Verify that a mounted NFS share is still operational after failover.
|
|
|
|
We mount an NFS share from a node, write a file via NFS and then
|
|
confirm that we can correctly read the file 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. Mount the selected NFS share.
|
|
5. Create a file in the NFS mount and calculate its checksum.
|
|
6. Kill CTDB on the selected node.
|
|
7. Read the file and calculate its checksum.
|
|
8. Compare the checksums.
|
|
|
|
Expected results:
|
|
|
|
* When a node is disabled the public address fails over and it is
|
|
possible to correctly read a file over NFS. The checksums should be
|
|
the same before and after.
