*Shrug*. Troll or not, the fact is that some of us have to work with
Linux systems and get them backed up. And to be honest XFS support
is a big factor in choosing Linux over other free OSes like *BSD because now
we don't have to format ~TB worth of IRIX disk when moving them to a new
platform. Linux may have not be close to IRIX in terms of stability or
scalability but the siren song of commodity PC hardware vitiates all logic.
I am not certain whether Torvalds was referring to ext2 dump or block
level backup in general. The decision to use the page cache rather than
buffer cache may be different from what BSD or SysV have done, but I don't
think it is totally without merit. In exchange for greater difficulties in
writing utilities like dump, there is the supposed advantage of simplifying
the filesystem programming API and so on. Also SGI's port (albeit with
numerous patches) of XFS and presumably the IBM JFS port demonstrate that
you can have a dump-like util for journaled filesystems under Linux.
As for my XFS progress on Linux:
I downloaded the SGI patched 2.4.3 kernel and utils and installed it on
a box running a Mandrake 8.0 installation. I also had to grab the
updated quota-utils from SourceForge. I made an XFS filesystem, copied
over some stuff, started some r/w to files, did the power on/off and it seemed
to recover properly.
I applied quotas and went over quota and the behavior was as expected.
I made some backups with Amanda using GNU tar and xfsdump and the recovery
under both was consistent. I followed suggestions to remove ext2 dump so
Amanda would detect xfsdump and recompiled, but I find this rather inelegant.
I plan to make a JFS partition as well, so this machine will
have multiple dumps, and I'd like to be able to specify which dump to
use for a filesystem in my amanda.conf file.
