If correct, now do the disks have to be exactly the same ? For example = if the primary disk is 2.1GB SCSI and the secondary disk is 4.3GB EIDE = would it matter ?!?! Is there a better/efficient way of doing it, besides installing any Raid = device. Am I missing something ? Thanks for your help.

Hi guys,

I have a question regarding = disk-image/disk-mirroring under=20 FreeBSD-2.2.6. I would like to make an exact image of the root = filesystem disk=20 onto another disk, such that in case of a disk faliure I simply boot = from the=20 mirrored disk without having to do any reconfiguring or restoring=20 etc.

Will the following work:

Go to = single user=20 mode.
Partition the new disk exactly like the = current=20 disk
Mount the new disk at=20 /newdisk
cd /
find . -xdev -print | cpio -pdmuv=20 /newdisk
cd /newdisk
mkdir /proc
run crontab to update the modified files (how=20 ?)

If correct, now do the disks have to = be exactly=20 the same ? For example if the primary disk is 2.1GB SCSI and the = secondary disk=20 is 4.3GB EIDE would it matter ?!?!

Is there a better/efficient way of = doing it,=20 besides installing any Raid device. Am I missing something = ?

Thanks for your help. BTW we are running = FreeBSD-2.2.6 on 4=20 machines so far and are very happy! Great job!!

Best regards,
