RE: Changing boot partition ACCOMPLISHED, now INIT problem
Hi all, Thanks on all your hints. I accomplished booting to another partition with a backup from the machine that was all wrecked. It was a little tricky. I installed a minimum FreeBSD and created a second slice to restore the other FreeBSD SO and make it bootable. Then I created the filesystem, mounted it and restored the backup to that partition. Afterwards I changed the FSTAB file to reflect the new reality (the partitions are now different) and did a reboot! And voilá, when I pressed F2 key on boot manager It started to boot the FreeBSD of the wrecked machine :) Still after probing all the hardware (CDROM, Ethernet boards fxp0, etc) It showed me the following message: 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... -Original Message- From: Aryeh M.

RE: Changing boot partition - ACCOMPLISHED, now INIT problem :(
Hi all, Thanks on all your hints; it helped me comprehending my problem. I accomplished the restore of a wrecked machine only with a .tar backup from it. The recipe is a little tricky. I installed a minimum FreeBSD on a new machine, during sysintall I created 2 slices (one ad1s1 to the minimum SO and swap and another slice ad1s2 to restore the backup) I set the second slice as bootable (option S in FDISK). Then I created the partitions on the first slice and installed the minimum SO (ad1s1a and ad1s1b for swap). After booting to it with F1 I created the new file system with newfs and mounted in rw mode (ad1s2a). Restored the tar backup to it and changed the FSTAB to the new reality (used the initial swap created on the minimum SO ad1s1b and the new partition as / ad1s2a ). Rebooted and voila it was booting the old FreeBSD SO. Still after probing the hardware (CDROM, FXP0, etc ) It showed me this repeated error: 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... 23:29:19 init: can't exec getty '/usr/libexec/getty' for port ... . I though it was something related with the console, so I rebooted to the initial SO with F1, mounted the partition o see /boot and renamed boot.config Did another reboot and booted to F2 but the problem persists. Do you guys have any clue what might this be and how can I solve it? Is it something related with kernel stuff? I have access to the contents of it if I boot through the minimum SO (F1) Thanks for helping this newbie Best regards to you all Nuno -Original Message- From: Aryeh M.

Bare Metal Recovery FreeBSD How To
Hi all, I am trying to do a Bare Metal Recovery from a FreeBSD 6.0 system to a different Hardware. I have a backup from all partitions of the affected system so I am trying to install a minimum FreeBSD 6.0 in a different hardware which I already have up and running. I created a Swap Partition, a / partition where the minimum system is running, and a third partition /backup in which I will restore the backup through the network. Next step will be to change the boot manager and make it boot through /backup. Do you guys think this is doable? I Think I probably must recompile the kernel after the bare metal recovery because the hardware is different, still do you think it might work? What is your opinion on this? What should be the best approach ? Thanks for reading and Best regards Nuno ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
RE: Bare Metal Recovery FreeBSD How To
Thank you all on responding this mater. Well the situation is the hardware is wrecked! So the only thing that I have is the content of all partitions available. The backup is a tar uncompressed data. So I have the contents in a server. So the objective is to use a completely different hardware but with the same kernel, same configurations, same partitions, etc. In that way, what I thought (but I don't know if it is the proper way) was to install a minimum freeBSD (same version which is 6.0) with the following partitions and booting with F1 option: /dev/ad1s1b noneswapsw 0 0 /dev/ad1s1a / ufs rw 1 1 /dev/ad1s1d /new_rootufs rw 2 2 /dev/ad1s1e /archive ufs rw 2 2 /dev/acd0 /cdrom cd9660 ro,noauto 0 0 Then migrate the partions that I have in my backup / - to partition /new_root (/dev/ad1s1d) at the end this should be changed to /dev/ad1s1a /archive - to partition /archive (/dev/ad1s1e) The idea is to make use of the same swap partition, and of course if all goes OK the partition / of the minimum system is lost when bootManager is changed to boot on /new_root. That is what I have in mind but I am not sure if it will work. I am new to FreeBSD and I am more used to red hat, still I am putting some effort to change that :) Best regards and thanks once again Nuno -Original Message- From: Kevin Kinsey [mailto:[EMAIL PROTECTED] Sent: quarta-feira, 19 de Dezembro de 2007 16:58 To: Nuno Gonçalves Cc: freebsd-questions@freebsd.org Subject: Re: Bare Metal Recovery FreeBSD How To Nuno Gonçalves wrote: I am trying to do a Bare Metal Recovery from a FreeBSD 6.0 system to a different Hardware.

I Think I probably must recompile the kernel after the bare metal recovery because the hardware is different, still do you think it might work? Did the kernel have a lot of customization? A GENERIC kernel should boot on almost anything --- which is why bare metal recovery seems a misnomer to me. If the hard disk survives, I simply stick it in another box and rarely have any difficulties. If it doesn't, I do a minimal install with the desired final slice/partition scheme on the new HDD, and simply restore(8) over the top. What is your opinion on this? What should be the best approach ? Well, I don't know your exact situation, but OOTOMH, the partitioning scheme you mention seems like wasting a disk unless you want the final system to have only /, swap, and /backup. Which could be OK, I guess, but isn't the traditional BSD Right Way(tm). Also, I'd consider installing a newer release than 6.0, and only restoring the important stuff. Again, it depends on your situation.
