Re: CephFS troubleshooting

Hi,

can you share more details? For example the auth caps of your fuse client (ceph auth export client.<fuse_client>) and the exact command that fails? Did it work before?

I just did that on a small test cluster (17.2.7) without an issue.

BTW, the warning "too many PGs per OSD (328 > max 250)" is serious and should be taken care of.

Regards,
Eugen

Hello,
I'm writing to troubleshoot an otherwise functional Ceph quincy cluster that has issues with cephfs. I cannot mount it with ceph-fuse (it gets stuck), and if I mount it with NFS I can list the directories but I cannot read or write anything.
Here's the output of ceph -s
  cluster:
    id:     3b92e270-1dd6-11ee-a738-000c2937f0ec
    health: HEALTH_WARN
            mon ceph-storage-a is low on available space
            1 daemons have recently crashed
            too many PGs per OSD (328 > max 250)

  services:
mon: 5 daemons, quorum ceph-mon-a,ceph-storage-a,ceph-mon-b,ceph-storage-c,ceph-storage-d (age 105m) mgr: ceph-storage-a.ioenwq(active, since 106m), standbys: ceph-mon-a.tiosea
    mds:        1/1 daemons up, 2 standby
