Schedules for Thin-Provisioning
You can create schedules to perform thin-provisioning operations at regular intervals. ASM/ME notifies you when scheduled
operations complete or fail.
● You can specify how often the operation occurs—Using a schedule is suggested for volumes on operating systems that do
not perform their on-demand thin-provisioning.
● Dell recommends using a schedule that thin-provisions the volume once a week. You can increase the frequency to daily,
ideally during the time of day when the volume is under the lowest workload.
● For volumes on operating systems that perform on-demand thin-provisioning, you do not need to create a schedule.
However, you can perform a one-time thin-provisioning operation. For example, perform this operation on volumes that were
created on previous versions of the operating system that did not support thin-provisioning. Thereafter, the operating
system’s own thin-provisioning operations keep the volumes sufficiently thin.
● To thin-provision a volume, the file system creates a temporary file in the volume that uses a percentage of the available
free space, unmaps the space occupied by the temporary file, then deletes the file. By default, the temporary file uses 95%
of the free space in the volume. You can reduce this value if the volume is being heavily used to avoid an out-of-space error
during the thin-provisioning operation.
