Moving /opt /usr /var into /

Derek Whigham_1 — Wed, 19 Oct 2005 03:55:40 GMT

I need to move then contents of /opt /var /usr into / then unmount them (to be removed in the future).

I am planning to move them using cp to move them to / such that /var becomes /var2 /usr becomes /usr2 and /opt becomes /opt2

Then unmount /var /usr/ and /opt

and mv /var2 back to /var

Anybody have a better way or see's any danger i n this.

Below is our setup

lvol1 vg00 LVM HFS 304 1 /stand
lvol2 vg00 LVM Swap/Dump 16368 1
lvol3 vg00 LVM VxFS 40592 1 /
lvol4 vg00 LVM VxFS 608 1 /home
lvol5 vg00 LVM VxFS 4000 1 /opt
lvol6 vg00 LVM VxFS 208 1 /tmp
lvol7 vg00 LVM VxFS 5008 1 /usr
lvol8 vg00 LVM VxFS 2000 1 /var

Hi,

Its better create one directory in / & use cpio command to move /opt /var /usr into /NEW_DIR . Using the cpio command, u can keep the permission & owner, group permission also.

Thanks.

Booting into single user mode and doing the specified operations should be correct way.

The first question that arises is why? The second is do you have enough room in / to do this? / is usually small.

Without more details, I would tend to suggest taking an ignite backup and rebuilding the system from that.

Yeap cpio is the way to go , I have completed this successfully / was 40Gb due to a field engineer mistake.

Thanks for the prompt responses
