[Gluster-users] GFIDs not showing up as extended attributes

[Kent Nasveschuk]

OK thanks, I see them now. I wish I could have found somewhere where that was documented, or a post someone made referring to that. 

This all came about because a directory exists from the user view that I wanted to delete. When trying to delete it said "directory not empty" from the user view. On the node side 1 node node still contained data in the directory. I think the directory was added during testing, no sure how. 

(glusterfs mounted on /glusterfs_distribute01 ) 
[root at nas1 ~]# ls /glusterfs_distribute01/IT2/ 

(XFS file syste mounted on each node on distribute01/) 

[root at clus-node1 ~]# ls /distribute01/IT2 
[root at clus-node2 ~]# ls /distribute01/IT2 
[root at clus-node3 ~]# ls /distribute01/IT2 
omero_data 
[root at clus-node4 ~]# ls /distribute01/IT2 

[root at nas1 ~]# rm -Rf /glusterfs_distribute01/IT2 
rm: cannot remove directory `/glusterfs_distribute01/IT2': Directory not empty 


So gluster nodes don't agree on the backend with the directory contents. I attempted rebalance "fix-layout" and rebalance "migrate-data" didn't seem to make a difference with that 1 directory "IT2".

Hi... 

I don't think you will see any gluster-related extended attributes on 
your /glusterfs_distribute01 directory. 

Try to have a look for them on the bricks (cln1:/distribute01). 


On my system I only see extended attributes on the bricks. 
None visible on the glusterfs-mounted directory. Don't think they are 
needed to be visible there, since its the "users" view of the filesystem. 

(I also use XFS on the bricks and 3.2.5) 

Regards,
