Shared block not displayed

[nexus]

Problem description:
When each physical machine in the cluster executes multipath -ll and can recognize the LUN, the shared block is not displayed when adding sharedblock primary storage.

Analysis of the cause of the problem:
When adding primary storage, the timeout time for synchronizing shared blocks is 5min by default.
There are too many LUNs mapped by the physical machine in this environment, it is impossible to collect all information within 5 minutes, which causes the timeout when calling and the shared block information cannot be displayed.

Problem handling process:

1. set the timeout time through APISyncCallMessage.
   Execute the following configurations on the (single/dual) management node respectively

cloud-ctl configure api.timeout.syncCallAPI=30m

2. Restart the mn service to take effect.
   Single management node environment

cloud-ctl stop && cloud-ctl start

Dual management node environment

zsha2 stop-node && zsha2 start-node

3. Re-add the sharedblock primary storage and wait for the shared block to be displayed.
