[RESOLVED] How to mount USB flash with russian filenames



  • Hi, guys!
    I need to use USB flash contain russian filenames (written in Windows). Default mounts:

    # cat /proc/mounts | grep sda1
    /dev/sda1 /mnt/sda1 exfat rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=utf8,namecase=0,errors=remount-ro 0 0
    

    ls command gives errors:

    root@Omega-3079:~# ls -l /mnt/sda1

    Filename, which produces error is '/mnt/sda1/женщина.bmp'. If I read USB flash directory in python, this file also "absent". OSError, IOError does not happens.

    Centos7 mounts the same flash with parameters:

    /dev/sdb1 /run/media/pavel/FLASH8 vfat rw,nosuid,nodev,relatime,uid=1000,gid=1000,
                                           fmask=0022,dmask=0022,codepage=437,iocharset=ascii,
                                           shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0
    

    I tried this:

    ~# mount -o codepage=cp437,nls=ascii /dev/sda1 /mnt/sda1
    [ 3295.091098] ntfs: (device sda1): parse_options(): Unrecognized mount option codepage.
    [ 3295.163115] ntfs: (device sda1): parse_options(): NLS character set ascii not found.
    mount: mounting /dev/sda1 on /mnt/sda1 failed: Invalid argument
    

    But Omega's Linux does not understand this 😞 .

    How I should mount USB flash to avoid these errors?

    Firmware is latest 0.3.3 b251



  • The problem seems to be fixed

    # opkg install kmod-nls-cp1251
    # umount /mnt/sda1
    # mount -o codepage=1251,iocharset=utf-8 /dev/sda1 /mnt/sda1
