TasksPlease note down the drive names of size 2.7T in lsblk output. Example: sdk, sdl, sdm...sdy
Resolution
Please follow the below procedure to add new DAC disks to mapr service.
  1. Login to SAW node as administrator.
  2. Run below commands in sequence.

    maprcli disk add -host <host> -disks /dev/sdk,/dev/sdl,/dev/sdm
    maprcli disk add -host <host> -disks /dev/sdn,/dev/sdo,/dev/sdp
    maprcli disk add -host <host> -disks /dev/sdq,/dev/sdr,/dev/sds
    maprcli disk add -host <host> -disks /dev/sdt,/dev/sdu,/dev/sdv
    maprcli disk add -host <host> -disks /dev/sdw,/dev/sdx,/dev/sdy

    Note: <host> needs to be either localhost or self IP address of SAW node.

  3. Please use below commands to verify disks added successfully to mapr service.

    /opt/mapr/server/mrconfig sp list
    maprcli disk listall|grep -i Mapr


    Sample output:


    /opt/mapr/server/mrconfig sp list output shows new disks added to storage pools.
