'kgb' will compress those 1G archives without complaint, maybe the
problem is the size. Apparently 1G works, but 2.3G doesn't; I
haven't tested to find out the limit.
At first look it seems like it is related to LFS, a local test confirms:
open(/tmp/old_install.img, O_RDONLY) = -1 EOVERFLOW (Value too large
for defined data type)
fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 3), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7fd9000
write(1, File not found, skipping: /tmp/..., 48File not found,
skipping: /tmp/old_install.img
) = 48
write(1, Nothing to compress, archive won..., 47Nothing to compress,
archive won't be created.
) = 47
But the output message is not quite the same. Could you please provide
me with a strace?
Recompiling kgb with the necessary LFS flags (which somehow I missed
to pass to gcc but were set in debian/rules) does fix that problem.
But now I found another one:
open(/tmp/old_install.img, O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=3320379455, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7f49000
fstat64(3, {st_mode=S_IFREG|0644, st_size=3320379455, ...}) = 0
_llseek(3, 3320377344, [3320377344], SEEK_SET) = 0
read(3, \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0...,
2111) = 2111
close(3)= 0
munmap(0xb7f49000, 4096)= 0
fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 3), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7f49000
write(1, Nothing to compress, archive won..., 47Nothing to compress,

) = 47
As you can see I'm trying to compress a 3320379455bytes file (~3.3GB)
(If it matters, the disk had 2.65G free, and 'rzip' was able to
compress the same 'hda1.tar'.)
It isn't related to the free disk space, because it first performs a
check to make sure it really has to compress something.
