copy a filesystem from HP-UX to Linux Suse

support_billa — Tue, 14 Feb 2012 17:56:43 GMT

hello,

Now i have to expand the copy commands for copy a filesystem from HP-UX (vxfs) to Linux SuSe (ext3) or backwards

We had discuss here a long thread copy a filesystem best solution (local host or remote host) and now i will extend it for copying to Linux.

i hope those options are right for Linux and compatible (like cpio)

here my options:

cd /source_fs

CPIO
find .  ! \( -name lost+found -type d -prune \) -depth -print | cpio -oc |ssh root@other_host "cd /dest_fs; cpio -idumvV -H hpodc"

TAR
tar -cpvf - . | ssh root@other_host "( cd /dest_fs; tar -xBpvf - )"

PAX
pax -w . | ssh root@other_host "( cd /dest_fs; pax -v -r -pe )"

RSYNC
rsync --progress -avhz --rsh="ssh" . root@other_host:/dest_fs

DUMP
dump ???

combination of tar and zip are also solutions.

regards

some news:

when i tested files > 2 GB i detected limits... i forget :

so only options are - RSYNC and - CP (RCP/SCP) ...

i will test:

GNU version of tar, a tape file archiver

GNU version of cpio, program to manage archives of files

does anybody have experiences with this versions ?

how i detect what version of CPIO and TAR is installed ? cpio --version isn't available !

regards

here a little overview about limits of the commands:

HP-UX :      tar: Size of Files >= 8GB. Not dumped. tar is not working with a file more than 8GB
        GNU: tar: No Limit ( local copy)

HP-UX :      cpio: Size of Files >= 2GB. Not dumped.
       GNU: cpio: No Limit ( local copy)   Limit is obsolete: GNU cpio 2.6 does not write files larger than 2 GB (>2GB)

HP-UX :      pax: No Limit

HP-UX :      rsync: No Limit

Remote Copy Limit / Error:

I have problems using GNU cpio to copy to a remote host (HP-UX 2 HP-UX) files bigger >= 8GB.

command:

find /source_fs -xdev -depth ! \( -name lost+found -type d -prune \) -print | \
/usr/local/bin/cpio -ocav | \
ssh -p 22 server -l root "cd /dest_fs; /usr/local/bin/cpio-idumv"

Error: /usr/local/bin/cpio: 10 G File. field width not sufficient for storing file size

>HP-UX: pax: No Limit

You probably have to install PAX-Enh and a patch.
