Hi,
I have deploy a small ceph cluster on my computer,and do a test like below
Firstly ,I make the /dev/sdb full manually by put a 8.3GB file on /mnt/tmp ,and then try to write a 300M file through striprados which is a ceph client using libradosstriper. The result is this write failed.
So,Does ceph has any way to make full use of the left space of other disks in this case?
