1. AFS Home Directory Migration Details Andy Romero Core Computing Division

2. User Categories  Active AFS Users  Current Fermilab Employees  Current Fermilab Vistors/Guest Scientists  Non-Personal AFS accounts.. With home directory activity in the last 5 years  Inactive AFS Users  Former Fermilab Employees  Former Fermilab Vistors/Guest Scientists  Non-Personal AFS accounts.. No home directory activity in the last 5 years

3. Active vs Inactive … migration differences  Active AFS users (Polite Migration Mode)  Batches of 200  Migration activity will be coordinated between ( Users, Linux Admins, NAS Admins)  Migration at dates and times well communicated  Inactive AFS users (Fast and Silent Migration Mode)  Batches of 1200  No attempt to coordinate or communicate  Archival of Inactive AFS users … not during this migration

4. When will your home directory be migrated  Get the Migration Day Number from the Active AFS User Migration Map http://computing.fnal.gov/nasan/internal/afs-mig/user-lists/ActiveAFSusers-by-lname.htm  Translate the Migration Day Number to a Calendar Date Using the Migration Day to Calendar Day Map http://computing.fnal.gov/nasan/afs-mig/MigDayNumber-to-CalendarMap.htm http://computing.fnal.gov/nasan/afs-mig/MigDayNumber-to-CalendarMap.htm  Don’t Forget your Migration Date !!  Special Actions (should only be relevant for a few people)  Service Desk Ticket Needed To The Warn the Migration Team If  You have a non-Personal AFS account that is still relevant to a current lab activity  An AFS account (personal or non-personal) was incorrectly categorized as inactive

5. User Actions Before Migration Day  The NAS Home directory volume is already been mounted on  GPCF / GPVM nodes  FNALU nodes  If you currently depend on your AFS home directory when you are logged on to a Linux workstation  You must verify that the new NAS home directory volume homesrv01.fnal.gov:/home Is mounted as /nashome on the workstation  If its not mounted contact your Linux system administrator Mounting Instructions: http://computing.fnal.gov/nasan/afs-mig/Linux-Home-Dir-SysAdmin-Guide.txt http://computing.fnal.gov/nasan/afs-mig/Linux-Home-Dir-SysAdmin-Guide.txt  Do This ASAP !!

6. Migration Day  On your migration day, log off before 9:00AM In general, you do NOT have to stop grid jobs The only way that grid submissions could be affected is if you were specifying the full path of your AFS home directory in the file:// argument of your jobsub_submit command.  At 9:00 AM on your migration day the following actions occur  NAS Admins initiate final file replication  Linux Admins update NIS  After successful file replications and NIS updates, migrated AFS home directories are un- mounted  Downtime approx. 20-40 mins.  Migration Complete email message will be sent out after migration actions are done  Users logon after Migration Complete  Users must fix hard coded references to old AFS home dir (links..scripts etc)  Helpful FixLinks script: /nashome/p/petrillo/bin/FixLinks.sh
