Chapter 4 Connectivity Management
4.8 NAS Management
Quota is set for users or groups that are registered in the authentication server. When using this function,
registering the users or groups in the authentication server in advance is necessary.
When using the quota function for the first time after upgrading the controller firmware version from
V10L20 or earlier to V10L21 or later, creating quota information on the file system is required. In this
case, perform the following procedure.
(1) Unmount the target NAS user volume with the "forced nas-fsunmount" ETERNUS CLI command.
(2) Create quota information on the file system with the "start nas-fsck" ETERNUS CLI command.
(3) Remount the target NAS user volume with the "forced nas-fsmount" ETERNUS CLI command.
Refer to "ETERNUS CLI User's Guide" for details about each command.
When inconsistencies in the quota information occur, restore the quota information by executing the
"start nas-fsck" ETERNUS CLI command. Refer to "ETERNUS CLI User's Guide" for details.
This function sets two thresholds (Warning and Limit) for the drive space or the file count.
-
When exceeding the warning threshold
This is a predictive notification and writing to the relevant NAS user volume is not prohibited.
-
When exceeding the limit threshold
Writing to the relevant NAS user volume is prohibited.
A total of four threshold values can be set (two for the drive space and two for the file count) in a single
quota setting information (for each line in the quota target list). However, specifying "0" for all the
thresholds (which includes changing the drive space value to "Not Specified") is not allowed. At least one
threshold must have a valid value.
In each NAS user volume, add a quota setting information to multiple users and groups. Note that the
maximum number of quota setting information that can be added in a single operation (by clicking the
[Add] button on the bottom of the screen) is 100 regardless of the operating environment.
When deleting NAS user volumes, quota setting information assigned to that volume are also deleted at
the same time.
Event notifications for the conditions described below can be sent using the specified method. Refer to
"1.9.1 Setup Event Notification" (page 144)
-
The drive space or the file count has exceeded the threshold
-
The drive space or the file count has returned to a normal state below the threshold value
