CEpH simple operation

In the previous article, we introduced the use of CEpH-deploy to deploy the CEpH cluster. Next we will briefly introduce the CEpH operations.

1. Block device usage (RBD)

   A. Create a user ID and a keyring

   CEpH auth get-or-create client. node01 OSD 'Allow * 'mon 'Allow * '> node01.keyring

   B. Copy the keyring to node01.

   SCP node01.keyring [email protected]:/root/

   C. Create an image

   Apt-Get install CEpH-common

   RBD create disk1 -- size 10000-N client. node01-M mon01-k/root/node01.keyring

   RBD map disk1-N client. node01-P mypool-M 10.0.7.177-k/root/node01keyring

   D. Format disk1

   Mkfs. ext4/dev/RBD/disk1

   E. mount a disk

   Mkdir/mnt/disk1

   Mount/dev/RBD/disk1/mnt/disk1
