6.5 HP StoreAll OS User Guide

Setting file and directory allocation policies from the CLI
Allocation policy names are case sensitive and must be entered as uppercase letters (for example,
RANDOM).
Set a file allocation policy:
ibrix_fs_tune -f FSNAME {-h HOSTLIST|-g GROUPLIST} -s LVNAMELIST -p POLICY [-S STARTSEGNUM]
The following example sets the ROUNDROBIN policy for files only on the file system ifs1 on file
serving node s1.hp.com, starting at segment ilv1:
ibrix_fs_tune -f ifs1 -h s1.hp.com -p ROUNDROBIN -s ilv1
Set a directory allocation policy:
Include the -R option to specify that the command is for a directory.
ibrix_fs_tune -f FSNAME {-h HOSTLIST|-g GROUPLIST} -p POLICY [-S STARTSEGNUM] [-R]
The following example sets the ROUNDROBIN directory allocation policy on the file system ifs1
for file serving node s1.hp.com, starting at segment ilv1:
ibrix_fs_tune -f ifs1 -h s1.hp.com -p ROUNDROBIN -R
Setting segment preferences
There are two ways to prefer segments for file serving nodes, StoreAll clients, or hostgroups:
• Prefer a pool of segments for the hosts to use.
• Prefer a single segment for files created by a specific user or group on the clients.
