I'm attempting to create a mirror of my rpool with the aim of moving
the os to the new disk making it bootable then pulling the original
rpool disk out. And in a few days dropping in a new matching disk for
mirror of rpool once again.
The current rpool resides on a 25 gb partition on a 60 gb disk. I want
to more the OS (rpool), lock stock and barrel to a new 500 gb disk with
one 500 gb partition (slice). So the old and the new are vastly
different sizes.
In some of the directions I've seen for doing such a thing, one of the
steps is to transfer the vtoc One example:
prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
Well, I'm new at this and decided to take a look at that output before
piping it.
Since the disks have very different number of cylinders, I just want to
make sure this is the right thing to be transferring:
So can anyone tell me if this looks kosher?
# prtvtoc /dev/rdsk/c3d1s2
* /dev/rdsk/c3d1s2 partition map
*
* Dimensions:
* 512 bytes/sector
* 63 sectors/track
* 255 tracks/cylinder
* 16065 sectors/cylinder
* 3275 cylinders
* 3273 accessible cylinders
*
* Flags:
* 1: unmountable
* 10: read-only
*
* Unallocated space:
* First Sector Last
* Sector Count Sector
* 0 16065 16064
*
* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 2 00 16065 52548615 52564679
2 5 01 0 52580745 52580744
8 1 01 0 16065 16064
So will it be a mistake to write the above output thru fmthard onto a
vastly larger partition.
