When backing up 1 Windows MA, the file sync is failing trying to create VSS snapshots. Windows event logs report VSS failure with "system reserved" volume. If I turn off backing up the system state for that MA, the backup of the MA filesystem run fine. I've restarted the services, and then the server. Did not make a difference.
This all started coincidently after removing a disk (actually a jbod) from the MA on Monday, and rebooting the server at that time.
Running vssadmin list writers, shows the System Writer and WMI Writer in a failed state.
Again, I can restart the services and/or reboot the machien, and the writers all show as "ok".
They only go into the failed state when I try doing a backup of the MA, which includes saving the system state.
