I need to migrate a filesystem with 20T in RHEL in GFS2 to Oracle Linux in OCFS2 (OPCC).
This filesystem host more than 18 millions litle files and more than 3 millions changed files per day.
I have a application outage less than 60 hours and I am use rsync to do this copy but differencial rsync takes more than 3 days to finish.
RClone support GFS2 to OCFS2 ?
Can RClone is faster than rsync ?
