Yes. That's what I did. I do include the lvmcfg module. I use raid1, then I specify that the raid1 volume is to be used as a physical volume for LVM. But I suspect something is wrong with the way my hard disks are set up, and it's interfering with the installation -- as if it is reading inconsistent information from a previous LVM installation. I have previously istalled partitions with the i386 sarge, and the AMD64 sarge. I followed instructions on the web -- well after installation -- about setting up the RAID1 and the LVM. They seemed to work fine until I rebooted. I suspect I did not do something right, because when I tried changing the LVM setup it would complain there were two logical volumes with the same name. My guess it that it had recognised the logical volumes *before* recognising RAID (in fact, it may never had recognised the RAID), and, of course, both hda3 and hdb3 (which I have now moved physically to hdc3) had identical contents. So now the two partitions making up the RAID may have different and inconsistent LVM partitioning information. Even if I delete the RAID-related partitions, and then reconstruct them, the newly created RAID seems to have LVM stuff already there. But it doesn't appear to be usable. -- hendrik > > Regards > > peter colton > > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe". Trouble?
