inrease partition size
hi,
i created a partition c1t0d0s5 sized 10gb and a soft partition on it. now i want to expand this size to 15gb (my hard disk is 36gb). anybody show me the way to do that, please.
here are the outputs of the df and format commands:
Code:

Did you create a soft partition, or just a metadevice ?

Whats the output from metastat -p

yes, i did.
Code:
# metastat -p
d1 1 1 c1t0d0s1
d0 1 1 c1t0d0s0
d25 2 1 c1t0d0s3 \
         1 c1t0d0s4
d26 -p c1t0d0s5 -o 1 -b 8388608

thanks

Why would you create a soft partition that is the whole disk slice ????

You use soft partitions if you have a big lun or disk that you want to slice up into more then 6 partitions/slices/filesystems ... what ever you want to call it today.

For a 36GB disk I would have used standard disk slices and I would have created only 2. A root and a swap partition

But since you want tu use a soft partition for slice5, what you should have done was use the rest of your available disk in slice5 ..

You should of had slice 5 using the cylinders 4897 - 24619

In your case though your only option is to create a slice 6 from cylinders 12157 to 24169 and then thats it, you can modify your disk any more...

Also why have only one disk ? You should really use a min of 2 disks and mirror them. You leave yourself open to disaster with only one disk.

If I was you I would buy a second disk, partition it up to the sizes you need(partition / to use the same cylinders as your first disk so you can attach it as a mirror), copy your data from the first disk to the new disk, mirror your root filesystem(d0), then change the rest of your first disk to look like the new partitions on your second disk and attache that half to your mirror. Then you will have the disk layed out the way you want it and it would be mirrored.

It would look something like this:
Code:
d10 -m d0 d20 1
d0 1 1 c1t0d0s0
d20 1 1 c1t1d0s0

d1 -m d11 d21 1
d11 1 1 c1t0d0s1
d21 1 1 c1t1d0s1

d3 -m d13 d23 1
d13 1 1 c1t0d0s3
d23 1 1 c1t1d0s3

d4 -m d14 d24 1
d14 1 1 c1t0d0s4
d24 1 1 c1t1d0s4

This means that you filesystem would look like this
Code:
Filesystem             size   used  avail capacity  Mounted on
/dev/md/dsk/d10        9.6G   3.4G   6.1G    36%    /
/proc                    0K     0K     0K     0%    /proc
mnttab                   0K     0K     0K     0%    /etc/mnttab
fd                       0K     0K     0K     0%    /dev/fd
swap                   2.3G    40K   2.3G     1%    /var/run
swap                   2.3G     0K   2.3G     0%    /tmp
/dev/md/dsk/d3         5.2G   224M   4.5G     5%    /globalfs
/dev/md/dsk/d4        10.0G   9.1G   900M    92%    /u01

I'm assuming that d1 is swap and that slice7 is for your metadb. The size of d3 and d4 would be adjusted on your second disk before changing sizes on your first disk and attaching to your mirror.

The normal practice with SVM is to use d? for the mirror and d1? for the first disk and d2? for the second disk, But since you used d0 for the root partition you root mirror is d10. It should realy look like this:
Code:
d0 -m d10 d20 1
d10 1 1 c1t0d0s0
d20 1 1 c1t1d0s0

Just as an FYI.. here is an example of the use of softpartitions..
d80, d90, d100, d110 and d120 are logical drives from some attached disk arrays, each logical drive is 955GB
Code:
d0 -m d10 d20 1
d10 1 1 c1t0d0s0
d20 1 1 c1t1d0s0

d1 -m d11 d21 1
d11 1 1 c1t0d0s1
d21 1 1 c1t1d0s1

d3 -m d13 d23 1
d13 1 1 c1t0d0s3
d23 1 1 c1t1d0s3

d4 -m d14 d24 1
d14 1 1 c1t0d0s4
d24 1 1 c1t1d0s4

d5 -m d15 d25 1
d15 1 1 c1t0d0s5
d25 1 1 c1t1d0s5

oops sorry,
I posted my format output but I didn't post the partition layout of the logical drive, so you can see that we use the whole disk.

Here it is. This is disk 3 in the format output which is d80 - d87, slice 7 is used for the metadb

Total disk cylinders available: 65533 + 2 (reserved cylinders)
