[opensuse] How to clone HDD
Dear list, I need to clone HDD that contain OpenSuSE 11.1 with ReiserFS format. AFAIK, Norton ghost is unable cloning ReiserFS. Is it any software that able to do it? Do I need to (re)configure GRUB on copy HDD? Thx & Rgds, Wong -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hello Wong, yes, you can use dd to make a raw copy of a disk or a partition like this: dd if=/dev/sdx of=backup-sdx To speed up the copy, you'll probably want to specify a blocksize with bs=nnnn /Per -- Per Jessen, Zürich (9.4°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not if when done you will be replacing the original with the clone. -- The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 1 Corinthians 7:3 NIV Team OS/2 ** Reg.

Does any of the latter-day disk-by-id stuff affect how you prepare a cloned disk nowadays? Cheers, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hello all, I really don't know if this approach could works on ReiserFS too, but on my ext3, it worked flawlessly: http://forums.opensuse.org/applications/412379-cloning-resizing-disk-my-appr...

Not as long as both disks are not in the system at the same time as either are used to boot from or have partitions mounted by label or UUID. If the clone is to be an additional disk, then among other things you'll have duplicate UUID and/or label problems until you change UUIDs and/or labels on one of the disks. Tidying up Grub files and boot sectors on the clone may also be necessary according to what its partitions are used for. -- The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 1 Corinthians 7:3 NIV Team OS/2 ** Reg.

What you said here is one of my concerns. Seems OpenSuSE (perhaps also other distro) uses Disk ID and "Kudzu like" feature. Would you give advise how to solve this issue?

Thanks to all.
Yes, I want my 2nd (backup) HDD will able to replace the live one (not
online backup). So I will not lose too much time to recover downtime.
Thx & Rgds,
Wong

Note if you want to use the previously cloned disk to make a newer backup for reserve that you must somehow first wipe its partition table prior to booting the openSUSE OS on the original. If you don't, you stand to be copying from the old backup over the current, which would be very bad for your data. One way you might avoid a problem in this regard would be to mount the target via USB (or possibly eSATA?) only after finishing a normal boot. -- The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 1 Corinthians 7:3 NIV Team OS/2 ** Reg.

Hi Felix. My SuSE contain no data it runs just as Internet gateway. I only need a fast cure when HDD crash. I want to make sure (I think it should work) that I can clone the HDD and replace the crashed one, then system will restored. I have ever cloned HDD (but it was EXT2), and I should do some thing with GRUB. Now, I am facing with ReiserFS that I never did it yet.

True cloning is done with sectors only, and knows nothing about filesystems. e.g. if you use dd to clone the whole hard disk, then dd just copies all sectors from one disk to the other exactly. If you are unsure, just try it, then shutdown, substitute the clone for the original, and try boot and see if you can tell if anything has changed. It shouldn't have. I do most of my cloning using a shareware partitioning program called DFSee, which can be run while booted to DOS, or Windows, or OS/2, or Linux, or Max OS X. Run under DOS most operations are slower, but often in rescue mode it can be tough to get anything else to boot at all, while DOS is easily booted from any old bootable floppy disk, including one with DFSee already on it. -- The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 1 Corinthians 7:3 NIV Team OS/2 ** Reg.
