Ceph
|
||||
====
|
||||
|
||||
We run Ceph via Rook. The Rook operator is running in the `ceph-rook-system` namespace. To debug Ceph issues, start by looking at its logs.
|
||||
|
||||
The following Ceph clusters are available:
|
||||
|
||||
ceph-waw1
|
||||
---------
|
||||
|
||||
HDDs on bc01n0{1-3}. 3TB total capacity.
|
||||
|
||||
The following storage classes use this cluster:
|
||||
|
||||
- `waw-hdd-redundant-1` - erasure coded 2.1
|
||||
|
||||
A dashboard is available at https://ceph-waw1.hswaw.net/, to get the admin password run:
|
||||
|
||||
kubectl -n ceph-waw1 get secret rook-ceph-dashboard-password -o yaml | grep "password:" | awk '{print $2}' | base64 --decode ; echo

Known Issues
|
||||
============
|
||||
|
||||
After running `nixos-configure switch` on the hosts, the shared host/container CNI plugin directory gets nuked, and pods will fail to schedule on that node (TODO(q3k): error message here). To fix this, restart calico-node pods running on nodes that have this issue. The Calico Node pod will reschedule automatically and fix the CNI plugins directory.
|
||||
|
||||
kubectl -n kube-system get pods -o wide | grep calico-node
|
||||
kubectl -n kube-system delete pod calico-node-XXXX
