My share is gone.

[ressof]

Hi

My share is gone and I wonder if you can do a factory reset of the fvdw-sl firmware?

I don't have any importent things on the share.

When I run fdisk -l I get this output

Code: Select all

Disk /dev/mtdblock0: 0 MB, 512000 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/mtdblock0 doesn't contain a valid partition table

Disk /dev/mtdblock1: 0 MB, 4096 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/mtdblock1 doesn't contain a valid partition table

Disk /dev/sda: 2000.3 GB, 2000398934016 bytes

Hi ressof,

With fvdw-sl, there is no factory reset.

My share is gone

could you explain more please. is it happened after rebooting ?
(in this case, I think it is just because the data partition is no longer mounted)

I note that your nwsp2 uses a EFI GPT partition table. So you don't have to use fdisk but gdisk to get it:

Code: Select all

gdisk -l /dev/sda

[ressof]

Here is my result from the command

Code: Select all

GPT fdisk (gdisk) version 0.8.5

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

my /share/1000/ is empty

I have tried to get file permission with user nobody, maybe that have done something? I have noticed that some files belong to user nodbody that I havent altered.

So your partition table is still ok.

1/From putty, post this output

Code: Select all

mount

2/What it is your firmware version ?

3/ if you don't read this line in the mount output

Code: Select all

/dev/sda8 on /share/1000 type ext3 (rw,relatime,errors=continue,barrier=1,data=ordered)

do:

Code: Select all

mount /dev/sda8 /share/1000

and then you should see your shares in

Code: Select all

ls -al /share/1000/

Next step, we need to search why the firmware failed to mount sda8

[ressof]

message after mount command

Code: Select all

I get this message when I try the mount dev/sda8 command

Code: Select all

mount: block device /dev/sda8 is write-protected, mounting read-only
mount: you must specify the filesystem type

and when I run mount again theres no sda8

should the owner and group of /rw_fs be nobody:nogroup?

[Jocko]

I get this message when I try the mount dev/sda8 command

Code: Select all

mount: block device /dev/sda8 is write-protected, mounting read-only
mount: you must specify the filesystem type

This would mean that you are lost your fs on sda8 :cry:
So post the output

Code: Select all

file -s /dev/sda8

and try again to mount sda8 with this cmdline

Code: Select all

mount -t ext3 /dev/sda8 /share/1000

should the owner and group of /rw_fs be nobody:nogroup?

This is also not normal. What did you play with nobody account ?
(we will look at later this point)

[ressof]

Output of first command

Code: Select all

/dev/sda8: data

second command

Code: Select all

mount: wrong fs type, bad option, bad superblock on /dev/sda8,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


I played with to get btsync to work with another NAS, maybe run something that changes all files owner to root?

Thank you for your help

[Jocko]

it seems that your first super block is corrupted.

So post

Code: Select all

 mke2fs -n /dev/sda8

(DON'T FORGET the flag '-n' !) and

Code: Select all

 tune2fs -l /dev/sda8

[fvdw]

read this post
viewtopic.php?f=11&t=1739#p13159

probably you just need

Code: Select all

e2fsck /dev/sda8

[Jocko]

This will work only if the superblock is not corrupted.
