→ Applies to: SynetoOS 6.x

 

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

 

Step 2. Get root privileges

sudo su -

 

Step 3. Set ZFS property (replace <synetoos_hostname> with the name of SynetoOS, <pool_name> with the name of the pool and <datastore_uuid> with the UUID of the VM datastore)

zfs set eu:syneto:creation='{"hostname": "<synetoos_hostname>", "poolName": "<pool_name>", "poolGuid": 0, "machineId": "migrated-os5-os6"}' <pool_name>/syn-volumes/<datastore_uuid>

EXAMPLE

zfs set eu:syneto:creation='{"hostname": "syneto-os-replica.domain.local", "poolName": "flash", "poolGuid": 0, "machineId": "migrated-os5-os6"}' flash/syn-volumes/03d23208-0d7e-5434-8fab-8931fc39203a


In this case the path is flash/syn-volumes/03d23208-0d7e-5434-8fab-8931fc39203a

 

Step 4. Set sharenfs to off (replace <pool_name> with the name of the pool and <datastore_uuid> with the UUID of the VM datastore)

zfs set sharenfs=off <pool_name>/syn-volumes/<datastore_uuid>

EXAMPLE

zfs set sharenfs=off flash/syn-volumes/03d23208-0d7e-5434-8fab-8931fc39203a
