Copying filesystem with links to other filesystems in different hosts.

[Chern Jian Leaw]

HI,

I have scenario whereby a filesystem /fs13/md6.uecommon.2/wmt8/utils/ resides on 1 fileserver, i.e fs13:

#cd /fs13/md6.uecommon.2/wmt8/utils/
# ls -l
lrwxrwxrwx ... bin->/fs12/md6.uecommon.1/utils/bin/

lrwxrwxrwx ... tools->/fs12/md6.uecommon.1/utils/tool_utils

However, the /fs12/md6.uecommon.1/ filesystems to which the contents of /fs13/md6.uecommon.2/wmt8/utils/ are pointing to resides on another fileserver, i.e fs12.

/fs12/md6.uecommon.1/ filesystems volumes are not mounted on the fileserver fs13, hence not available on fs13 fileserver.

I would like to do a rsync(differential copying), or even an rcp of the /fs13/md6.uecommon.2/wmt8/utils/ to another fileserver i.e sgfs.

Could anyone tell me how I could actually do this copying?

Note that the pointed to filesystems i.e. /fs12/md6.uecommon.2/ actually reside on a different fileserver.

Hi,

i think the most simple way of copying a directory to another server with taking care of hard- and softlinks is using tar or cpio with remsh or rexec:

on (fs13), with = sgfs

cd /path/from/;tar cf - . | rexec "cd /path/to/;tar xf -"

You may want to change some options or use cpio or pax to do it.

If you can rlogin from to without entering a password you may user remsh insteat of rexec.

You have to make sure that the third server (fs12) is mounted on with using the same mountpoints as on

Chern,

Make a symbolic link on fs13 and fs12:

fs13:

/fs12 -> /fs13

on fs12:

/fs13 -> /fs12

then they can easy rsync to each other.
