Ok. I'll change it to this: # We cannot directly force the filesystem to create the metadata # structures we want; we can only achieve this indirectly by carefully # crafting files and a directory tree. Therefore, we must have exact # control over the layout and device selection of all files created. # Clear the rtinherit flag on the root directory so that files are # always created on the data volume regardless of MKFS_OPTIONS. # We can set the realtime flag when needed. $XFS_IO_PROG -c 'chattr -t' $SCRATCH_MNT --D
