Vertica is a database cluster used for "big data" https://goo.gl/1PgM0a
From system administrator's point of view, it's a shared-nothing cluster running on linux.
We have installed a 3 node cluster on sles, configured a backup job with VMTools quiescence disabled. It seems that the brief stun during snapshot creation/removal is not tolerated from che Vertica cluster, which shuts down itself.
Naturally the best approach is to reduce the impact of the snapshot on VMs (i.e. upgrading from ESXi5.5 to 6.x, and implementing Storage Snapshot integretion on Veeam), but it's possible that even after the best tuning, the Vertica Cluster will remain "too sensitive". So it will probably necessary to implement a script to put the DB in halted state before backup and restart it later.
Has someone here experience with this particular product?
Thanks in advance.
