I created a storage volume(eg: test) from a storage pool(eg:vg10) using
the following command:"virsh vol-create-as --pool vg10 --name test --capacity
300M."
When I re-executed the above command, the output was as the following:
"error: Failed to create vol test
error: Storage volume not found: storage vol 'test' already exists"
I think the output "Storage volume not found" is not appropriate. Because in
fact storage
vol test has been found at this time. And then I think virErrorNumber should
includes
VIR_ERR_STORAGE_EXIST which can also be used elsewhere. So I make this patch.
The result
is as following:
"error: Failed to create vol test
error: storage volume 'test' exists already"
