ceph troubleshoot

1) start with

ceph health detail

2) OSD_FULL

Ceph prevent writing to a full OSD. By default 'full' is set to 0.95. Temporary solution, set full to 0.97

ceph osd set-full-ratio 0.96

ps: to get more info
1- ceph osd dump | grep full_ratio
2- ceph df

(ref https://docs.ceph.com/en/quincy/rados/operations/health-checks/)

3) POOL_TOO_FEW_PGS

list pools

ceph osd lspools

To allow the cluster to automatically adjust the number of PGs

ceph osd pool set <pool-name> pg_autoscale_mode on

To manually set the number of PGs for the pool to the recommended amount with:

ceph osd pool set <pool-name> pg_num <new-pg-num>

4) BLUESTORE_NO_PER_POOL_OMAP
Stop the osd, repair, then start again:
eg: osd.123

systemctl stop ceph-osd@123
ceph-bluestore-tool repair --path /var/lib/ceph/osd/ceph-123
systemctl start ceph-osd@123
