System: NetBSD krishna.mogua.com 1.6ZK NetBSD 1.6ZK (GENERIC) #0: Sun Feb 22 16:36:12 KST 2004 junyoung@krishna.mogua.com:/u0/junyoung/src/sys/arch/i386/compile/GENERIC i386

>Description:
The GENERIC kernel displays a warning when it tries to mount a lfs volume
(usually on system startup):

lfs_mountfs: please consider increasing BUFPAGES to at least 0

It is coming from lfs/lfs_fsops.c, line 1275 as of -r1.143:

	if (fs->lfs_ivnode->v_size > LFS_MAX_BYTES) {
		fs->lfs_flags |= LFS_WARNED;
		printf("lfs_mountfs: please consider increasing BUFPAGES to at least %lld\n",
			(long long)(fs->lfs_ivnode->v_size * bufpages / LFS_MAX_BYTES));
	}

Here bufpages is 0, so that leads to a bogus message "... at least 0".

Disklabel configuration on my system is as follows:

#        size    offset     fstype [fsize bsize cpg/sgs]
 a:  26371296        63     4.2BSD   1024  8192 46600  # (Cyl.      0*-  26162*) <- ffS

>How-To-Repeat:
Boot with GENERIC kernels from 2/4 through today. Prior kernels may have
the same symptom, but I haven't tested yet.
