NAS542 500 Internal Server Error on USB External Drive

sheshman

Hi,

I've NAS542, updated to latest version and did a factory reset after it(i bought as second hand that's why deleted everything with factory reset), so when i connect my 4TB western digital usb hard drive through front USB port, i can see my usb drive on external storage, opening file browser and clicking to my usb drive, then it waits for 5-6 seconds and returns 500 Internal Error.



Enabled SSH and connected to nas through ssh to see if there is a problem with file system, but "ls -l" returns nothing.

All other services works jut fine and i can use my usb hard drive on my windows & linux computers without any problem.

Any suggestions?

So you have to run 'ls -l' in that directory, to see it there are any symlinks pointing out of the filesystem, or strange names, or ... .

with your help,i've found the problem.

As you can see on screenshot it was returning I/O error for one of the folders on USB Drive, so it wasn't an important one i deleted with rmdir command, now it works perfectly.

Thanks for your time and support.

If you have the possibility, do a filesystem check on that volume. Deleting that directory might not have removed all corruption.

Perhaps the USB power is not sufficient to supply certain size of external USB storage, or had you already plugged in the external power and still fail as well?

good point i don't think it's power issue because when i go \\mynasip i can see external usb drive and files in it

what is the output of

pwd

ls -la

in the root of that mount?

This is the output of pwd-> ls -la

You are running 'ls -l' from the wrong place. The external disk is mounted in /e-data/<something>/ .

oh sorry about that, i'm rookie on unix based systems.

Here are the output of ls -la under /e-data

when i run ls it shows  "90aa2d877a5254732fba90420060a799" i believe it's my usb hdd because when i "cd 90aa2d877a5254732fba90420060a799" and "ls" i can show my folders in usb drive
