Dear Team, We have two type to disk in our ceph cluster one is Magnetic disk, another type is SSD. # ceph osd crush class ls [ "hdd", "ssd" ] hdd is normally a bit slower, which is normal. initially ssd was faster read/write. Recently we are facing very slow operation on ssd. Need help to troubleshoot the issue we are using CEPH in our openstack cinder backend Regards, Munna _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
