I didn't check details, but I think that this is a result of using
too-new ansible. You can try again with 2.9.13.
Ovirt version:
4.3.10.4-1.el7
# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
Memory available:
#free -m
total used free shared buff/cache available
Mem: 64132 30478 494 145 33158 32961
Swap: 16383 0 16383
Is there a way to ignore this check?
There should be. Assuming you use the CLI (not cockpit), you can try this:
hosted-engine --deploy
--otopi-environment=OVEHOSTED_CORE/memCheckRequirements=bool:False
or
hosted-engine --deploy
--otopi-environment=OVEHOSTED_CORE/checkRequirements=bool:False
Latter will likely skip over a few more requirements, but I didn't check which.
Best regards,
