[Gluster-users] Parallel process hang on gluster volume
Am I alone having this problem ? ----- Mail original ----- De: nico at furyweb.fr ?: "gluster-users" <gluster-users at gluster.org> Envoy?: Vendredi 21 Juin 2019 09:48:47 Objet: [Gluster-users] Parallel process hang on gluster volume I encounterd an issue on production servers using GlusterFS servers 5.1 and clients 4.1.5 when several process write at the same time on a gluster volume. With more than 48 process writes on the volume at the same time, they are blocked in D state (uninterruptible sleep), I guess some volume settings have to be tuned but can't figure out which. The client is using op-version 40100 on this volume Below are volume info, volume settings and ps output on blocked processes. _______________________________________________ Gluster-users mailing list Gluster-users at gluster.org https://lists.gluster.org/mailman/listinfo/gluster-users

[Gluster-users] Parallel process hang on gluster volume
Did you see this behaviour with previous Gluster versions?
