Hi,
when trying to create a mfs file system I can never get is larger than 1
GB even though I actually got >6 GB of free RAM.
Depening on how close I get to the 1 GB barrier I see the following
error messages. The last attempt was successfull, but that doesn't mean
that,l even though it was successfull now, it will be again... the limit
seems to be varying.
# mount_mfs -s 2097000 swap /mnt && umount /mnt
mount_mfs: mmap: Cannot allocate memory
# mount_mfs -s 2096900 swap /mnt && umount /mnt
mount_mfs: calloc failed
# mount_mfs -s 2096833 swap /mnt && umount /mnt
mount_mfs: cannot allocate I/O buffer
# mount_mfs -s 2096832 swap /mnt && umount /mnt
... wait some time ...
# mount_mfs -s 3096832 swap /mnt && umount /mnt
mount_mfs: mmap: Cannot allocate memory
The manpage of mfs says the following:
Note however that for mount_mfs the practical limit is based on datasize
in login.conf(5), and ultimately depends on the per-arch MAXDSIZ limit.
Well, the datasize is set ti infinity for root (daemon) so it must be
MAXDSIZ that is set in /usr/src/sys/arch/sparc64/include/vmparam.h and
describes as values in byte.
for 64 bit
#define MAXDSIZ (512L*1024*1024*1024) /* max data size */
for 32 bit
#define MAXDSIZ (1*1024*1024*1024) /* max data size */
What does that 512L for 64 bit mean? However, if I read that correctly,
I should be able to allocate way more than just ~1 GB of memory for each
MFS partition?
Is anyone here able to enlighten me? Is ~1 GB the limit or do I miss
something?
Thanks in advance,
Michael
