OceanStor 9000 V100R001C01 protection level objects

1

The protection level of OceanStor 9000 V100R001C01 can be set for any empty directory in WushanFS. By default, protection levels of all directories are the same as data redundancy ratio (N+2) set in the configuration file during software installation.
After a protection level is set for a directory, the protection level applies to both the directory and its subdirectories. If a directory has multiple parents with different protection levels, the protection level of the directory is subject to that of its nearest parent.
