Hi,
Ceph version 12.2.13.
Ceph status show ‘Health_Warn’ nearfull osd(s) and pool(s). No data in this nvme class pools and nvme osd’s, completely free. But meta values is so big in nvme osds. Why does meta values on OSDs shows huge disk usage?
$ ceph health detail
HEALTH_WARN 1 nearfull osd(s); 6 pool(s) nearfull
OSD_NEARFULL 1 nearfull osd(s)
osd.49 is near full
POOL_NEARFULL 6 pool(s) nearfull
pool 'VmImages_NVMe_FdChassis_Rp3' is nearfull
pool '.rgw.root' is nearfull
pool 'default.rgw.control' is nearfull
pool 'default.rgw.meta' is nearfull
pool 'default.rgw.log' is nearfull
pool 'default.rgw.buckets.non-ec' is nearfull
