If defragmenting volumes on which shadow copies are enabled, use a cluster (or allocation unit) size of
16 KB or larger during the format. Otherwise defragmentation registers as a change by the S hadow
Copy process. This increase in the number of changes forces Shadow Copy to delete snapshots as
the limit for the cache file is reached.
CAUTION:
Allocation unit size cannot be altered without reformatting the drive. Data on a reformatted drive
cannot be recovered.
For more information about disk defragmentation, read the online help.
Disk quotas
Disk quotas track and control disk space use in volumes.
NOTE:
Tolimitthesizeofafolderorshare,see"Directory quotas"onpage65.
Configure the volumes on the server to perform the following tasks:
• Prevent further disk space use and log an event when a user exceeds a specified disk space limit.
• Log an event when a user excee ds a specified disk space warning level.
When enabling d isk quotas, it is possible to set both the disk quota limit and the disk quota warning
level. The disk quota limit specifies the amount of disk space a user is allowed to use. The warning level
specifies the point at which a user is nearing his or her quota limit. For example, a user's disk quota limit
can be set to 50 megabytes (MB), and the disk quota warning level to 45 MB. In this case, the user
can store no more than 50 MB on the volume. If the user stores more than 45 MB on the volume, the
disk quota system logs a system event.
In addition, it is possible to specify that users can exceed their quota limit. Enabling quotas and not
limiting disk space use is useful to still allow users access to a volume, but track disk space use on a
per-user basis. It is also p ossible to specify whether or not to log an event when users exceed either their
quota warning level or their quota limit.
When enabling disk quotas for a volume, volume usage is automatically tracke d from that point forward,
but existing volume users have no disk quotas applied to them. Apply disk quotas to existing volume
users by adding new quota entries on the Quota E ntries page.
NOTE:
When enabling disk quotas on a volume, any userswithwriteaccesstothevolumewhohavenot
exceeded their quota limit can store data on the volume. The fir st time a user writes data to a
quota-enabled volume, default values for disk space limit and warning level are automatically assigned
by the quota system.
For m ore information about disk quotas, read the online help.
Adding storage
Expansion is the process of ad d ing p hysical disks to an array that has already been con figured.
Extension is the process of adding new storage space to a n existing logical drive on the same array,
usually after the array has b een expanded.
Storage g rowth may occur in three forms:
• Extend una llo cated space from the original lo gical disks or LUNs.
• Alter LU Ns to contain additional storage.
