Ceph MDS stuck pending
I've been trying to get rook-ceph working in my cluster, but have not been able to get it running properly.
If I run "k get cephclusters.ceph.rook.io -n rook-ceph"
I get "Cluster created successfully" but Health reports HEALTH_ERR
If I run "k get pods -n rook-ceph", I can see all the osds and mons running, but the mds shows as Pending
If I run ceph status from the toolbox, it says:
| ceph status
cluster:
id: 5a279646-1b01-49f7-92a6-a37e35c2f190
health: HEALTH_ERR
1 filesystem is offline
1 filesystem is online with fewer MDS than max_mds
1 OSDs or CRUSH {nodes, device-classes} have {NOUP,NODOWN,NOIN,NOOUT} flags set
services:
mon: 3 daemons, quorum a,b,c (age 13h)
mgr: a(active, since 13h), standbys: b
mds: 0/0 daemons up
osd: 4 osds: 4 up (since 13h), 4 in (since 13h)
rgw: 1 daemon active (1 hosts, 1 zones)
data:
volumes: 1/1 healthy
pools: 12 pools, 169 pgs
objects: 375 objects, 478 KiB
usage: 212 MiB used, 400 GiB / 400 GiB avail
pgs: 169 active+clean
Any advice? I haven't been able to find anything (that I can understand) about troubleshooting the mds on the rook documentation. I have building a completely new cluster just for rook-ceph and still get this result. Master node has 2CPU 2GB RAM, worker nodes have 4CPU/8GB RAM with 16GB primary disk and 100GB unallocated disk for ceph
