We can only say that device-mapper is being used somehow. It could be LVM, EVMS2, dmraid, or a few other things. Use dmsetup (info,ls,status,targets) as well as the sysfs block slave entries on dm-* to figure it out from scratch. (or at a higher level, try the LVM tools etc). --=20 Robin Hugh Johnson Gentoo Linux Developer E-Mail : robbat2@gentoo.org GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85 --1yeeQ81UyVL57Vl7 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6-ecc01.6 (GNU/Linux) Comment: Robbat2 @ Orbis-Terrarum Networks - The text below is a digital signature.
