Pod fails with error 19 about synology-csi HOT 1 OPEN

As I failed at this error(failed to get disk format of disk ..... blkid returns invalid output) for these days,
according to issues: #35, problems should be solved but why it keeps happening?
by #47, I make my own image build by the Dockerfile within this repository and fixed a little thing (though I'm not sure why it need to be done like this)
RUN apk add --no-cache e2fsprogs e2fsprogs-extra xfsprogs xfsprogs-extra util-linux iproute2 blkid changed to
RUN apk add --no-cache e2fsprogs e2fsprogs-extra xfsprogs xfsprogs-extra util-linux iproute2 RUN apk add blkid

I make my own image locally with Dockerfile changed, then solved this problem (failed to get disk format & blkid returns invalid output)
