When creating an image, I see the warnings in ceph.log, but what do they
mean? I am new to ceph. Thanks.

Your PGs are not active+clean, so no I/O is possible.
Are you OSDs running?
$ sudo ceph -s
That should give you more information about what to do.

Thanks. this is the info output, I saw osd is running.
Can you help more? thanks.
root@ceph2:~# ceph -s

You'd have to see why the other daemons are not running, try:
$ ceph osd tree
And start the missing OSDs.
But I have ceph osd rm them. so?
Thanks.

Hi,
I have 135 pgs degraded in the system. How can I remove them?
They are in test environment, all data are not important.
Thanks for the kind helps.

Hi,
I have resolved it by run these:
root@ceph2:~# ceph osd crush rm osd.0
removed item id 0 name 'osd.0' from crush map
root@ceph2:~# ceph osd crush rm osd.1
removed item id 1 name 'osd.1' from crush map
root@ceph2:~# ceph osd crush rm osd.2
removed item id 2 name 'osd.2' from crush map
root@cep
what're the IO throughput (MB/s) for the test cases?
Thanks.
