Transfer file system

enrico.nic — Thu, 07 Jul 2005 05:16:54 GMT

Hi

I have copied a file system from /opt to /opt2 (/opt2 resides on a new disk, and a new volume group). Now I wonder to mount on /opt the new disk, and on /opt2 the old partition.
Should I do this directly on /etc/fstab, or should I make something on volume groups ?

Thank you for your help

Enrico

Hi,

Are we talking about TRU64 with LSM or HP-UX with LVM?

greetings,

Michael

HP-UX with LVM, here is an output of the 2 filesystems:
# bdf
Filesystem kbytes used avail %used Mounted on
/dev/vg02/lvol1 4190208 4109306 75903 98% /opt2
/dev/vg00/lvol11 2854912 2056970 748832 73% /opt

Sorry for the un-specification

I thought so.
This is the TRU64 forum.

simply make the following changes
from
Filesystem kbytes used avail %used Mounted on
/dev/vg02/lvol1 4190208 4109306 75903 98% /opt2
/dev/vg00/lvol11 2854912 2056970 748832 73% /opt

to
Filesystem kbytes used avail %used Mounted on
/dev/vg02/lvol1 4190208 4109306 75903 98% /opt
/dev/vg00/lvol11 2854912 2056970 748832 73% /opt2

Hi,
Change he fstab and reboot the system (normally you can't unmount /opt if the system is up).

Enrico,

Simply unmount them (if you can unmount /opt without having to go to single user mode, that is) and remount them the way you want. Or, since you're probably going to have to reboot anyway, edit /etc/fstab, switch the two mount points and reboot.

Hi

Sorry for having posted in the wrong place: the strange thing is that the already selected link in my browser is that of HP-UX system administration, not the Tru64 system administration.

Changing the mount points in /etc/fstab solved the problem.

Many thanks

Enrico
