create-lu or import-lu
/dev/zvol/rdsk/vol0/iscsi/LUN_10GB
Thanks for all the tips.
