### Status 2021-06-07
Today I have updated the ceph cluster definition in rook to
* check hosts every 10 minutes instead of 60m for new disks
* use IPv6 instead of IPv6
The succesful ceph -s output:
[20:42] server47.place7:~/ungleich-k8s/rook# kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- ceph -s
cluster:
id: 049110d9-9368-4750-b3d3-6ca9a80553d7
health: HEALTH_WARN
mons are allowing insecure global_id reclaim
services:
mon: 3 daemons, quorum a,b,d (age 75m)
mgr: a(active, since 74m), standbys: b
osd: 6 osds: 6 up (since 43m), 6 in (since 44m)
data:
pools: 2 pools, 33 pgs
objects: 6 objects, 34 B
usage: 37 MiB used, 45 GiB / 45 GiB avail
pgs: 33 active+clean
The result is a working ceph clusters with RBD support. I also applied
the cephfs manifest, however RWX volumes (readwritemany) are not yet
spinning up. It seems that test [helm charts](https://artifacthub.io/)
often require RWX instead of RWO (readwriteonce) access.
Also the ceph dashboard does not come up, even though it is
configured:
