Hi,
Scenario - 3 servers each with 1 brick of storage on their local disk.
These 3 bricks make up a distributed Gluster volume. This volume is
mounted using the fuse client on all 3 servers so they can all
concurrently access the files stored on the shared filesystem.
As I understand it, Gluster will handle file locking and concurrency
across the 3 nodes. Is that true?
Does gluster also handle the file locking if each of the 3 servers
mounts the gluster volume as NFS (mount -t localhost:/blah /blah) or is
locking then handled by each NFS daemon so it would not lock across the
different servers?
All locking in glusterfs is handled by the locks translator in the brick
processes. No locking is local to a gluster NFS server.
