Just to clarify as i'm planning to put gluster in production (after fixing some issue, but for this I need community help): corruption happens only in this cases: - volume with shard enabled AND - rebalance operation In any other cases, corruption should not happen (or at least is not known to happen) So, what If I have to replace a failed brick/disks ? Will this trigger a rebalance and then corruption? rebalance, is only needed when you have to expend a volume, ie by adding more bricks ? 2017-10-05 13:55 GMT+02:00 Nithya Balachandran <nbalacha at redhat.com>:> > > On 4 October 2017 at 23:34, WK <wkmail at bneit.com> wrote: >> >> Just so I know. >> >> Is it correct to assume that this corruption issue is ONLY involved if you >> are doing rebalancing with sharding enabled. >> >> So if I am not doing rebalancing I should be fine? > > > That is correct. > >> >> -bill >> >> >> >> On 10/3/2017 10:30 PM, Krutika Dhananjay wrote: >> >> >> >> On Wed, Oct 4, 2017 at 10:51 AM, Nithya Balachandran <nbalacha at redhat.com> >> wrote: >>> >>> >>> >>> On 3 October 2017 at 13:27, Gandalf Corvotempesta >>> <gandalf.corvotempesta at gmail.com> wrote: >>>> >>>> Any update about multiple bugs regarding data corruptions with >>>> sharding enabled ? >>>> >>>> Is 3.12.1 ready to be used in production? >>> >>> >>> Most issues have been fixed but there appears to be one more race for >>> which the patch is being worked on. >>> >>> @Krutika, is that correct? >>> >>> >> >> That is my understanding too, yes, in light of the discussion that >> happened at https://bugzilla.redhat.com/show_bug.cgi?id=1465123 >> >> -Krutika >> >>> >>> Thanks, >>> Nithya >>> >>> >>> >>>> >>>> _______________________________________________ >>>> Gluster-users mailing list >>>> Gluster-users at gluster.org >>>> http://lists.gluster.org/mailman/listinfo/gluster-users >>> >>> >> >> >> >> _______________________________________________ >> Gluster-users mailing list >> Gluster-users at gluster.org >> http://lists.gluster.org/mailman/listinfo/gluster-users >> >> >> >> _______________________________________________ >> Gluster-users mailing list >> Gluster-users at gluster.org >> http://lists.gluster.org/mailman/listinfo/gluster-users > > > > _______________________________________________ > Gluster-users mailing list > Gluster-users at gluster.org > http://lists.gluster.org/mailman/listinfo/gluster-users

[Gluster-users] data corruption - any update?

As long as you don't expand the cluster, you are fine. Basically you can add or remove replicas all you want, but you can't add new replica sets. -------------- next part -------------- A non-text attachment was scrubbed...
