# On linux operating systems the kernel parameter nvme_core.io_timeout controls
# how long the operating system waits before it considers an IO request to be
# failed. It should be set to 4294967295 or the maximum value that the
# operating system allows.
# /sys/module/nvme_core/parameters/io_timeout
# kernel cmdline parameter nvme_core.io_timeout=4294967295
module.nvme_core.parameters.io_timeout=4294967295

[block:blkpat=nvme:csp=aws]
# On linux operating systems the IO scheduler controls how the operating
# systems interacts with storage volumes like AWS EBS. For optimal performance
# on AWS it should be set to "none".
