I have a /shared/www/example.com directory, being set up on a mirrored
glusterfs filesystem (two servers).
I have a /shared/www/example.com/images/ directory there, owned by
root:root.
Now, I want the webserver to be able to write to this directory: simple,
just make the webserver the owner:
server1# chown www-data:www-data images
server1# ls -ld images
drwxr-xr-x 2 www-data www-data 4096 2010-09-14 22:19 images
Let's see what server2 thinks about it:
server2# ls -ld images
drwxr-xr-x 2 root root 4096 2010-09-14 22:19 images
Oops, it's back to root!
Now, what does server1 show?
server1# ls -ld images
drwxr-xr-x 2 root root 4096 2010-09-14 22:19 images
As we can see, it's root again - ownership was reset, although I didn't
use "chown root:root". As a result, the webserver can't upload files
(or, any other process which would need a similar operation), although I
initially did "chown www-data:www-data images" on one of the servers.
I'm using glusterfs 3.0.5 on Ubuntu 10.04.
