- Getting help
Support for erasure coding in a scale-out file system for an LTR use case over the S3 protocol
Erasure coding support in a scale-out file system for an LTR use case over the S3 protocol is provided as a technical preview feature in this release.
You can create a scale-out file system with an erasure-coded layout for an LTR use case.
For better performance, configure erasure coding without using the EC log.
Veritas Access LTR policies create the erasure-coded buckets for the scale-out file system.
See the Veritas Access Online Help for more information on how to configure LTR policies.
Use the following ObjectAccess> commands for setting the parameters for creating scale-out erasure-coded buckets.
ObjectAccess> set fs_type largefs ecoded 4 2 16k stripe_aligned=yes stripe_tag=disk rotating_parity=yes
Note:
You cannot use erasure coding for a scale-out file system for any other use case other than the LTR use case over the S3 protocol.
See the Veritas Access Command Reference Guide for details on how to set the parameters for a scale-out erasure-coded file system.
