[Resolved]Problem with Rpi, fstab and config.xml

  • Hi, I have this error with a M3 Usb3 external drive on a RPi 3


    Code
    500 - Internal Server Error
    Failed to execute XPath query '//system/fstab'.

    Any idea ? Disk is there on the webgui though

    Code
    blkid
    /dev/mmcblk0p1: LABEL_FATBOOT="boot" LABEL="boot" UUID="AE82-4BC1" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="c9105ecc-01"
    /dev/mmcblk0p2: LABEL="rootfs" UUID="6d2ff93e-eacd-415c-96d5-4611ad21e05f" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="c9105ecc-02"
    /dev/sda1: LABEL="HARDPI" UUID="0da70cce-f234-4acc-96c9-fe45b486763b" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="365df5b8-01"

    Thanks :)


    The one I wrote in the previous message. It's when I try to add a file system in the webGUI. Nothing special in syslog

  • M3 Usb3 external drive on a RPi 3

    Link to it. And the size of the drive.

    And the full specs of the Pi.


    And what is uname -a output?

    Can't use the code box when there is to much caracters

    You can put the output in a file and attach it to a post though. Much better than using third party site.

    You didn't post the full error (copy from the Bell in the top right of the web interface).


    Output from the following would be helpful:

    sudo mount /dev/sda1 /mnt

    sudo umount /dev/sda1

  • Oh I did't knew there is more in the bell :/ Sorry


    sudo mount /dev/sda1 /mnt --> ok (but no file system to mount on webgui)

    sudo umount /dev/sda1 --> ok (file system in webgui but same error)


    Thanks again

    I did't knew there is more in the bell

    And it isn't helpful unfortunately.


    sudo mount /dev/sda1 /mnt --> ok (but no file system to mount on webgui)

    sudo umount /dev/sda1 --> ok (file system in webgui but same error)

    These were to only see if there was any error mounting the filesystem. They would not help anything in the web interface.


    I would try mounting in the web interface again. Maybe reboot and try again. Post the output of sudo dmesg | tail -n40 if the error message in the web interface is the same.

    RPi2 only has USB2 ports.

    You can't use portable drives with it.


    You need a proper USB drive with external power.


    And speed won't match the speed of the drive.

  • Thanks, the total amount of current delivered by those USHB ports should be ok.


    I have the same error when I plug a usb flash drive


    Any hint to rester config.xml ? or have a clean fresh install ?


    thanks

    Sorry but I don't understand what you mean with this.


    Any hint to rester config.xml ? or have a clean fresh install ?

    You have less troubles by fresh install.


    But don't expect great performance with it.

  • Sure I hear.


    The thing is I did try with a classic thumb drive and I have the same error. Everything worked fine till last week, by the way, with an exfat drive till I realized that file permissions were a mess with docker. I did changed to ext4, then messed up with fstab, then I don't know.... Now here I am with those errors.


    I said that USB has always a voltage of 5V. I have a good power supply attach to my Rpi2 though(I know I don't have to expect much performance). Since this disk is in USB3 mode, I think it drained to much current, and then the voltage drops (maybe I'm wrong but I have some electronic notions).
