Creating a standard volume
Creating a standard volume
Standard volumes can be created on any physical or virtual disk available. You use the same technique regardless of how the disk is presented to the server. This allows you to create standard volumes on a server’s internal disks, on virtual disks in a storage subsystem available to a server, and on virtual iSCSI disks available to a server.
If you add the data deduplication feature to a server, you can enable data deduplication for standard volumes created for that server.
You can create a standard volume by completing the following steps:
1. Start the New Volume Wizard. If you just created a storage space, the New Volume Wizard might start automatically. If it did not, do one of the following:
? On the Disks subnode, all available disks are listed in the Disks panel. Select the disk with which you want to work, and then under Tasks, select New Volume.
? On the Storage Pools subnode, all available virtual disks are listed in the Virtual Disks panel. Select the disk with which you want to work, and then under Tasks, select New Volume.
2. On the Select The Server And Disk page, select the server for which you are provisioning storage, select the disk where the volume should be created, and then click Next. If you just created a storage space and then New Volume Wizard started automatically, the related server and disk are selected automatically and you simply need to click Next.
3. On the Specify The Size Of The Volume page, use the options provided to set the volume size. By default, the volume size is set to the maximum available on the related disk. Click Next.
4. On the Assign To A Drive Letter Or Folder page, specify whether you want to assign a drive letter or path to the volume, and then click Next. You use these options as follows:
? Drive Letter To assign a drive letter, choose this option, and then select an available drive letter in the list provided.
? The Following Folder To assign a drive path, choose this option, and then enter the path to an existing folder on an NTFS drive, or select Browse to search for or create a folder.
? Don’t Assign To A Drive Letter Or Drive Path To create the volume without assigning a drive letter or path, choose this option. You can assign a drive letter or path later if necessary.
5. On the Select File System Settings page, specify how the volume should be formatted by using the following options:
? File System Sets the file system type, such as NTFS or ReFS.
? Allocation Unit Size Sets the cluster size for the file system. This is the basic unit in which disk space is allocated. The default allocation unit size is based on the volume’s size and is set dynamically prior to formatting. To override this feature, you can set the allocation unit size to a specific value.
? Volume Label Sets a text label for the partition. This label is the partition’s volume name.
6. If you elected to create an NTFS volume and added data deduplication to the server, you can enable and configure data deduplication. When you are ready to continue, click Next.
7. After you confirm your selections, click Create. The wizard tracks the progress of the volume creation. When the wizard finishes creating the volume, the View Results page will be updated to reflect this. Review the details to ensure that all phases were completed successfully. If any portion of the configuration failed, note the reason for the failure and take corrective actions as appropriate before repeating this procedure.
8. Click Close.
REAL WORLD In the Registry under HKLMSYSTEMCurrentControlSetControlFileSystem, the NtfsDisableLastAccessUpdate and RefsDisableLastAccessUpdate values control whether NTFS and ReFS update the last-access time stamp on each directory when it lists directories on a volume. If you notice that a busy server with a large number of directories isn’t very responsive when you list directories, this could be because the filesystem log buffer in physical memory is getting filled with time stamp update records. To prevent this, you can set the value to 1. When the value is set to 1, the filesystem does not update the last-access time stamp, and it does not record time stamp updates in the file system log. Otherwise, when the value is set to 0 (the default), the filesystem updates the last-access time stamp on each directory it detects, and it records each time change in the filesystem log.
