fmthard showing error with prtvtoc

kumarmani · January 17, 2009, 8:44am

Hi all,

I am trying to use the disk for mirror where in the mirror disk is of 160 gb and the rootdisk is of 80 gb. when i am trying to write the vtoc i am getting below error

i tried the below command

#prtvtoc /dev/rdsk/c0t0d0s0 |fmthard -s -/dev/rdsk/c0t2d0s0

and got below

fmthard : Partition 2 specifies the full disk and its not equal
full size of disk. the full disk capacity is 267374640 sectors

what can be done apart from manually slicing the second disk

Thanks

Post the output of prtvtoc for both disks. Also do you want to simply ignore the send half of the second disk...that it pretend that it is 80 GB?

you can try this? :o
#prtvtoc /dev/rdsk/c0t0d0s0 |fmthard -s - /dev/rdsk/c0t2d0s0

kumarmani · January 17, 2009, 1:21pm

That's i what i tried, however no luck

incredible · January 17, 2009, 1:29pm

Did you label your 2nd disk first?

kumarmani · January 17, 2009, 1:30pm

No i did't, as there is nothing

seg · January 17, 2009, 1:37pm

he was pointing out a typo

Original:
-/dev/rdsk/c0t2d0s0

Fixed:

/dev/rdsk/c0t2d0s0

incredible · January 17, 2009, 1:39pm

label your disk 1st using the format utility and then try again

incredible · January 17, 2009, 1:40pm

seg, you're slow just now he didn't even had the "-", then he edited that

kumarmani · January 17, 2009, 1:41pm

Thanks incredible! That's true it was not in the post

I just labeled it and then tried however same error

seg · January 17, 2009, 1:42pm

haha, doh! just started the daily forum browsing.

OP: look i think you're going about this whole thing the wrong way. If both drivers were the same size and vendor then a copy of the partition table (using slize 2!) would be fine, but given the situation as I understand it you should just run format and manually set the partition table to match as needed. It's not terribly complicated.

incredible · January 17, 2009, 1:45pm

prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t2d0s2

should work!

kumarmani · January 17, 2009, 1:45pm

Thanks seg, that there in mind, however just thought if i can get some help from experts here

seg · January 17, 2009, 1:48pm

I'm not sure I understand the tone or goal of that post. Do you think I am incorrect in recommending a manual partition layout?

incredible · January 17, 2009, 1:48pm

Im sleepy here man, no wonder cannot "see and think"

kumarmani · January 17, 2009, 1:49pm

I am sorry Incredible , its not working working .

I just got to the see the below waring in dmesg " Corrupt label; wrong magic number " for the new disk.

is this one is the culprit ?????

incredible · January 17, 2009, 1:50pm

Sure , we can also do a manula partition layout if command-line is freaking us out.. hehehe

seg · January 17, 2009, 1:50pm

That drive needs a label. Use format.

kumarmani · January 17, 2009, 1:51pm

No seg, i am saying that's there in mind i was thinking if fmarhard work then well and good if not of course we have manual option
