SymptomsTo discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - 7000 Series ZFS Appliances - Resilvering runs for a very long time. - Resilvering reports 100% progress, but does not complete. - Scrub/resilver causes systemic slowdown. ChangesN/ACauseCause: Several related CRs around resilvering performance and status reporting.Bugs include: 6743992 - scrub/resilver causes systemic slowdown 6865084 - When resilver was in progress BUI/CLI became inaccessible 6866277 - Resilver takes longer time when appliance has faulted drive 6880105 - disk resilver hangs 6891824 - 7410 NAS head "continually resilvering" following HDD replacement 6898125 - very poor write performance during resilvering process SolutionSteps to follow:- Upgrade system software to 2010.Q1 or later. Enhancements to resilvering performance were included in this version. If still unsuccessful in completing resilver, pause any scheduled replication or snapshot jobs. After the "100%" mark of the resilver progress, the system is exclusively working on the snapshots. Creating additional snapshots, either directly or via replication, will delay the completion of the resilver. ------------------- Additional Resources: Appliance help under Maintenance:System:Updates for software upgrade procedure and related information.
