Here is a list of Ceph commands that we tend to use on a regular basis:<\/p>\n
a)Display cluster status:
\n‘ceph -s’<\/p>\n
b)Display running cluster status:
\n‘ceph -w’<\/p>\n
c)Display pool usage stats:
\n‘ceph df’<\/p>\n
d)List pools:
\n‘ceph osd lspools’<\/p>\n
e)Display per pool placement group and replication levels:
\n‘ceph osd dump | grep ‘replicated size’<\/p>\n
f)Set pool placement group sizes:
\n‘ceph osd pool set pool_name pg_num 512’
\n‘ceph osd pool set pool_name pgp_num 512’<\/p>\n
g)Display rbd images in a pool:
\n‘rbd -p pool_name list’<\/p>\n
h)Create rbd snapshot:
\n‘rbd –pool rbd snap create pool_name\/image_name@snap_name’<\/p>\n
i)Display rbd snapshots:
\n‘rbd snap ls pool_name\/image_name’<\/p>\n
j)Display which images are mapped via kernel:
\n‘rbd showmapped’<\/p>\n
k)Get rados statistics:
\n‘rados df’<\/p>\n
l)List pieces of pool using rados:
\n‘rados -p pool_name\u00c2\u00a0 ls’<\/p>\n","protected":false},"excerpt":{"rendered":"
