I want to confirm I have the expected behavior of LUN usage from a host perspective in a thin provisioned environment.
Assumptions:
- LUN is thin provisioned with no fractional reserve, no volume guarantees
- No snapshots present
My lun used on the storage system will continue to grow until it reaches 100%. The host side will see usage based on filesystem usage (i.e. when a file is deleted space will become available).
The storage system lun usage will go down if a space reclamation tool - such as SnapDrive - is enabled, otherwise the lun usage will stay at 100%.
Is this correct?
