[ceph-users] Must host bucket name be the same with hostname ?

Hi all,

    There are SASes & SSDs in my nodes at the same time.
    Now i want divide them into 2 groups, one composed of SASes and one only 
contained SSDs.
    When i configure CRUSH rulesets, segment below:


        # buckets
        host robert-a {
        id -2           # do not change unnecessarily
        # weight 1.640
        alg straw
        hash 0  # rjenkins1
        item osd.0 weight 0.250    #SAS
        item osd.1 weight 0.250    #SAS
        item osd.2 weight 0.250    #SSD
        item osd.3 weight 0.250    #SSD

        }


    So, i am not sure must host bucket name be the same with hostname.


    Or host bucket name does no matter?



Best regards,

Xiucai
