Hi,

I want to mirror root hard disk in SUSE LINUX 10.1.

I have two 80G hard disks, I searched in google but I did not find any good link to describe this.

Please see below info..
Code:



Server1:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 16G 1.2G 14G 8% /
udev 1.3G 140K 1.3G 1% /dev
/dev/sda7 59G 33M 59G 1% /home
Server1:~ # sfdisk -d /dev/sda
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
# partition table of /dev/sda

Please help me, I am new to SUSElinux and please give me helpful links.

If you Googled for this, you must not have tried very hard. Typing in "linux mirror drives" gives over 3 million hits.

Also, you don't tell us about your hardware configuration, and what kind of 'mirror' you want. Want to mirror boot partition? Just data? Can your hardware controller support hardware RAID1? What have you done/tried thus far???

Hi,
I want to mirror every thing that is on disk.
I have two hard disks each of 80GB.
I am now testing the procedure.
I have to replicate the same in a production server.

I searched again in google, I can find links for RHEL root mirroring but for SUSE, I dont find any.
Please help me

Thanks
Srini

I asked in my first reply about your hardware configuration, i.e. controller, version/distro of Linux, etc. Saying "SUSE" tells us very little. Again, do you want the ENTIRE disk (boot partition and everything), or just data? Mirroring boot volumes is difficult, and the procedure is different. Pay attention to what people ask you, if you'd like replies.

Again, searching for "suse volume mirroring", brings up over 130K hits, so if you did Google for it, you must not have tried very hard. If all you're talking about is setting up an LVM, you can easily boot from the SUSE CD, run yast, and set it up.

Ok Leave that google thing for now.
If you are right,I am not able to understand in google.
Thanks for replying.
I do not have any controllers(or I dont know).
All I want to do is mirror everything that is on my first disk to second disk.

Thanks
Srini

If you don't have a controller, how do you think your hard drives are plugged in right now?? You STILL tell us nothing about your hardware, version of SuSE, etc. If you won't give details or pay attention, then there's little we can do for you.

Pick one of the guides you found on Google, follow it, and post specific questions/problems if you get them.
