Raid Usage
Our raids are split over Yamato and Musashi. Here is how we use them now.
Yamato

- Research users and projects
- /mnt/raid1
- Research users
- /mnt/raid2
- CVS and SVN
Musashi
- /mnt/raid3
- x
- /mnt/raid4
- Mirror, distfiles, iso's, etc.
Redistributing users across the Raids
To move a user from one raid to another:
- Make sure the user is not logged in anywhere
- Move the files from one raid to another in the appropriate directory for example
- mv /mnt/raid0/home/m/mdeepwel /mnt/raid1/home/m
- Update LDAP with the new root location
- In ou=AutoFS,ou=home.users,cn=username,automountInformation, and update to new location. (using phpldapadmin is fine)
- Restart autofs on any computer or service the user could be using, otherwise they will be able to login, but won't have a home directory.
- If they use the cluster, you must restart autofs on each node, or restart the whole cluster.
- Restart teleport, so they can use ssh/ftp to get their files from off site.
- Update amanda to make sure the new user directory is backed up.
