From 916520151e495fae53c467c8667cecf8a3570f0c Mon Sep 17 00:00:00 2001 From: Daniel Kuehn Date: Sun, 27 Oct 2019 13:46:05 +0100 Subject: [PATCH] nixos/ceph: Rename old ceph test and add new multi-node test Rename the old ceph test to ceph-single-node and add a new test ceph-multi-node. The ceph-single-node represents a dev cluster whereas ceph-multi-node is closer to a prod cluster. --- nixos/tests/ceph-multi-node.nix | 231 ++++++++++++++++++ .../tests/{ceph.nix => ceph-single-node.nix} | 0 2 files changed, 231 insertions(+) create mode 100644 nixos/tests/ceph-multi-node.nix rename nixos/tests/{ceph.nix => ceph-single-node.nix} (100%) diff --git a/nixos/tests/ceph-multi-node.nix b/nixos/tests/ceph-multi-node.nix new file mode 100644 index 000000000000..a42d2b87c4a4 --- /dev/null +++ b/nixos/tests/ceph-multi-node.nix @@ -0,0 +1,231 @@ +import ./make-test.nix ({pkgs, lib, ...}: + +let + generateCephConfig = { daemonConfig }: { + enable = true;
