# Bug 985074 - Verify stale inode/dentry mappings are cleaned out.
|
|
#
|
|
# This test verifies that an inode/dentry mapping for a file removed via a
|
|
# separate mount point is cleaned up appropriately. We create a file and hard
|
|
# link from client 1. Next we remove the link via client 2. Finally, from client
|
|
# 1 we attempt to rename the original filename to the name of the just removed
|
|
# hard link.
|
|
#
|
|
# If the inode is not unlinked properly, the removed directory entry can resolve
|
|
# to an inode (on the client that never saw the rm) that ends up passed down
|
|
# through the lookup call. If md-cache holds valid metadata on the inode (due to
|
|
# a large timeout value or recent lookup on the valid name), it is tricked into
|
|
# returning a successful lookup that should have returned ENOENT. This manifests
|
|
# as an error from the mv command in the following test sequence because file
|
|
# and file.link resolve to the same file:
|
|
#
|
|
# # mv /mnt/glusterfs/0/file /mnt/glusterfs/0/file.link
|
|
# mv: `/mnt/glusterfs/0/file' and `/mnt/glusterfs/0/file.link' are the same file
|
|
#
