iSCSI + NFS + VDI 3.3.15

Errors reported

1. From client system (VDI side) in the console, we can see the following message when we try to clone a desktop.

[...]
"Error cloning: Sharing of volume 1e945698-3589-4ea7-b75d-1b341f0f79ec failed on storage server 10.34.3.81."

Cause

There might be a memory issue due to DDT (zfs dedup) on appliance side.

Solution

A) From VDI side: restart VDA services on each node. To restart the VDA services, use the command:

bash-3.00# /opt/SUNWvda/sbin/vda-service restart

B) From NAS storage side :Reboot NAS

FROM CLI:
maintenance -> system -> reboot
