Issue

Attempting a revert from ONTAP 9.13.1P2 to 9.10.1P fails as seen:

cluster_CLI::*> system node revert-to -node node_01 -check-only true true -version 9.13

Performing revert checks Checking for default images Checking for missing volumes/aggregates Checking for missing volumes/aggregates........ Checking for missing volumes/aggregates.........

Error: command failed: The revert check phase failed. The following issues must be resolved before revert can be completed. The Volume Location Database (VLDB) is inconsistent with WAFL information. Contact support personnel to resolve this issue.

The vreport shows an entry typical of

cluster_CLI::*> debug vreport show aggregate Differences:

Name Reason Attributes -------- ------- --------------------------------------------------- aggr1 Present both in VLDB and WAFL with differences Node Name: node-01 Aggregate UUID: dd02bad5-b444-4810-9999-22b5f71ca668 Aggregate State: online Aggregate Raid Status: raid_dp Aggregate HA Policy: sfo Is Aggregate Root: false Is Composite Aggregate: false Differing Attribute: Volume Count (Try to fix volume differences using vreport for volume, and check again.) WAFL Value: 740 VLDB Value: 739

for every single volume in the cluster.

The verport can be cleaned up, but each time the revert is re-reun, then same issue occurs.
