AFR self-heal bug with rmdir (Directory not empty)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
