Handling Thin provisioning Capacity Threshold Alerts
*One Line Summary
Handling Thin provisioning Capacity Threshold Alerts
Abstract
With recent advancements in T10 standards, thin provisioned storage LUNs reaching capacity threshold limits will start notifying the Host initiators with check conditions about impending administrative actions.
Such notifications require the administrator to perform a bunch of storage provisioning steps. However the kernel is today not equipped to inform the administrator about these tasks. The situation is even more complex when the LUN is shared across Multiple Host initiators via shared filesystems.
The presentation discusses ways to handle such events in the SCSI, filesystem and application layers and aims to drive consensus in achieving this solution.
