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 ?
