help with step 4

[smartelf]

Hello, I am having a problem with step 4.
when I do this:

Code: Select all

mount -o loop -t ext3 /dev/mapper/store-android--system /tmp/system/

I get:

Code: Select all

mounting /dev/mapper/store-android--system on /tmp/system/ failed: Invalid argument

Thanks

Run the following command in novaterm and verify you correctly built store-android--system:

Code: Select all

lvs

Here it is:

Code: Select all

That looks good, verify that you have created /tmp/system and that it isnt already mounted by running:

Code: Select all

mount | grep system


[smartelf]

I get nothing

Code: Select all

c:\Program Files (x86)\Palm\SDK\bin>novacom -t open tty://

Hmm dont know about running those commands via novacom, have you tried using novaterm and typing them manually? They should work as you are root...

[smartelf]

I tried novacom, novaterm and putty, all with the same results

[fnj00]

I tried novacom, novaterm and putty, all with the same results

which build of WebOS are you running currently?

[smartelf]

just tried again with novaterm after rebooting the touchpad. /tmp/system dir was gone, but after I remade it, still getting the same error.

I have webos 3.0.2
also, do we need the -o loop parameter, i tried it without it and still no luck, but according to the device, loop is ignored:

Code: Select all

BusyBox v1.17.3 () multi-call binary.

Usage: mount [OPTIONS] [-o OPTS] DEVICE NODE

Mount a filesystem. Filesystem autodetection requires /proc.

Options:
        -a              Mount all filesystems in fstab
        -r              Read-only mount
        -w              Read-write mount (default)
        -t FSTYPE       Filesystem type
        -O OPT          Mount only filesystems with option OPT (-a only)
-o OPT:
        loop            Ignored (loop devices are autodetected)
        [a]sync         Writes are [a]synchronous
        [no]atime       Disable/enable updates to inode access times
        [no]diratime    Disable/enable atime updates to directories
        [no]relatime    Disable/enable atime updates relative to modification time
        [no]dev         (Dis)allow use of special device files
        [no]exec        (Dis)allow use of executable files
        [no]suid        (Dis)allow set-user-id-root programs
        [r]shared       Convert [recursively] to a shared subtree
        [r]slave        Convert [recursively] to a slave subtree
        [r]private      Convert [recursively] to a private subtree
        [un]bindable    Make mount point [un]able to be bind mounted
        bind            Bind a file or directory to another location
        move            Relocate an existing mount point
        remount         Remount a mounted filesystem, changing flags
        ro/rw           Same as -r/-w

There are filesystem-specific -o flags.


[smartelf]

was finally able to fix the issue. it appears that the partition wasn't formated correctly.
