Hi,
We are looking at how to troubleshoot an issue with Ceph FS on k8s cluster.
This filesystem is provisioned via rook 0.9.2 and have following behavior:
- If ceph fs is mounted on K8S master, then it is writeable
- If ceph fs is mounted as PV to a POD, then we can write a 0-sized file to it,
(or create empty file) but bigger writes do not work.
Following is reported as ceph -s :
# ceph -s
cluster:
id: 18f8d40e-1995-4de4-96dc-e905b097e643
health: HEALTH_OK
services:
mon: 3 daemons, quorum a,b,d
mgr: a(active)
mds: workspace-storage-fs-1/1/1 up {0=workspace-storage-fs-a=up:active}, 1
up:standby-replay
osd: 3 osds: 3 up, 3 in
data:
pools: 3 pools, 300 pgs
objects: 212 objects, 181 MiB
usage: 51 GiB used, 244 GiB / 295 GiB avail
pgs: 300 active+clean
io:
client: 853 B/s rd, 2.7 KiB/s wr, 1 op/s rd, 0 op/s wr
I wonder what can be done for further diagnostics ?
With regards,
Ignat Zapolsky
