Hi all,

Is it possible to do a ufsdump of nfs mounted partitions.
I've heard someone mention it in passing but have never
looked further into it till now.

Thanks... Pete

Yes, it allows you to dump a mounted filesystem.
Backup can be more consistent ( at times it gets us into tight spot )
when the filesystem is unmounted. But with root it works :)

Tried this ever ??
suppose: /var is a mounted file system: suppose : /dev/dsk/c0t3d0s4
you can try this:
 ufsdump 0cuf /destination-device /var/somesdir

Even if you specify a file/dir ( possible obviously in a mounted
filesytem situation) it is going to identify the filesystem it belongs
to and dumps appropriately.

NFS-mounted filesystems don't have local devices (in /dev).  ufsdump
operates by opening the device and reading the filesystems's structure
directly from the partition.

So, you can't use ufsdump on any filesystem that doesn't have a local
device associated with it, which includes NFS filesystems and tmpfs
filesystems like /tmp.

Believe it or not, ufsdump cannot be used to dump non-ufs filing systems
that *do* have an associated raw device, either (hsfs or pcfs filing
systems, for example).

There *is* a reason why it is called ufsdump... :-)

Ufsdump works on inactive/unmounted filesystems, otherwise, ufsdump
will be inconsistent and recovery is impossible.  If your goal is to
have a dump of nfs mounted filesystems for future disaster recovery,
you can tar the nfs mounted partitions from the server where they are
mounted, although, i think tar won't be able to archive the snapshot
directory.  Or consider other alternatives such as using a backup
software that has a module to backup nfs files.

I really liked the vxdump and vxrestore. Which I believe also allow for
dumping UFS slices. Again, for a RootFS ufsdump or a CPIO can be an
ideal situation.
