[Gluster-users] About gluster fsck question, thanks
I want to know how glusterfs run fsck, I found some thing about fsck on the internet What happens if a GlusterFS brick crashes? You treat it like any other storage server. The underlying filesystem will run fsck and recover from crash. With journaled file system such as Ext3 or XFS, recovery is much faster and safer. When the brick comes back, glusterfs fixes all the changes on it by its self-heal feature. So this means glusterfs just use the underlying filesystem's fsck, Does glusterfs have it's own fsck? ------------------------------------------------------------------------------------------------------------------------------------- ???????????????????????????????????????? ???????????????????????????????????????? ???????????????????????????????????????? ???

That should be taken care by the filesystem of backend bricks (XFS and ext4). gluster just makes sure that both the bricks of the replica pair are consistent.
