Thanks again Stan! >=20 > Now I'm planning to add a fourth raid5 to the linear array. You should have used LVM instead of md linear to join your RAIDs into a sin= gle block device. LVM allows placing a single logical volume over physical exte= nts placed in all sorts of non-contiguous, fragmented, overlapping fashions. You could also transparently migrate portions of those physical extents between physical arrays without even having to unmount the filesystem that you have= on the LV. --=20 With respect, Roman --Sig_/WN9YntZNw+/bfYYLKt=A6Ga Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlG0XUAACgkQTLKSvz+PZwgv3gCdGqyLnRJQhOi9TsBdISRkzrpD h/4An0ZGLBH0Mk5q3dcn1hgRLCBn8LGo =QBTt -----END PGP SIGNATURE----- --Sig_/WN9YntZNw+/bfYYLKt=A6Ga--
