I am able to manually clone (file) the LUNs using the file clone create command switch -bypass-throttle true but that defeats the purpose of using VSC to mount/unmount my backups for restore operations.
Has anyone hit this problem before and what was the permanent fix for it???
Here is the rub…this clone-create backpressure is expected behavior. ONTAP is going to throttle the number of concurrent clone create operations in order to ensure that we don’t impact the node the volume resides on.
I found out that it isn’t so much the number of concurrent clones. It’s actually a calculation ONTAP does to determine a “maximum split backlog”. So ONTAP basically computes what it would take to sustain a certain level of split throughput for 24 hours. It looks like the ONTAP developers tuned this “maximum split backlog” in ONTAP 9.0. So you might find that ONTAP 9.0 is a bit more forgiving before enacting clone split back pressure limits.
