failing to move LUN between volumes with NDMPCOPY

Hi guys,

I'm trying to move (actually copy) a LUN from one volume to another volume. However, it keeps failing as shown below.

NDCONN-NETAPP-C1> ndmpcopy -d /vol/VMFS_001/ESXI_BOOT_01 /vol/SAN_BOOT

The destination volume has adequate space.

Any ideas?

This is odd.. can you ndmpcopy the entire volume to volume? Does that fail?

Do you have LUN with the same name on destination volume?

Good point...if the file exists then can use -f to overwrite.

Unfortunately no, the destination volume doesn't have a LUN with the same name.

UPDATE: It turned out, that a qtree had been created, which I didn't notice at all.

When I removed the qtree, the ndmpcopy worked as expected.

Thanks for all your answes
