As we can specify the size of the partition in Cylinders, MB, GB and E. I would like to know what “E” Stands for as i noticed this in Solaris 10 while creating a file system & specifying the size. Please advice

So when addressing an x86 system with a seperate /boot or other partition you’ll have great difficulty in making this happen.

I was able to get it going on x86 by moving all the data to one fdisk partition. Also using installgrub instead of installboot.

Its a good script if u find urself in a pain to type the commands in the beggining,

I prefer u do typing the commands manually,
once u get to know whatz happening with them,
U can go for the script..

Happy Mirroring !!!!

[...] Kids… DO NOT TRY THIS AT HOME! If this is not done exactly right, you will render your system unbootable and corrupt your data. That being said, under some circumstances you can take some space from your swap partition and add it to an unused one without initializing your entire disk. This is particularly useful if you decide you want to use DiskSuite to mirror your system disk, but have not allocated the 100MB partition that is needed to hold the state databases. As always, BACK EVERYTHING UP FIRST. Better yet, make two backups and store them on two different systems. This is a risky procedure, and you don’t want to lose any data! [...]

The metaroot command actually does edit your /etc/vfstab file such that it will boot off the new mirror. Once your have booted off this mirror, you metattach the other mirrors, and edit your /etc/vfstab file by hand to mount these new mirrors before rebooting again.

I guess you could do it all at once, but I like to make sure I’m coming up off the mirror before committing to mounting all the other filesystems as mirrors.

I was always under the impression that /etc/vfstab had to be edited before the reboot and mirror part of the operation.

Does it really matter?

don’t forget to edit vfstab and change the entries for your new mirrored partitions to use the mirrored disk reference. metaroot only takes care of the vfstab entry for the root partition
