extending /stand

[Mario E Mira]

What are the requirements for a succesful lvextend on /stand?
I know I have to go single user mode but Iam having a strange problem with it. Anytime I tried to extended it it comes back and tells me a known fact that it is
contiguos and there is not enough fre PE's but I have space
available on vg00.

thanks.

Mario,

The contiguous part is what's getting you. Because /stand needs to be contiguous and there are no free extents immediatley following the existing /stand, you're unable to extend it. The answer in this case, is to make an Ignite backup tape, boot off it, and reinstall your vg00, re-sizing your root lvols during the process. Ignite can be obtained here:http://www.software.hp.com/products/IUX/index.html

Hi,


There is a very good document on the hp side,

Root, /stand and primary swap have to be contiguous, hence extending /stand is impossible if you're treating it like any other logical volume. Using ignite's make_tape_recovery is the ideal way. There is a procedure which I've tested (thanks to Wodisch) and seems to work pretty well. See this thread ..

However don;t do it if you're not sure.

I you are really the adventure admin, you could boot off the Core CD,

mount /stand
create another HFS filesystem.

back up /stand

lvremove /stand

lvcreate -C y /dev/vg00/stand

lvextend it

newfs -F hfs /dev/vg00/rstand

I myself however do it with Ignite as noted above.

Zero points please.

If you're primary swap partition is lvol2 (which is typical in a "Instant Ignited" box), you could create a new primary swap partition. After that you remove lvol2 and extend lvol1 into the freed space. Viola, /stand is extended.

heck...even if lvol2 isn't your primary swap, you could still move whatever's there to a new partition and then extend lvol1

Another option is to create an additional "copy" of vg00. We call it vgaroot. Create all vg00 file systems on vgaroot with new sizes. Copy vg00 to vgaroot. Edit /etc/fstab as needed. Boot to vgaroot. Rebuild vg00 to the sizes you want. Copy vgaroot to vg00. Edit /etc/fstab as needed. Boot back to vg00. Of course, have a make_recovery in your back pocket just in case. We recopy and test vgaroot before all patch activity.
Good luck!
