How to check allocatable space and license restriction in a Virtuzzo cluster?
pstorage stat output:
[root@vz ~]# pstorage -c clustername stat | head -6 connected to MDS#6 Cluster 'clustername': healthy Space: [OK] allocatable 27.3TB of 57.7TB, free 90.7TB of 173.1TB MDS nodes: 5 of 5, epoch uptime: 5d 18h CS nodes: 216 of 216 (216 avail, 0 inactive, 0 offline) License: ACTIVE (expiration: 09/29/2015, capacity: 47.6TB, used: 27.1TB) Replication: 3 norm, 2 limit
In this example 57.7TB can be used for allocating data chunks with configured replication level, and 47.6TB of space is licensed.
