Goal

How to export a replicated filesystem as ReadOnly without Clone usage

Solution

Replicated filesystems can be exported read-only to NAS clients (shares cannot be exported read/write).

Replicated filesystems are not exported by default. They are exported by modifying the "exported" property of the project or share using the BUI or CLI:

BUI:

Export property

CLI:

v-ss7310a-n0-sca11:shares Proj-04> show
Properties:
[...snap...]
          default_volblocksize = 8K
               default_volsize = 0
                      exported = true      <===
                     nodestroy = false
                    space_data = 283K
[...snap...]
v-ss7310a-n0-sca11:shares Proj-04>

This property is inherited like other share properties. This property is not shown for local projects and shares because they are always exported.

Additionally, severing replication (which converts the package into a local project) causes the package's shares to become exported.

Replicated LUNs currently cannot be exported. They must be first cloned or the replication package severed in order to export their contents.

Be aware of the following bug:
7040538 NFS clients timeout when replication is exported ( mounted ) on target appliance.

Fixed in: 2011.1.1.0

Workaround: Export(mount) replicated shares individually instead of exporting the replicated project.

The full text can be found on the Amber Road Storage help wiki (top-right corner in the BUI)
