		<summary type="html">&lt;p&gt;&amp;quot;==RBD Yaratma=== Deneme pool’u içinde 3.000.000 MByte’lık bir rbd oluşturalım.  rbd create data --size 3000 000 --pool deneme ==RBD Bilgi Alma (RBD in...&amp;quot; içeriğiyle yeni sayfa oluşturdu&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Yeni sayfa&lt;/b&gt;&lt;/p&gt;&lt;div&gt;==RBD Yaratma===&lt;br /&gt;
Deneme pool’u içinde 3.000.000 MByte’lık bir rbd oluşturalım.&lt;br /&gt;
 rbd create data --size 3000 000 --pool deneme&lt;br /&gt;
==RBD Bilgi Alma (RBD info)==&lt;br /&gt;
Pool içindeki rbd’ları görmek için rbd ls komutunu kullanıyoruz:&lt;br /&gt;
 root@cephm:/home/ceph# rbd  ls deneme&lt;br /&gt;
 data&lt;br /&gt;
Daha ayrıntılı bir bilgi almak isterseniz:&lt;br /&gt;
 root@cephm:/home/ceph# rbd --image data -p deneme info&lt;br /&gt;
 rbd image 'data':&lt;br /&gt;
     size 2929 GB in 750000 objects&lt;br /&gt;
     order 22 (4096 kB objects)&lt;br /&gt;
     block_name_prefix: rb.0.99d69.2ae8944a&lt;br /&gt;
     format: 1&lt;br /&gt;
==RBD İstemcilere  MAP Edilmesi==&lt;br /&gt;
Deneme altında yarattığımız data rbd’ı kullanmadan önce istemciye map etmemiz gerekiyor bunun için:&lt;br /&gt;
&lt;br /&gt;
 root@client:~# rbd map data --pool deneme --name client.admin&lt;br /&gt;
 /dev/rbd1&lt;br /&gt;
&lt;br /&gt;
==İstemcilere MAP edilen RBD’lerin Görüntülenmesi==&lt;br /&gt;
Map edilen rbd’lerin görüntülenmesi için rbd showmapped komutu kullanabilir.&lt;br /&gt;
&lt;br /&gt;
 root@client:~# rbd showmapped&lt;br /&gt;
 id pool   image snap device    &lt;br /&gt;
 1  deneme data  -    /dev/rbd1&lt;br /&gt;
&lt;br /&gt;
==İstemcilere MAP edilen RBD’lerin Unmap Edilmesi==&lt;br /&gt;
İlk olarak map ettiğiniz rbd mount edilmiş ise umount etmelisiniz. Ardından rbd unmapped komut ile map edilen rbd’yi kaldırabilirsiniz.&lt;br /&gt;
 root@client:~# rbd unmap /dev/rbd1&lt;br /&gt;
&lt;br /&gt;
==RBD Silinmesi==&lt;br /&gt;
RBD silmek için rbd’nin herhangi bir istemci tarafından map edilmediğine emin olun. Herhangi bir istemciye map edilmiş bir rbd’yi silmek isterseniz aşağıdaki hatayı alırsınız.&lt;br /&gt;
 root@cephm:~# rbd rm deneme/data&lt;br /&gt;
 2015-04-27 15:25:42.573852 7f2a9ac5f840 -1 librbd: image has watchers - not removing&lt;br /&gt;
 Removing image: 0% complete...failed.&lt;br /&gt;
 rbd: error: image still has watchers&lt;br /&gt;
 This means the image is still open or the client using it crashed. Try again after closing/unmapping it or waiting 30s for the &lt;br /&gt;
 crashed client to timeout.&lt;br /&gt;
Bu durumda silmei için ilk olarak hangi istemcinin rbd’yi map ettiğine bakalım.&lt;br /&gt;
 root@cephm:/home/ceph# rados listwatchers --pool deneme data.rbd&lt;br /&gt;
 watcher=172.16.2.106:0/3585843564 client.630175 cookie=1&lt;br /&gt;
İstemciden rbd’yi unmap ettikten sonra komutu tekrar çalıştırırsak:&lt;/div&gt;</summary>
