filesystem copy from one host to other

[vaman]

How you move a file system from one host to another. ( Assume that
both are using SAM )

[Darin S. Lory]

Do you mean copy, or move underlying disks so taht the target system can read them again?

I like using vxdump/dump

/usr/sbin/vxdump 0f - /dev/vgXX/lvolXX | remsh myhost '(cd /apps/mydir; /usr/sbin/vxrestore -rf -)'


Ensure that the systems are trusting one another. The remsh trust can be temporary - remove after complete

Hi there.
What about the good old fbackup / frestore ?

Vaman,
Fbackup can do the job for you but then you have to back it up on tape first and then restore the tape back on the other system.

Other way i would see is:

1. Export the filesystem, mount it on the other system and then copy it to new filesystem on that system.

2. Configure rsh/rcp ( you need to set up either .rhosts or hosts.equiv files on both the servers) and simply do the remote copy using rcp. Well if it is huge filesystem then better to backup it up on tape and then proceed with restore on the other system.

Remember both this option will put considerable load on your network.

Hope that helps.

By simple and effective, go to Network File System ( NFS )

machine1 ----> machine2

Export the file system with access to machine2

On machine2 mount the file system and use it. If you want to make use remote host (machine1 file system) as an additional resource then no need to copy into the localhost (machine2)

Else after making nfs setup, copy the needed file sytem and umount it there.


Else go for r* commands. Specfically, rcp there. Make setup rhosts file to make remote command execution between two hosts.

I Suggest you to go for NFS*
