mdiag -r

Synopsis

mdiag -r [reservationid] [-v] [-w type=<type>]

Overview

The mdiag -r command allows administrators to look at detailed reservation information. It provides the name, type, partition, starttime and endtime, proc and node counts, as well as actual utilization figures. It also provides detailed information about which resources are being used, how many nodes, how much memory, swap, and processors are being associated with each task. Administrators can also view the Access Control Lists for each reservation as well as any flags that may be active in the reservation. The command gathers information from the Moab cache which prevents it from waiting for the scheduler, but the --blocking option can be used to bypass the cache and allow waiting for the scheduler.

The -w flag filters the output according to the type of reservation. The allowable reservation types are Job, and User.
