To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Hi All,

I will put it in more simple way ....
I have 7 hard disk in which c1t0d0s0 is for root and that is mirrored to c1t2d0s0 and rest are like ...
c0t5d0 - 18GB
c0t6d0 - 76GB
c0t4d0 - 18GB
c1t3d0 - 18GB
c0t7d0 - 36GB

I need to configure mirroring for two more mountpoint using c0t6d0 disk with 25GB space.But i am short of another 76GB disk.Is there any other method to achieve the same?

Thanks in advance
Renjesh Raju
