Gluster with ext4 problem

[Anton <anton.vazir@xxxxxxxxx>]

Hello,

Just attempted to replace a failed brick (HDD), having EXT3 by the new brick formatted to EXT4, but found that GLUSTER starts, and silently ignore (no errors, nothing expplaining in the logs) presence of the new brick, and replication started only when I have replaced FS to back to EXT3.
Is this something known, or maybe there should be pair of ext3/ext3 , ext4/ext4 bricks for replication to work? Any clue?

Regards,
Anton.
