1. AFS Decommissioning Overview Andy Romero Core Computing Division

2. Project Goal  By May 1, 2016: Eliminate all of the remaining dependencies Fermilab has on the AFS Service.  Why ?  Low capacity, Low performance … high annual maintenance cost  Client software has been hard to support (Window / Mac)  The last straw …. Support is no longer available

3. Remaining Dependencies on AFS  User Home Directories  Non-Home Directory AFS volumes

4. User Home Directories  During late March and throughout most of April we will be migrating batches of user home directories  FROM: The AFS based Unix Home Directory Service  TO: The NAS based Unix Home Directory Service  AFS based Home Directories  Special non-standard, add-on AFS client software required  /afs/fnal.gov/files/home/room3/bob  /afs/fnal.gov/files/home/room1/kjsmith  NAS based Home Directories  Linux : built-in NFS client  MacOS and Windows: built-in SMB client

5. NAS based Unix Home Directory Service Paths (examples)  Supported Linux Clusters (gpcf / fnalu ):  /nashome/b/bob  /nashome/k/kjsmith  Linux Personal Workstations  NFSv4-Krb protocol  Mount homesrv01.fnal.gov:/home AS /nashome  MacOS  Mount: smb://homesrv01.fnal.gov/home-unix  Navigate to your home directory: ( example: b/bob )  Windows  Mount: \\homesrv01\home-unix\\homesrv01\home-unix  Navigate to your home directory: ( example: b\bob )

6. Home Directory Migration (What do you need to do)  Real AFS users  Who  Scientists who actively use Linux based computing facilities  Other people who actively use their AFS home directory  You need to know  exactly when your home directory will be migrated  What to do on your home directory migration day  What to do after you finish watching this overview presentation  Watch the presentations under the link: AFS Home Directory Migration Details on the AFS Migration Web Page: http://computing.fnal.gov/nasan/afs-mig/http://computing.fnal.gov/nasan/afs-mig/

7. Home Directory Migration (What do you need to do)  Former AFS users, Occasional AFS users, Non AFS Users  Who  Someone who has at some time in the past used their AFS home directory  Someone who occasionally uses their AFS home directory for general file storage; but, who does not really depend on it.  Someone who has no idea what AFS is  What you should do  You now know where your AFS home directory content will be migrated to if you ever need it.  Finish watching this presentation

8. Non-Home Directory AFS volumes  /afs/fnal.gov/files/cadwww  /afs/fnal.gov/files/code  /afs/fnal.gov/files/data  /afs/fnal.gov/files/docs  /afs/fnal.gov/files/expwww  /afs/fnal.gov/files/products  /afs/fnal.gov/files/public  /afs/fnal.gov/files/reports  /afs/fnal.gov/files/scratch  /afs/fnal.gov/files/tww  /afs/fnal.gov/files/web  /afs/fnal.gov/files/wwwdocs  /afs/fnal.gov/exp  /afs/fnal.gov/products  /afs/fnal.gov/ups  /afs/fnal.gov/admin  Etc etc etc …..

9. Non-Home Directory AFS volumes  Value of Non-Home Directory AFS volumes  Many meetings with experiment liaisons  Our current opinion: “All Remaining Non-Home Directory AFS volumes that have value have been identified”  Our current opinion could be wrong  If you know of a directory or file in the Fermilab AFS tree that is relevant to a current lab activity, project, process  Simply submit a Service Desk Ticket (ASAP !) … We will work with you and provide a custom migration solution  Sample Ticket  The following path is still actively used: /afs/fnal.gov/files/data/e123  Our Default action for Non-Home Directory AFS volumes  All areas which are not flagged (via service desk ticket) as being relevant to a current activity will be archived  Nothing will be deleted !!  It will be possible to have archived data re-activated if it is needed in the future
