Which application is filling memory? If it's a brick (glusterfsd) then stopping and starting a brick ("kill" and "gluster volume start ... force") will not waste cycles re-healing any files that are healthy. Any heals of an individual file that were not complete will be restarted as well as

Features and stability are not mutually exclusive. Sometimes instability is cured by adding a feature. Fixing a bug is not something that's solved better by having more developers work on it. Sometimes fixing one bug exposed a problem elsewhere. Using free open source community projects

Re: [Gluster-users] [Gluster-devel] Feature Request: Lock Volume Settings

IMHO, if a command will result in data loss, fall it. Period. It should never be ok for a filesystem to lose data. If someone wanted to do that with ext or xfs they would have to format. On November 14, 2016 8:15:16 AM PST, Ravishankar N wrote: >On 11/14/2016 05:57
