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? sunfch@node1 tmp]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 27G 21G 4.5G 82% / tmpfs 940M 88K 940M 1% /dev/shm /dev/vda1 485M 40M 421M 9% /boot /dev/sda 10G 1.9G 8.2G 19% /var/lib/ceph/osd/ceph-0 /dev/sdb 10G 10G 7.3M 100% /var/lib/ceph/osd/ceph-1 /dev/sdc 10G 1.8G 8.3G 18% /var/lib/ceph/osd/ceph-2 /dev/sdd 9.8G 1.9G 7.9G 20% /var/lib/ceph/osd/ceph-3 /dev/sde 9.8G 1.8G 8.0G 19% /var/lib/ceph/osd/ceph-4 /dev/sdf 9.8G 1.8G 8.1G 18% /var/lib/ceph/osd/ceph-5 /dev/sdb 10G 10G 7.3M 100% /mnt/tmp [sunfch@node1 tmp]$ striprados -p chenji -u 300m 300M set up a rados cluster object connected to the rados cluster created an ioctx for our pool created a striper for our pool fail |
