Re: about PG_Number

Hi wah peng,
   Just a thought.
If you have a large amount of OSDs but less pg number. You will find your data write unevenly.
Some OSD have no change to write data.
In the other side, pg number too large but OSD number too small that have a chance to cause data lost.



Best wishes,
Mika

Hello,

what's the disadvantage if setup PG_Number too large or too small against OSD number?

Thanks.
