volume_writeable Writes and deletes file in Volume and checks if it is writeable
mount_successful Checks if mountpoint exists, returns a bool value 0 or 1


If the following message appears while trying to get some information out of your gluster. Increase scrape interval in prometheus.yml to at least 30s.

Another transaction is in progress for gv_cluster. Please try again after sometime
