[ovirt-users] The number of LVs on the domain VPLEX_DATA_DOMAIN exceeded 300, you are approaching the limit where performance may degrade.

The 300 is a rule-of-thumb number we benchmarked back in the day, and is
probably quite outdated. In fact, in oVirt 4.1.2, we intend to increase it
to 1000 [1].

If you don't want to wait till then, and you aren't suffering any
performance hits when creating/removing disks/snapshots on this domain, you
can increase it yourself by using the engine-config tool:

[~/ovirt-engine-home/] ./bin/engine-config -s AlertOnNumberOfLVs=1000
