Thank you, Sven _______________________________________________ Users mailing list Users@ovirt.org<mailto:Users@ovirt.org> http://lists.ovirt.org/mailman/listinfo/users Hi Sven, Do you have granular entry heal enabled on the volume? If no, there is = a feature called granular entry self-heal which should be enabled with shar= ded volumes to get the benefits. So when a brick goes down and say only 1 i= n those million entries is created/deleted. Self-heal would be done for onl= y that file it won't crawl the entire directory. You can run gluster volume set VOLNAME cluster.granular-entry-heal enab= le / disable command only if the volume is in Created state. If the volume = is in any other state other than Created , for example, Started , Stopped, = and so on, execute gluster volume heal VOLNAME granular-entry-heal enable /= disable command to enable or disable granular-entry-heal option.
