I suppose that the sparc machine can read its own dumps at least, no? :)

Good. I should add a pointer on the web page to this... By the way, 
on your page it should be 'rmt' instead of 'rpm' :)

Yes, it works on alpha. It seems that the sparc doesn't write correctly
the dump.

Looks to me like some kind of byte swapping bug. This should be fixed,
but unfortunatelly I don't have access to a sparc...

If you have some time, you can try to debug this. I'll start by making
two (small) file dumps, a x86 one and a Sparc one (of an empty directory,
for example), then try to figure out the differences and track down up
to the incriminated portion of code.

Send me the two dump, and I'll also try myself to see what's happening.

Thanks.

Stelian.

[Dump-devel] sparc rpms

[Rob C. <ce...@ah...>]

Hiya,

The rpms are built.  The sparc dumps them fine (via tape on i386), but the
i386 can't read them.  The sparc restore reads the tape dump fine.

Website link to sparc rpms:
http://njlug.rutgers.edu/projects/dump/index.html

Just some notes:  It looks like the x86 machine tries to do the right
thing, but doesn't :) Something to add to the TODO list?  I should be able
to restore to both platforms (including alpha?) seamlessly -- at least
text documents.  I don't expect sparc executables to run on the x86 :)

On the i386, this is what restore shows:

[root@snow /root]# restore ivf /dev/nst0
Verify tape and initialize maps
Tape block size is 32
Note: Doing Byte swapping
Dump   date: Tue Feb  1 20:35:07 2000
Dumped from: the epoch
Level 0 dump of / on anole.sjrcd.org:/dev/sda1
Label: none
Note: Doing Quad swapping
Extract directories from tape
. is not on the tape
Root directory is not on tape
abort? [yn] n 
Initialize symbol table.

I have not made this automatic :)

The source includes a dump.spec file (which needs to go into the SPECS 
directory). This, along with dump tarball (to be placed into the SOURCES
directory) is all you need in order to construct a source rpm, using, for
example:
	rpm -ba SPECS/dump.spec

[Dump-devel] sparc rpm

[Rob C. <ce...@ah...>]

Hi.  Its me.  I'm the one with the thesis to write.  Just handed in a
partial draft and taking a little break.   I'd like to offer up a .rpm
build on a SparcLinux box.  If I grab the source, is there a particular
command other than make, to build the rpm for the release?  say maybe?

make rpm

Needless to say, I've never created a rpm before, so any pointers would
help too...

I also saw and agree that the size estimate should have been bytes, but
being unfamiliar with the code didn't want to change too much :)

At any rate, I have used a prior version of dump/restore on a SparcLinux
box to a remote i386 box with the tape drive and all was well :)  Being
the sparcLinux box was using an ext2 filesystem as well, it should have
worked.  If there are any bugs in the Sparc port, I guess I'll be glad to
take a crack at the 32 bit side.   I don't have a 64 bit machine to look
at -- I didn't win an alpha leftover from TheLinuxStore either :(

Good choice to move to dump.sourceforge.com.
