[PVE-User] about ceph server

[alex.lu]

hi,

my test cluster env is:
7 x Dell R720 
disk: 12 x 4TB/dev
no ssd
osd:  7 x 11 = 76
mon:  7 x 1/dev

create ceph cluster from the gui, so very good!  

now,  have some questions:

1. health HEALTH_WARN too few pgs per osd (2 < min 20)? 
this is how to calculate?

2. from forum and code, i see the number of nodes is limited, must be less than 8 nodes.
If have to expand the osd, how to operate? 

This feature can be canceled?

Thanks yours providing such a good way!
