Description

it can warn the user

  1. if monitor and osd nodes are co-located
  2. if /var is not a separated partition
  3. if monitors are not deployed in different failure domain
  4. if the OSDs are not deployed in different failure domain, see
  5. make sure the /var of monitor or the OSD data partition is not part of any SAN
  6. if user hosts more than 6 journals per SSD (we suggest a maximum of 6)

this script would help the devops/support guys to avoid some obvious mistakes when deploying a ceph cluster.

1. We will run this script to any of the cluster node and it should return true or false if current node is deployed with recommended configuration or not.
2. If not what is not deployed with recommended configuration like os partitions osd disks etc.

Can we add a warning if more than 6 journals share the same disk?

#7 Updated by Vikhyat Umrao about 8 years ago

One more point we can add here we do not recommend any type of RAID for OSD or Journal disk.
