CF Card wear optimalisation for ext4
...e devices writes a lot of IO
(is there a tool that can give me some useful numbers for say 24H or a
week? iotop, atop, sysstat doesn?t seem suited for long term IO write
monitoring, but maybe I am misusing them and can use some help here)
I mount root with the following options:
/dev/disk/by-uuid/09a04c01-64c6-4600-9e22-525667bda3e3 on / type ext4
(rw,noatime,user_xattr,barrier=1,data=ordered)
# dumpe2fs /dev/sda1

Are there kernel options to avoid synchronous disk writes? As
suggested here: http://www.pcengines.ch/cfwear.htm
Is there a list of other kernel...
