[Gluster-devel] Re: Multiple AFR instances on same storage bricks

[Krishna Srinivas]

Sam,

If all the clients connect to the same AFR on a server then it works fine.

If there are different AFRs that are accessing same posix/storage volumes
then there is a bug which is not handled (creating a file simultaneously
on two clients might return success on both the clients or locking from
two clients might return success on both the clients) this bug is being
fixed after which you can have multiple AFR instances, but if this bug
does not bother you then you can use multiple AFR instances.
