All Shares Gone - Lacie 5Big Network 2

[Jocko]

:scratch More and more amazing.

Please wait, This evening I go to test the binary on my side.

[winnt]

I'm using "fvdw-sl-console-5-3-15-1-18feb2014-64bits" with "UIMAGE-395-NWSP2CL-179-standalone"

[fvdw]

What does this command give as output

Code: Select all

busybox ldd /usr/sbin/mount

[winnt]

Code: Select all

root@(none):/ # busybox ldd /usr/sbin/mount
ldd: applet not found

[Jocko]

At least with version 6, all seems ok

Code: Select all

root@fvdw-sta-kirkwood:/ # tar -xvf mount.tar

-rwxr-xr-x    1 root     root         62872 Aug  7  2012 usr/sbin/mount


and by using /usr/sbin/mount

Code: Select all

root@fvdw-sta-kirkwood:/ # usr/sbin/mount --help
Usage: mount -V                 : print version
       mount -h                 : print this help
       mount                    : list mounted filesystems
       mount -l                 : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
       mount -a [-t|-O] ...     : mount all stuff from /etc/fstab
       mount device             : mount device at the known place
       mount directory          : mount known device here
       mount -t type dev dir    : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
       mount --bind olddir newdir
or move a subtree:
       mount --move olddir newdir
One can change the type of mount containing the directory dir:
       mount --make-shared dir
       mount --make-slave dir
       mount --make-private dir
       mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
       mount --make-rshared dir
       mount --make-rslave dir
       mount --make-rprivate dir
       mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .

So I advice to download the latest fvdw-sl console version

[winnt]

Okay, I might be having better luck with the new code. The new mount command has been running without error for over ten minutes so far. I also tried the native mount command and received a different error.

Code: Select all

root@fvdw-sta-kirkwood:/ # mount -o ro /dev/md4 /md4

I'll let it run and let you know what happens when it is finished.

Thanks.

[Jocko]

I'll let it run and let you know what happens when it is finished.

I don't understand you.

mount command should end quickly.

if it is not the case, you need to break it (Ctrl+c) and post the dmesg output

[winnt]

ctrl-c didn't stop it so I opened a new window. How much of the dmesg output do you want?

here is this output:

Code: Select all

root@fvdw-sta-kirkwood:/ # busybox ldd /usr/sbin/mount
ldd: applet not found

[Jocko]

:roll:
Well as you have opened another telnet window, do on it:

Code: Select all

dmesg

(and post all lines)
and

Code: Select all

ps -ef

if mount command is hanged, you should see a line with a command-line /usr/sbin/mount ...

if Yes, try to kill it : Note its PID value (should be on 2d column) and do

Code: Select all

kill -9 pidvalue

Note: if you closed the first window, mount command might be killed also by this way.

if Not, post also this output

Code: Select all

cat /proc/mounts

Well, after days and days of frantic searching on the Internet, I have finally landed on this forum. :-)
I see that my problem is common, but I'm going to summarize it:
I have a Lacie 5 Big Network 2, with 5 disks to 4TB in RAID 5 and yes, i'm a Mac user ;)
Everything worked perfectly, until a few days ago while erasing a bunch of files from a directory, the Nas disappeared.
Switch off and on again, and what I could see was that there was nothing in Share.
Tried to do the procedure recommended by Lacie, which allows you to restore the NAS to the factory settings, without losing data, and what I got is that now I no longer have the Network Disk and firmware capsules is back to the original v.2.3.
From the Dashboard can not create any Share (the button itself is ghosted).

I'm looking at every way to not to reformat all 5 disks that would result in the loss of all data (about 14TB sigh !!)
So I began to read this topic, but I admit to have confused ideas.
In the help file, it is highlighted in red the words "Important: all existing data on the disk will be lost if you use the installer".
I thought this fvdw-sl console also serve to retrieve the array, but if it destroys all the data contained in the raid, then maybe I need more. Is this assumption correct?

If this prg can awaken my 5Big2, you could kindly tell me what are the key steps?
Thank you very much
