management policies execute properly. These restrictions apply only to

 

 

 

managed file systems, not to non-managed (SNFS-only) installations.

 

 

 

 

 

 

• Taking into account all managed file systems, you cannot use more

 

 

 

 

than two unique affinity names. However, these two affinity names

 

 

 

 

can be re-used across file systems.

 

 

 

 

• All data stripe groups must have exactly one affinity association, but

 

 

 

 

several stripe groups can be associated to the same affinity. This

 

 

 

 

restriction does not apply to exclusive metadata or journal stripe

 

 

 

 

groups.

 

 

 

 

• At least one policy class must be created to use the configured

 

 

 

 

affinities.

 

 

 

 

 

 

 

 

 

 

Caution: You must designate at least one data stripe group in each

 

 

 

 

 

managed file system as non-exclusive. If you do not make

 

 

 

 

 

this designation, writing to the area of the file system that

 

 

 

 

 

is not associated with any of the affinities will result in an

 

 

 

 

 

out-of-space error.

 

 

 

 

 

Deleting affinities from a file system configuration after

 

 

 

 

 

the file system has been in use for a while could result in

 

 

 

 

 

abnormal behavior. Contact the Quantum Technical

Performing a Metadata Dump

This procedure replaces any existing metadata dump data for the selected file system, and should be run only if the metadata file has been lost or corrupted.
