SSD LMV Cache setting
by lcleu from LinuxQuestions.org on (#592FM)
I am trying to set up LVM Cache with CentOS 7 and I created LVM Cache with writeback mode, but I had some problem. The data first write in the fast devices and writeback data to slower devices, LVM Cache runnig few houre, data write to slower devices not fast devices.
In my LVM Cache setting:
cache policy = smq
chunk size = 64K
migration threshold = 65536
Why fast devices cann't write data? Is configation flush fast devices in the LVM Cache didn't setting?
Some help would be very appreciated.
