glusterd/snapshot : Provide enable/disable option for snapshot auto-delete feature.
This patch provides an interface to enable or disable the auto-delete feature. Syntax : gluster snapshot config auto-delete <enable/disable> DETAILS : 1) When auto-delete feature is disabled, If the the soft-limit is reached then user is given a warning about exceeding soft-limit along with successful snapshot creation message (oldest snapshot is not deleted). And upon reaching hard-limit further snapshot creation is not allowed. Example : ------------------------------------------------------------------ |Case - 1: Upon reaching soft-limit | |Snapshot create : snap successfully created. |Warning : soft-limit of volume (vol) is reached. Snapshot creation |is not possible once hard-limit is reached. | |----------------------------------------------------- |Case - 2: Upon reaching hard-limit | |Snapshot create : snap creation failed. |Error : hard-limit of volume (vol) is reached, Hence it is not |possible to take further snapshots. Please delete few snapshots |of the volume (vol) before taking another snapshot. ------------------------------------------------------------------ 2) When auto-delete feature is enabled, then as soon as the soft-limit is reached the oldest snapshot is deleted for every successful snapshot creation (same as existing method), With this it is made sure that number of snapshot created is not more than snap-max-hard-limit.
