[Apologies if this has already been sent. My home computer systems seems to be falling around my ears as I have changed all the disks around, and I desperately need to ask the question below and get an answer, so I can rebuild my desktop system, and thus release some disks acting as backup on my server. I was trying to send this via sqwebmail from my home server, but it died in the process and - my ssh session terminated and could not be re-established. I think I have probably run out of disk space, because until I do release the space I am running with a very restricted root filesystem . Until I get home I can't fix it, but I want to ask this question quickly to get answers start me on my way]
... I created a raid array with mdadm, thus mdadm --create=/dev/md0 --level=1 --raid-devices=2 /dev/sd[ab]4 and then turned /dev/md0 into a LVM physical volume, volume group and some logical volumes. This worked great until I rebooted, at which point the start-up scripts failed to recreate the raid array, and I got into tricky problems with duplicate LVM PVs with the same UUID. [and ironically, since I used raid to avoid it, some data loss - although fortunately I DO have backups] Two questions 1) In the Debian world, how do you make raid arrays persistent across reboots? [It appears that Debian does not use raidtools and /etc/raidtab as the linux raid howto says) 2) If I do manage to create the array, what stops vgscan during LVM startup from picking up 3 physical volumes (/dev/md0, /dev/sda4 and /dev/sdb4) with the same UUID and only find /dev/md0? -- [EMAIL PROTECTED] (Sent from work e-mail ) This e-mail and any attachment is for authorised use by the intended recipient(s) only.
