Hello, we have test scaleio cluster of latest  Version: 2.0.12000

Cluster have nodes with RFCache enabled.

And dmesg -T show such errors:

[Wed Feb 22 15:41:14 2017] SFC-cache Error:Read from the source (Hnd 10013) failed with error 1.

[Wed Feb 22 15:41:14 2017] Read from the source /dev/sdg failed with error 1.

[Wed Feb 22 15:41:14 2017] SFC-cache Error:Read from the source (Hnd 10012) failed with error 1.

[Wed Feb 22 15:41:14 2017] Read from the source /dev/sdl failed with error 1.

[Wed Feb 22 15:41:14 2017] SFC-cache Error:Read from the source (Hnd 10012) failed with error 1.

[Wed Feb 22 15:41:14 2017] SFC-cache Error:Read from the source (Hnd 10008) failed with error 1.

If I disable RFcache  dmesg output is like this:

Is it normal or some kind of bug ?
