Error during vol copy: read socket received eof

Cause of this problem

The error occurs when the source volume capacity is full (at 100%) and the snap reserve is set to 0 percent.

Solution

Before following the steps below, verify that the source volume is online. The destination volume must be restricted. Increase the size of the source volume. For example, to increase vol size by 100 G, issue the following command:  vol size source_volume +100g  Note: Be sure not to exceed the destination. Use the df command to check. Set the snap reserve of the source volume to 20 percent: snap reserve source_volume 20  The source_volume capacity is now 80 percent. Issue the "vol copy" command: vol copy start -S source_volume destination_volume
