Policy for Balancing Capacity

Adding a Share Farm

New-File Placement When All Shares Reach the Free Space

Threshold

If all shares fill up to their maintain-free-space measures, the share farm distributes

each new file to the same share as its parent directory.

Disabling the Free-Space Threshold

You can allow the balance rule to continue placing new files on shares that are close

to filling up. Use the

no form of the maintain-free-space command to disable the

maintaining free space feature.

no maintain-free-space

For example:

prtlndA1k(gbl)# namespace nemed

prtlndA1k(gbl-ns[nemed])# volume /acctShdw

prtlndA1k(gbl-ns-vol[nemed~/acctShdw])# share-farm farm1

prtlndA1k(gbl-ns-vol-sfarm[nemed~/acctShdw~farm1])# no maintain-free-space

prtlndA1k(gbl-ns-vol-sfarm[nemed~/acctShdw~farm1])# ...

Constraining New Files

Some installations may prefer to retain files on the same back-end shares as their

parent directories, at least until it is determined that the files must be auto-migrated to

free up space on the share. From gbl-ns-vol-sfarm mode, you can use the

constrain-files command to keep any new file in the same share as its parent directory:

constrain-files

This is the opposite of the new-file

balance policy described above; if you constrain

new files, you cancel the effects of any

balance command that is in force.

For example:

bstnA6k(gbl)# namespace ns2

bstnA6k(gbl-ns[ns2])# volume /usr

bstnA6k(gbl-ns-vol[ns2~/usr])# share-farm fm4
