Hi all,
I have a weird problem with Backfire 10.03. I have tailored my fstab and I am able to mount my pendrive using mount -a manually. However, if I want it to be automatic and I put the mount -a into a script, it fails.

My fstab:

/dev/sda1 /mnt/disc0_1 ntfs-3g umask=000,dmask=000,fmask=000,uid=65534,gid=65534 0 0

Dmesg:

Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices

The error:

mount: mounting /dev/sda1 on /mnt/disc0_1 failed: No such device

Also /etc/init.d/fstab fails to mount it, but immediate manual mount -a mounts the device successfully.

Any hints what can be wrong?

Thank you.

Are you using /etc/config/fstab?

Hi Dogge,

yes, I do:

root@OpenWrt:~# uci show fstab
fstab.automount=global
fstab.automount.from_fstab=1
fstab.automount.anon_mount=1
fstab.autoswap=global
fstab.autoswap.from_fstab=1
fstab.autoswap.anon_swap=0
fstab.@mount[0]=mount
fstab.@mount[0].enabled_fsck=0
fstab.@mount[0].enabled=1
fstab.@mount[0].target=/mnt/disc0_1
fstab.@mount[0].fstype=ntfs-3g
fstab.@mount[0].options=umask=000,dmask=000,fmask=000,uid=65534,gid=65534
fstab.@mount[0].device=/dev/sda1
fstab.@swap[0]=swap
fstab.@swap[0].device=/dev/sda2
fstab.@swap[0].enabled=0

Check whether "block-hotplug" is installed. USB needs delayed mounting.

block-hotplug is installed...

 opkg list-installed | grep hotplug
block-hotplug - 0.1.0-1
hotplug2 - 1.0-beta-1

As I said before, I am able to mount -a manually, but running /etc/init.d/fstab or adding mount -a command to any script fails. I cannot explain why it happens so.

... in my case (backfire) this was helpful:

@meta96: Thank you, but that does not work either.
/etc/init.d/fstab

start() {
    config_load fstab
    mkdir -p /var/lock
    lock /var/lock/fstab.lck
    # echo '# WARNING: this is an auto generated file, please use uci to set defined filesystems' > /etc/fstab
    lock -u /var/lock/fstab.lck
    config_foreach do_mount mount
    config_foreach do_swapon swap
    mount -a
}

(see, I tried to add "mount -a" to the script)
Result:

root@OpenWrt:~# /etc/init.d/fstab restart

The discussion might have continued from here.
