umount of a CIFS share on a Linux client returns 'target is busy'. lsof/fuser does not show access by Commvault... but as soon as the Simpana services are stopped, umount is possible.
Simpana v11 sp14/15. Any idea why Commvault blocking umount?
Recursive scan selected. Set DisableFileIOMonitor, sSKIP_FS_TO_MONITOR and ignoreFStype did not fixed the issue.
