If there are lots of write IO with flash device, potentially, it has
|
||||
flash wearout problem so that admin needs to design write limitation
|
||||
to guarantee storage health for entire product life.
|
||||
To overcome the concern, zram supports "writeback_limit".
|
||||
The "writeback_limit"'s default value is 0 so that it doesn't limit
|
||||
any writeback. If admin want to measure writeback count in a certain
|
||||
period, he could know it via /sys/block/zram0/bd_stat's 3rd column.

|

To overcome the concern, zram supports "writeback_limit" feature.
|
||||
The "writeback_limit_enable"'s default value is 0 so that it doesn't limit
|
||||
any writeback. IOW, if admin want to apply writeback budget, he should
|
||||
enable writeback_limit_enable via
|
||||
|
||||
$ echo 1 > /sys/block/zramX/writeback_limit_enable
|
||||
|
||||
Once writeback_limit_enable is set, zram doesn't allow any writeback
|
||||
until admin set the budget via /sys/block/zramX/writeback_limit.
|
||||
|
||||
(If admin doesn't enable writeback_limit_enable, writeback_limit's value
|
||||
assigned via /sys/block/zramX/writeback_limit is meaninless.)
|
||||
|
||||
If admin want to limit writeback as per-day 400M, he could do it
|
||||
like below.
|
||||
|
||||
MB_SHIFT=20
|
||||
4K_SHIFT=12
|
||||
echo $((400<<MB_SHIFT>>4K_SHIFT)) > \

||||

|
||||
$ echo $((400<<MB_SHIFT>>4K_SHIFT)) > \
|
||||
/sys/block/zram0/writeback_limit.
|
||||
$ echo 1 > /sys/block/zram0/writeback_limit_enable
|
||||
|
||||
If admin want to allow further write again, he could do it like below
|
||||
If admin want to allow further write again once the bugdet is exausted,
|
||||
he could do it like below
|

|

echo 0 > /sys/block/zram0/writeback_limit
|
||||
$ echo $((400<<MB_SHIFT>>4K_SHIFT)) > \
|
||||
/sys/block/zram0/writeback_limit
|
||||
|
||||
If admin want to see remaining writeback budget since he set,
|
||||
|
||||
cat /sys/block/zram0/writeback_limit
|
||||
$ cat /sys/block/zramX/writeback_limit
|
||||
|

If admin want to disable writeback limit, he could do
|
||||
|
||||
$ echo 0 > /sys/block/zramX/writeback_limit_enable
|
||||
|
||||
The writeback_limit count will reset whenever you reset zram(e.g.,
|
||||
system reboot, echo 1 > /sys/block/zramX/reset) so keeping how many of
|
||||
writeback happened until you reset the zram to allocate extra writeback
|
||||
budget in next setting is user's job.
