Environment

VMware vCenter Server 6.x
VMware vCenter Server 7.x

Cause

Snapshot of mdb file which is taken at location  /storage/db/vmware-vmdir/snapshot is corrupted.

Resolution

If the primary data.mdb file located at /storage/db/vmware-vmdir is intact, you can attempt the following steps:

• Stop all services:

  • service-control --stop --all

• Move all the files in /storage/db/vmware-vmdir/snapshot to a backup location:

  • mv /storage/db/vmware-vmdir/snapshot/* /tmp

• Start all services:

  • service-control --start --all

If the main data.mdb file is healthy, the above steps should allow the services to start successfully and automatically generate a new snapshot file based on the main database.
