Hi,
I'm trying to use glusterfs with afr.
My setup have 2 servers and 2 clients. / is mounted with user_xattr.
It seems that if you shutdown a server, remove a directory with one or
more childs, then restart the server, the changes won't be replicated
because rmdir is not recursive in afr-self-heal-entry.c
The bug is affecting 2.0.2 and the current git (and probably all 2.x)
1.3.10 works as excepted.
Here is my test case:
$ bin/clients.sh # launch 2 clients
$ tree mnt/ export/
mnt/
|-- 1
`-- 2
export/
|-- 1
`-- 2
$ mkdir + touch
$ tree mnt/1
mnt/1
|-- dir-empty
|-- dir-with-file
| `-- file
`-- dir-with-subdir
`-- subdir
$ kill server 2
$ rm mnt/1/dir* -rf
$ start server 2
$ tree mnt/
mnt/
|-- 1
`-- 2
$ tree export/
export/
|-- 1
|-- 2
|-- dir-with-file
| `-- file
`-- dir-with-subdir
`-- subdir
