[Gluster-devel] about afr

[nicolas prochazka]

Hi,
I'm tryning to set
option transport-timeout 5
in protocol/client

so a max of 10 seconds before restoring gluster in normal situation ?
no success, i always in the same situation, a 'ls /mnt/gluster'   not
respond after > 10 mins
I can not reuse glustermount exept kill glusterfs process.

Regards
Nicolas Prochazka
