Hi list, Short: i just want ask, why i can't do: echo 129 > /sys/class/block/rbdX/queue/nr_requests i.e. why i can't set value greater then 128? Why such a restriction? Long: Usage example: i have slow CEPH HDD based storage and i want it export by iSCSI proxy machine for ESXi cluster If i have so low queue depth, i just worry to get a performance problem because cluster can process request, but HV/VM can't send new request if queue in full state Then i have two solutions make several RBD devices for exporting or increase queue depth. What you think about it? -- Have a nice day, Timofey. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
