From: Darrick J. Wong <djwong@xxxxxxxxxx> r_blocks is in units of fs blocks, but freertx is in units of realtime extents. Add the missing conversion factor so we don't end up with bogus things like this: Pretend that sda and sdb are both 100T volumes. # mkfs.xfs -f /dev/sda -b -r rtdev=/dev/sdb,extsize=2m # mount /dev/sda /mnt -o rtdev=/dev/sdb # xfs_scrub -dTvn /mnt <snip> Phase 7: Check summary counters. 3.5TiB data used; 99.8TiB realtime data used; 55 inodes used. 2.0GiB data found; 50.0MiB realtime data found; 55 inodes found. 55 inodes counted; 0 inodes checked. We just created the filesystem, the realtime volume should be empty. Signed-off-by: Darrick J.
