:Try editting line #1226 of sys/nfsclient/nfs_vfsops.c, where
:it sets nm_maxfilesize = (u_int64_t)0x80000000 * DEV_BSIZE - 1; and make it
:something larger.
:
:I have no idea why the limit is set that way? (I'm guessing it was the
:limit for UFS.) Hopefully not some weird buffer cache restriction or
:similar, but you'll find out when you try increasing it.:-)
This is a throwback to when the buffer cache used 32 bit block numbers,
hence 0x7FFFFFFF was the maximum 'safe' block number multiplied by
the lowest supported block size (DEV_BSIZE), that could be handled by
the buffer cache.
That limit is completely irrelevant now and should probably be set to
0x7FFFFFFFFFFFFFFFLLU (since seek offsets are signed).
