Are there ceph command sequences that could have enabled that flag as a side-effect? Since I cannot thing of anything I did that would have enabled this I am a bit concerned that I might re-enable this without my knowledge in the future. Thank you again for the assistance! -David -- David Prude Systems Administrator PGP Fingerprint: 1DAA 4418 7F7F B8AA F50C 6FDF C294 B58F A286 F847 Democracy Now! www.democracynow.org _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
