from old disk to new disk using cpio command. what options will facilitates copying entire directory tree from old PV to new VG.
Iam not acquainted with cpio, but i think this is what i need in other to move datas from the old PV to the new volume groups.

Bassey,
I would think you would want to use -odmv, and the syntax would be:
find . -depth -print | cpio -odmv > newdisk

the o means output, d means create directories as needed, m means retain mod time, and v is verbose.

Bassey,
I would think you would want to use -pdmv, and the syntax would be:
find . -depth -print | cpio -pdmv newdisk

the p means passthrough, d means create directories as needed, m means retain mod time, and v is verbose.

Hi Bassey,

cd
find . -xdev -print | cpio -pdvum

If you want a whole filesystem to be copied, is its mount point, is the mount point of the new filesystem.

The -xdev flag will prevent find from crossing filesystem boundaries so that you could find files under / but not files under /usr, /tmp, /var, etc...

Best regards,

Dan

Hi,

Copy over the entire original stand directory to the /stand.tmp(new mount point)
directory.
# cd /stand
# find . -xdev -depth -print | cpio -pxdumv /stand.tmp

Good Luck
