Jackson Yao updated HDDS-6101:
------------------------------
Description: in our cluster , we put scm db and ratis in different
directories which in different disk partitions. but when bootstraping this
cluster , we found the ozone cluster does not work well because the follower
scm fail to install snapshot. after investigating, we found the db checkpoint
will be downloaded to the directory the same as the ratis log by default. when
replacing the old db, scm will use `files.move` to move the checkpoint to the
db directory. but according to the description of it, When moving a directory
requires that its entries be moved then this method fails (by throwing an
IOException). (was: in our cluster , we put scm db and ratis in different
