I have not tested it yet myself, but version 1.2 of gnutar was
released yesterday (see http://www.gnu.org/software/tar/#TOCreleases )
and of particular interest is this feature (quoted from the page):
"New options --no-check-device, --check-device.
The --no-check-device option disables comparing device numbers during
preparatory stage of an incremental dump. This allows to avoid
creating full dumps if the device numbers change (e.g. when using an
LVM snapshot).
The --check-device option enables comparing device numbers. This is
the default. This option is provided to undo the effect of the
previous --no-check-device option, e.g. if it was set in TAR_OPTIONS
environment variable."
Best,
Jordan

And I, like an idiot, didn't notice we were discussing an NFS
problem,
which may be another manifestation of the same problem, but that

decides to
move an LVM2 volume from 253,0 ro 254,0.
The patch JLM posted won't fix it, but his proposed command-line
option
will.
Post please, I don't believe I've seen it. I had some email
problems over
the weekend due to my / partition being in bad need of an fsck.
2.6.24
running tickless was a friggin nightmare.
Thats why I'm asking about Schiling Tar, aka S-Tar. Does that
fix the
problem?, and can amanda use it?
Yes, but its semantics are very different from GNU Tar -- it's not a
drop-in fix.
I was afraid of that.
The ultimate weapon of course in any philosophical war, which
this is,
is to fork tar and fix it if STar isn't usable. At this point,
and while
I'm not capable of doing it, I'm not a bit allergic to the fork
idea.
Its bitten me so often that I'll alpha test anybodies efforts in
that
regard. Gleefully.
Sure, but threatening a fork is un-diplomatic, and not called for
just
yet. Let's start with a concerted public-relations effort :)
I doubt if my messages on the subject were the only ones they got,
and from
the attitude displayed in the replies I got, a fork IS the next
step. They
are immovable on the subject. They consider that a change in the
device
mapping numbers are prima-faci evidence of a stolen tar file trying
to be
recovered to a disk that they don't belong to. A huge security
problem in
their view.
Humm, didn't we have some scripts that could inspect and repair the
index files when this happened? Probably lost when I woke up one
morning
and found my well developed FC6 install wasn't re-bootable, LSN0 on
/dev/hda had one non-zero byte left in it.
Yep -- it's called tar-snapshot-edit, and it's available in recent
releases of GNU Tar. Just google for it.
I'll do that, got it.
Thanks, Dustin.
To continue this thread I have now subscribed to the bug-tar list
about 24
hours ago, but two messages I've sent have been bounced. So I tried
to
re-confirm since I still had the message, and that bounced with
the 'confirmation string invalid'.
I'm about up to my eyeballs in gnu BS, its not worth the effort to
talk to
those fence posts.
I'd write a cron script to hit them every 10 minutes, but I don't
need the
bounces. If you can get in, tell them to fix their (*&^$ mail
server to
accept messages from somebody newly subscribed.
