>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
b: 263088 26371359 swap # (Cyl. 26162*- 26423*)
c: 51211377 63 unused 0 0 # (Cyl. 0*- 50804)
d: 156301488 0 unused 0 0 # (Cyl. 0 - 155060)
e: 24576993 26634447 4.2BSD 1024 8192 46552 # (Cyl. 26423*- 50804) <- lfs
f: 37784880 51211440 MSDOS # (Cyl. 50805 - 88289)
g: 33398127 122897313 NTFS # (Cyl. 121921*- 155054)
>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.
