Subject: Can't enable writeback
Date: Sat, 17 Aug 2013 22:00:08 +1000 [thread overview]
Message-ID: <520F65C8.8050301@internode.on.net> (raw)
I've installed kernel 3.10.7 on Ubuntu 13.04 amd64, and bcache-tools
from
https://launchpad.net/~mighost/+archive/ppa/+build/4767454/+files/bcache-tools_1.0-1ppa1%7Eraring_amd64.deb.
I can create a bcache volume and mount and use it without any problems
using writethrough (120GB Intel 330 SSD caching a WD 2GB HDD), but when
I try to enable writeback:
sudo echo writeback > /sys/block/bcache0/cache_mode
it returns the error
bash: /sys/block/bcache0/cache_mode: No such file or directory
/sys/block/bcache0 exists as a link:
ls -l /sys/block/bc*
lrwxrwxrwx 1 root root 0 Aug 17 15:58 /sys/block/bcache0 ->
../devices/virtual/block/bcache0
Suggestions on how to enable writeback?
Nick Payne
