Obtaining Ceph Installation and Configuration Information

1. Run the lsblk command on the servers to obtain the drive letter names and drive sizes.

   1

   lsblk

   • As shown in the figure below, the data drive letters are "sda", "sdb", "sdc", "sdd", "sde", "sdf", "sdg", "sdh", "sdi", "sdk", and "sdl", and the drive size is 3.7 TB. When setting installation parameters in the ceph_input file (in Setting Installation Parameters), convert 3.7 TB to 3700 GB.
   • Obtain information about the SSDs that need to be used as DB and WAL drives. The drive letters are nvme0n1 and nvme1n1, and the drive size is 2.9 TB. When setting installation parameters in the ceph_input file (in Setting Installation Parameters), convert 2.9 TB to 2900 GB.
     

     

     If you do not need to configure DB and WAL disks separately, skip the corresponding steps.

2. Obtain the names of the NICs for which the service network needs to be configured on a node.
