External USB disk

[KiKoVasques]

Hi All

I has a Lacie nwsp2 and I need write at a external disk formatted with NTFS, but I can't make it be visible after connected it at USB port.

NAS system information:

Firmware Version fvdw-sl 17.0 patched (nwsp2)
Kernel: Linux 4.6.6 #7 PREEMPT Sun May 7 11:50:52 CEST 2017
Patch file - fvdw-sl-17.0-patch04-25jan2018


Can you help me.

Thanks

KiKo

Hi KiKoVasques,

Please to post these outputs, with your USB disk plugged

Code: Select all

fdisk -l /dev/sdb      (if it is a disk size <2TB)
gdisk -l /dev/sdb           (if it is a disk size >2TB)

Check also how the disk is mounted by the firmware

Code: Select all

mount

So unplug the disk and enable the debug mode

Code: Select all

debugon

. Do a hot-plug again, wait around 30'' and post

Code: Select all

cat /var/log/messages

Note: think to disable the debug mode after running these commands !

Code: Select all

debugoff

Hi Jocko

I ran the commands fdisk e gdisk and both saw the disk. The mount command contain only sda disk.

I'm remotely and only tomorrow I will have a partner on site to unplug/plug the disk and post the content of the messages file.

Bellow the result of the fdisk and gdisk commands:

Code: Select all

root@ESTILLO_NAS:/ # fdisk -l /dev/sdb

Thanks

Thank.

Now we now at what step, attach event fails. It seems that ntfs-3g driver fails to mount the NTFS partition of your disk.

So see if we get more information on a manual command:

Code: Select all

/bin/mkdir -m 777 -p /mnt/MASA_USB_1
/bin/ntfs-3g /dev/sdc1 /mnt/MASA_USB_1

give also these output

Code: Select all

/sbin/vol_id -t /dev/sdc1
 file -bs /dev/sdc1


Note: please to use the BBcode 'code' when you paste some outputs (it is more readable)

[KiKoVasques]

Before I read your reply, I ran the ntfsfix command and it get many errors.

Comparing $MFTMirr to $MFT... FAILED

At night I will restart the NAS to see that the disk mount automatically.

[Jocko]

Indeed, if there is an unreliable file system, ntfs-3g will fail to mount it.

Please to note, this driver supports partially NTFS journaling and then if you unplug the disk whereas file system in an inconsistent state, you corrupt the fs on it and you need to plug it on your Windows laptop to restore it. To avoid this you need to use the safe remove feature of the usb-disk menu before unplugging physically the disk.

[KiKoVasques]

Grateful for your guidance.

One more question:
Can I choose the mount location or should I use symbolic link ?

Thanks for all

KiKo

[Jocko]

The firmware mounts it on a system folder and binds it on an additional mountpoint in the data volume (so in /share/1000 if you have a nwsp2). Then the firmware creates an 'USB' share and you can manage user access like the other shares.

You should not change this behaviour;
