Hi, On a CentOS 7 system with a Jewel 10.2.2 cluster I'm trying to create a pool which fails. Any pool I try to create, with or without a ruleset applied to it fails with this error: "Error ENOMEM: crushtool check failed with -12: failed run crushtool: fork failed: (12) Cannot allocate memory" At first I thought it was a package version mismatch, but it doesn't seem to be the case. There are other commands like 'radosgw-admin' I see fail with -12 error codes as well. Any ideas what might be going on here? The system has roughly 29GB of free memory, so that should be sufficient.
