Hi,
I am trying to follow the below document for developing a translator.
https://github.com/gluster/glusterfs/blob/master/doc/developer-guide/translator-development.md
I've created a replica volume and modified the vol file to include rot-13
translator. Below is the snippet from vol file.
volume myvol-posix
type storage/posix
option volume-id b492191e-77a5-4fc3-9394-49218e36dae2
option directory /brick1/repli
end-volume
volume myvol-rot13
type encryption/rot-13
subvolumes myvol-posix
end-volume
volume myvol-trash
type features/trash
option trash-internal-op off
option brick-path /brick1/repli
option trash-dir .trashcan
subvolumes myvol-rot13
end-volume
...
The writes are getting intercepted by the translator and the file is getting
encrypted. But the reads don't seem to be getting intercepted by the
translator. I tried setting break point in the posix_readv function and attach
the brick daemons to gdb. But posix_readv does not seem to be getting called on
the brick daemon and the read completes on the application side.
Can someone please explain how the reads are getting serviced here without
hitting the posix layer.
Thanks and Regards,
Ram
