Verify that a file created on a node is readable via NFS after a failover.
|
|
|
|
We write a file into an exported directory on a node, mount the NFS
|
|
share from a node, verify that we can read the file via NFS and that
|
|
we can still read it after a failover.
|
|
|
|
Prerequisites:
|
|
|
|
* An active CTDB cluster with at least 2 nodes with public addresses.
|
|
|
|
* Test must be run on a real or virtual cluster rather than against
|
|
local daemons.
|
|
|
|
* Test must not be run from a cluster node.
|
|
|
|
Steps:
|
|
|
|
1. Verify that the cluster is healthy.
|
|
2. Select a public address and its corresponding node.
|
|
3. Select the 1st NFS share exported on the node.
|
|
4. Write a file into exported directory on the node and calculate its
|
|
checksum.
|
|
5. Mount the selected NFS share.
|
|
6. Read the file via the NFS mount and calculate its checksum.
|
|
7. Compare checksums.
|
|
8. Disable the selected node.
|
|
9. Read the file via NFS and calculate its checksum.
|
|
10. Compare the checksums.
|
|
|
|
Expected results:
|
|
|
|
* Checksums for the file on all 3 occasions should be the same.
