This is almost true for me too. Beside the "vos listvol" (which slowes down the fileserver anyway) for me there is a probably soon upcomming performanc issue with "vos dump" since this is my way to do backup. However, I think a bigger machine layout can do quit a bit. Well, of course, this only a point if you hold a large number of very lively volumes on the partition(s)/server. |_______________________________________________ |OpenAFS-info mailing list |[email protected] |https://lists.openafs.org/mailman/listinfo/openafs-info | Fuer Rueckfragen stehe ich gerne zur Verfuegung, bevorzuge jedoch tele- fonische Kontaktaufnahme ( +49 711 459-3949 oder +49 179 6954907 ).
