hmmmm .. afraid I spoke too soon. a few trial runs worked, but when I
put my build system back to normal using the new binary I compiled, I
started getting this:
libisofs: FATAL : Cannot convert name '.catalog' to ASCII
libisofs: FATAL : Memory allocation error
xorriso : FAILURE : Failed to prepare session write run
xorriso : NOTE : -return_with SORRY 32 triggered by problem severity FATAL
Which seemed very strange since it ran fine for me on the same system.
After poking around a lot I've found that the contents of the source dir
seems to affect it - the difference between the working run and the
broken ones was one file. I thought it might have something to do with
clearcase (the "one file" in question was a view private object mixed in
with some other stuff), but I can reproduce in a plain old directory,
too. It's also not specific to .catalog, which is being generated by
the -c mkisofs-style option - if I drop that option, it'll hit the same
error on some other file in the source dir. It also doesn't appear to
be dependent on where I'm sending the output. It doesn't do it on
linux, only Solaris (sparc), at least for the same source directory.

I think the subject pretty much says it - I'm trying to write out to
large disk array with ~4.5TB of free space. I'm guessing this is a

Looks much like that.
I assume you experience this on Linux. In this case the number of bytes
is read 64 bit from statvfs(2). The number is then stored as 64 bit.
Before writing it is divided by 2048 and stuffed into a signed 32 bit
integer, which then is compared against the predicted image size.
are there any switches to skip the free space check
or otherwise get me past this?
You may hide the target by writing to a pipe.
xorriso -outdev - ... | cat>target_image.iso
But this will only work for single session or with explicitely obtained
Next-Writable-Address numbers as is tradition with mkisofs+cdrecord.
I am currently exploring how to deal better with such a size.
(Will have to fake 4.5 TB of capacity as my disk is only 500 GB.)
As soon as i have a test candidate, i will upload a development tarball
of GNU xorriso and ask you to try it.
One brute-force candidate would be to curb media capacities to 2 TB -
already when they are read from the system.
If you have the source code of your xorriso at hand, you may try this

It would be interesting to know whether this shows any inconsistencies
with your disk array.
Have a nice day :)
