Problem resolved. Probably Unionfs was the cause.
In Docker is base path (/var/lib/docker) an I set it to my data disk via Unionfs (/srv/xxxxx/). When I set it to default (system disk with OS) all is working.
I try set direct_io=disable but had some errors - set it back to enable.
Now I have Docker system files on OS drive and contained data on Data drive (direct path - /media/xxx not via Unionfs)
