Hi all:
Here is the original crushmap, I change the algorithm of host to "tree"
and
set back to ceph cluster. However, when I try to map one imge to
rados block device (RBD), it would hang and no response until I press
ctrl-c.
( rbd map xxxx => then hang)
Is there any wrong in the crushmap? Thanks for help.
