HI, All: I am new and this is my first time to write an email here, i am very appreciate that i can get your help. I create 3 virtual machines on my personal computer and build a simple test ceph storage platform based on these 3 VMs. The host names are ceph-14(the leader node)、ceph-15 and ceph-16. Each host with 2 data disks(osds) and each data disk with 20 GB. The status of ceph is HEALTH_OK, everything works well.
[root@ceph-14 ~]# rados -p data put object1 helloceph [root@ceph-14 ~]# [root@ceph-14 ~]# rados -p data ls object1 [root@ceph-14 ~]# [root@ceph-14 ~]# cd /var/lib/ceph/osd/ceph-1/current/0.3c_head/ [root@ceph-14 0.3c_head]# ls object1__head_BAC5DEBC__0 [root@ceph-14 0.3c_head]# cat object1__head_BAC5DEBC__0 Hello Ceph, You are Awesome like NJW [root@ceph-14 0.3c_head]# I am very confused that how can i get the object id of object1 above? There are 3 parts of an object: metadata、data and object id. I think i can get data part of object1 from above outputs, but how can i get object id of object1? I searched so much and so long on google, but never get what i want. So i am very appreciate that you can give me a guide here!!! Best Wishes Conan
