description |
According to AWS docs, using newer instance types that use NVME drivers (c5/m5), the io timeout should be set to maximum (ideally 4294967295).
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/nvme-ebs-volumes.html
It appears this is done for 16.04, but in 18.04 it is the default.
Test done by spinning up an m5.large instance in ap-southeast-2.
Ubuntu 16.04 AMI on AWS (latest AMI - 20180126):
$ cat /sys/module/nvme/parameters/io_timeout
4294967295
$ uname -r
4.4.0-1049-aws
Ubuntu 18.04 AMI on AWS (latest nightly AMI - 20180323):
$ cat /sys/module/nvme_core/parameters/io_timeout
255
$ uname -r
4.15.0-1001-aws
Perhaps as part of the move to nvme_core this got lost. |
