Increase file system with a new disk

[marrow]

Have an old test E450 not mirrored (Solaris8) 3 x 9Gb Disks.
/u01 is full of data on say disk2. Have spare empty 9Gb on disk3, need to add new space to u01. What's the best method of doing this, just a link?

what I would do is partition the spare drive to the size you wnat and theufsdump the information from the current drive to the new one. Then you can new drive to the current slot of the old drive or edit your vfstab to point to the correct drive and partition.

Check out this link;

I just did this on one of my systems the other day and it works perfectly for what you want.

thanks

Thanks cndadams, I didn't even notice the typos, will let you know,

I think what he wants to do is combine disk2 and disk3 into one large filesystem.

Disksuite I guess ? or SVM as it's called now.

Spot on dandan123, that is what I really wanted. I will check your page, thanks

dandan123 makes a good point if say your disk 2 is 9 gig and you had one partition and it is full, then you would want to use SVM/disksuite, create the volume and grow the filesystem using space on the second drive.

If it is just the fact that when you originally created the partitions on disk 2 you made it smaller then 9gig (say 5gig) and it filled up the do the process I mentioned first.

Or if you think the filesystem will grow beyond the 9gig in the future go with svm/disksuite.

I think that should cover the bases

Thanks

I do not have any access (as yet) to this system, so I'm guessing ahead but they do want to extend for example /u01 which is probably 4 or 5 Gb and add on a 9Gb chunk. OK if that's true then I'll move th 5Gb to the 9Gb and that's good. But it maybe that we want to make /u01 = 5Gb+9Gb, so that's my real question can I extend u01 onto a 2nd disk? I will get back in the morning afte reading relevant pages, thanks to you both.

If you want to add the 5G to the 9Gb, SVM is the tool to use as discussed above.

 

[marrow]

How is SVM GUI actually started? I haven't used for a while.

metatool is the gui from what I remember.

Thanks

However although it rings a bell, I can't "find / -name metatool" on any of our mirrored/solaris9 systems. The following are there though:-

system SUNWlvma Solaris Volume Management APIs
system SUNWlvmg Solaris Volume Management Application
system SUNWlvmr Solaris Volume Management (root)
system SUNWmdar Solaris Volume Manager Assistant (Root)
system SUNWmdau Solaris Volume Manager Assistant (Usr)
system SUNWmdr Solaris Volume Manager, (Root)
system SUNWmdu Solaris Volume Manager, (Usr)
system SUNWmdx Solaris Volume Manager Drivers, (64-bit)

Thanks for your help, it looks like nothing will happen for a while anyway.

marrow;

your first post showed solaris 8 which metatool is part of.

for Solaris 9 you need to use smc (sun microsystems console). If you have not used it before it will be an experience. Be careful though, the original releases of it did not work so great. When I took the original Solaris 90 class we had all kinds of problems, drives not showing up etc..

start it with command smc


Thanks

The work to be undertaken is I believe Solaris8 but I can't be certain until granted access. I will look into Solaris 9 smc (sounds useful) for my own benifit and check a Solaris8 system for metatool. Apologies for confusion CA and thanks for the advice

 

[KenCunningham]

Remember that when using metatool you will need your DISPLAY variable set appropriately, as well as a working X-windows client.

 

[marrow]

Yes no problems on that one Ken, have run up metatool on Solaris8 and smc (for the fisrt time)on Solaris9, useful tools.
