Subject: Cannot mount vfat filesystem, dmesg says "codepage cp437 not found"
To: ~alpine/users@lists.alpinelinux.org
Content-Type: text/plain; charset="UTF-8"

I have two computers.  Both are running
alpine-standard-3.12.0-x86_64.iso, from a USB stick.  Computer A can
mount a vfat filesystem on a second USB stick.  Computer B cannot.

Computer A is an Acer laptop.  Computer B (that fails to mount) is an
Asus Chromebox with the firmware flashed to Seabios.

On the Chromebox, the following lines appear in dmesg when I attempt
to mount the vfat filesystem.

[ 1793.195155] FAT-fs (sdb1): utf8 is not a recommended IO charset for
FAT filesystems, filesystem will be case sensitive!
[ 1793.197887] FAT-fs (sdb1): codepage cp437 not found

The first above line (but not the second) appears on the Acer laptop.

The mount command itself prints the following error:

localhost:~# mount /dev/sdb1 /meda/sdb1
mount: mounting /dev/sdb1 on /media/sdb1 failed: Invalid argument

lsmod shows that both the "fat" and "vfat" modules are loaded on both computers.

I found some discussion of this error message on an Arch Linux forum:
https://bbs.archlinux.org/viewtopic.php?id=171880

Does anyone have any idea why Alpine can mount the vfat filesystem on
one computer, but not on the other?

Thank you,

Parke
