Description Yaniv Kaul 2019-12-15 09:39:44 UTC

Description of problem:
We should strive not to upgrade while we are near full capacity, as during the upgrade we might run out of capacity.
We can set it at 90% or 95% or whatnot, but still - very high capacity and running out of space at this point is a bit dangerous.

The idea is to block it when Ansible runs the upgrade.

Ritesh, can this be added as a pre-check to the ansible upgrade role?

Comment 6 Ritesh Chikatwar 2020-01-27 12:25:59 UTC

Sahina, Yes this is possible i will make changes accordingly.

Comment 8 SATHEESARAN 2020-07-15 19:07:27 UTC

Verified with RHV manager version 4.4.1, when the used space of the storage domain is above 90%, upgrade cluster 
initiated from RHV Manager UI fails with error "Cluster Default upgrade failed. Host disk is running low space on gluster volume(s): vmstore."
