Using deadline I/O Scheduler for Ubuntu 16.04 Server
Hi DigitalOcean Support Team,
Since your servers use an SSD drive i would like to use the deadline I/O scheduler.
lsblk shows me, that the main drive is vda
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 253:0 0 160G 0 disk ├─vda1 253:1 0 159.9G 0 part / ├─vda14 253:14 0 4M 0 part └─vda15 253:15 0 106M 0 part /boot/efi vdb 253:16 0 444K 1 disk
I checked the currently used scheduler for the vda using
sudo cat /sys/block/vda/queue/scheduler
, what showed me “none” as current scheduler
I can not modify this file to use another scheduler.
What do I have to do, in order to use deadline as scheduler ?
