I'm attempting to detach a a caching device.
However it's not working, the bcache device stays dirty.
# pwd
/sys/block/bcache0/bcache
# cat cache_mode state dirty_data writeback_running writeback_rate
writethrough writeback writearound [none]
dirty
2.0M
1
512
# cat writeback_rate_debug
rate: 512/sec
dirty: 2.0M
target: 3.2G
proportional: -3.2M
derivative: 0
change: -3.2M/sec
next io: 0ms
I'm going to leave the machine on so I can extract any information you need.
(dmesg contains no errors)
Kind regards,
Killian De Volder
