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 osd: 4 osds: 4 up (since 104m), 4 in (since 24h) rbd-mirror: 2 daemons active (2 hosts) rgw: 2 daemons active (2 hosts, 1 zones) data: volumes: 1/1 healthy pools: 13 pools, 481 pgs objects: 231.83k objects, 648 GiB usage: 1.3 TiB used, 1.8 TiB / 3.1 TiB avail pgs: 481 active+clean io: client: 1.5 KiB/s rd, 8.6 KiB/s wr, 1 op/s rd, 0 op/s wr Best regards, Eugenio Tampieri
