Symptoms

pstorage -c clustername top shows warning for the disk space :

Space: [Warning] allocatable 735GB of 5.3TB, free 15TB of 16TB

Cause

Warning is shown, in case the amount of allocatable free space reaches certain barrier :

  • allocatable space is less than 1G

or

  • allocatable space is less than 20% of total effective(allocatable) space in cluster

This amount of space is considered dangerous, as in case of a failure of some large Chunk Server, the cluster may not get enough space to perform the relocation of chunks, and the cluster will become degraded (with all write operations frozen).

Resolution

Add more disk space to the cluster.
