* thin arbiter: set notify-contention option to yesAshish Pandey2018-08-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | If this option is "ON' and if there is a lock contention for a file from 2 clients/self-heal daemon, an up call will be sent to all the clients holding that locks. Clients can handle this notification and may release the locks at the right time asap. If this option is ON, we get "instant" lock contention notification on client side. In next version of thin arbiter, we need to implement lock contention notification handling and two domain locking to synchronize update/access of xattrs of thin arbiter replica id file. This option is an efficient way to find out lock contention. In this case it is also helping to implement two domain locking for replica id file.

* thin-arbiter : Provide scripts and service file to start thin-arbiter processAshish Pandey2018-05-303-0/+138
1 - setup-thin-arbiter.sh To setup directory path for thin-arbiter. This is the path where replica id file will be placed and used by TA process. By default it will be /mnt/thin-arbiter. It is better to use default path and once set it should not be changed. 2 - gluster-ta-volume.service This is the Unit file used by systemd to start and keep the thin-arbiter process running. 3 - thin-arbiter.vol This is the default volume file for thin-arbiter. It will be used to start thin-arbiter process. This should not be modified by user except the directory path which can be modified using [1].
