Hello to you all. I would realy appreciate it if somebody with the appropiate knowledge would take a look at my problem. I have a raid enabled kernel, raid is initialised at boot time, the utils are there etc. raid is not configured/setup. I want a RAID-1 instalation. My linux is installed at /dev/hda Command (m for help): p Disk /dev/hda: 255 heads, 63 sectors, 1650 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 3 24066 83 Linux /dev/hda2 4 1650 13229527+ 5 Extended /dev/hda5 4 743 5944018+ 83 Linux /dev/hda6 744 1483 5944018+ 83 Linux /dev/hda7 1484 1516 265041 83 Linux /dev/hda8 1517 1549 265041 83 Linux /dev/hda9 1550 1650 811251 82 Linux swap from dmesg: Partition check: hda: hda1 hda2 < hda5 hda6 hda7 hda8 hda9 > hdc: hdd: unknown partition table autodetecting RAID arrays autorun ... ... autorun DONE. mount /dev/hda8 on / type ext2 (rw) none on /proc type proc (rw) /dev/hda1 on /boot type ext2 (rw) /dev/hda6 on /home type ext2 (rw) /dev/hda5 on /usr type ext2 (rw) /dev/hda7 on /var type ext2 (rw) Now how do reproduce this on my /dev/hdb? I am hopeless with fdisk I think... Also: from QuickStart.RAID c) run: $ mkraid /etc/raid1.conf This creates the RAID-1 superblocks and *ERASES* both paritions. Might take a long time for big arrays. Be careful, this will *wipe* all the information on your composing devices. This is pretty scary! Can this be solved bij copying the (already used!) mountpoints to a third disk and fiddling a littlebit the /etc/fstab, and placing them back after the succesfull initalisation from raid? Thanx for your attention. Tabe
