Allowing a filesystem to be rolled back without unmounting it sounds unwise, given the potentially confusing effect on any application with a file currently open there.
And if a user can't roll back their home directory filesystem, is that so bad? Presumably they can still access snapshot versions of individual files or even entire directory sub-trees and copy them to their current state if they want to - or whistle up someone else to perform a rollback of their home directory if they really need to. I'm not normally one to advocate protecting users from themselves, but I do think that applications have some rights to believe that there are some guarantees about stability as long as they have a file accessed (and that the system should terminate that access if it can't sustain those guarantees). - bill This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
