[Gluster-devel] 1.4.0qa19 - readonly filter translator

[Snezhana Bekova]

   Hello,
I've started testing glusterfs version 1.4.0qa19. There is problem  
with readonly filter. When I try to a make write operation on readonly  
brick on a glusterfs client (client side afr), the glustrefs server die.
 
This is from the glusterfs client log messages when mounting readonly volume:
"2008-06-16 17:54:17 C [afr.c:6187:afr_check_xattr_cbk] afr:  
[CRITICAL]: 'client-wks1' doesn't support Extended attribute:  
Read-only file system

[CRITICAL]: 'client-wks2' doesn't support Extended attribute:  
Read-only file system"

   And this is from the glusterfs server log when die:

   Here is a part of the log from glusterfs server that crashed:

The underlying file system is ext3 and there is extended attribute support!
The problem not exist on version 1.3.9.
Can you tell me what is wrong? Maybe it is a bug?

   Thanks,
