All transfers are automatic and no special actions are required by the user. Migrated files are listed in the normal directory structure, and are identified by an m in the first field of ls -l output. Once DMF is active, quotas on Yukon will be applied according to the same policies that have been in place on chilkoot since cut-over. Quotas apply to data physically on disk, only. They do not apply to data which have been migrated off-line.
Quotas apply to the data aggregate.
That is, files that remain on disk AND migrated files are counted and the aggregate storage volume is measured against the user's quota. CRL tapes can only be written from chilkoot. Following the reboot of denali on May 17th, any e-mail sent to you at denali will be routed to chilkoot. Any unread denali mail will be moved to chilkoot and made available to you there. See news items on chilkoot for details.
