The main change is to source cluster.bash instead of integration.bash. While touching the preamble, the following additional changes are also made: * Drop test_info() definition and replace it with a comment The use of test_info() is pointless. * Drop call to ctdb_test_check_real_cluster() cluster.bash now does this. * Drop call to cluster_is_healthy() This is a holdover from when the previous test would restart daemons to get things ready for a test. There was also a bug where going into recovery during the restart would sometimes cause the cluster to become unhealthy. If we really need something like this then we can add it to ctdb_test_init().

# 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.
