To obtain the value, run the "show quota_tree general" command.

quota_tree_name=? Indicates the quota tree name.

The value contains 1 to 127 characters, only including letters, digits, spaces, and special characters (!\"#&%$'()*+-.;<=>?@[]^_`{|}~). On the CLI, the following characters need to be represented with escape sequences: "\|" indicates "|", "\\" indicates "\", "\q" indicates "?", and "\s" indicates a space.

The value can be "on" (enabled quota) or "off" (disabled quota).

  • Change the name of quota tree 0@1 to newqtree.

    admin:/>change quota_tree general quota_tree_id=0@1 quota_tree_name=newqtree
    Command executed successfully.
  • Disable the quota function of quota tree 0@1.

    admin:/>change quota_tree general quota_tree_id=0@1 quota_switch=off
    Command executed successfully.
  • Change the security style of the quota tree whose ID is 0@1 to "NTFS".

    WARNING: You are about to perform a switchover between the NTFS security style and another security style in the specified quota tree. Before performing this operation, note the following:
    1. When the quota switch is enabled, if you perform a switchover between the NTFS security style and another security style, all files and directories under the quota tree will be scanned again. As a result, the quota switch is changed to the Initializing state, and the quota function does not take effect until its state is changed to Enabled.
    2. The time required for scanning is subject to the number of files and directories under the quota tree and the system workload, including the workload on the CPU, memory, and disks.
    Suggestion: Before performing this operation, ensure that it is necessary to perform a security style switchover on the quota tree.
