[Gluster-users] Import data from brick

[Alexandros Soumplis]

Hi,

Just tried that with the additional step (after removing the .glusterfs 
dir) of clearing the extended attributes of the existing files. Then 
issued the add-brick command but while the data are in the bricks, they 
have no extended attributes "attached" to them, thus they are 
unavailable to the gluster clients.

I suppose that somehow I should instruct gluster to run through the 
brick folder and files and add appropriate ext attrs.

a.
