Once again I have been tweaking ubd_kern to support lots of disks since I
need it for recovery
but I hit (even on a plain 2.6.15-bs1 kernel)
allocation failed: out of vmalloc space - use "vmalloc=<size>" to increse
size
Failed to vmalloc COW bitmap
ubd0: Can't open "COW0": errno -12
but I already had vmalloc=128M (which should be the default) and
vmalloc=256M and mem=384M on the command line.
I can't seem to locate where the equivlaent of arch/i386/kernel/setup.c has
the vmalloc= option on arch/um though
has anyone hit something like this before each of the bitmaps should only
take about 60M of memory and at this point I have only tried to allocate 1
for a single 250G ubd device
This will present a larger problem when I get everything working and try to
allocate all 10 drives worth of bitmap ~600M
I suppose I may have to go back to the paged bitmap logic but it is still a
mess...
The multiple major numbers and C:H:S from mconsole do seem to work correctly
though
