Accessing my cloudbox-slow blinking blue light

Your disc seems not dead, at least the partition table is accesible.
Lets try to assemble the raid array for the partition containing your files. Give this command

Code: Select all

mdadm --assemble /dev/md0 /dev/sda8

Now mount it

Code: Select all

mkdir /md0
mount /dev/md0 /md0

And list content

Code: Select all

cd /md0
ls -al

Post the output of this last command

I appear to be receiving some errors. Here is the output below.


root@fvdw-sta-kirkwood:/ # mdam --assemble /dev/md0 /dev/sda8
-sh: mdam: not found
root@fvdw-sta-kirkwood:/ # mkdir /md0 /md0

:disapprove
This is because you made an error in the command to assemble the raid arry
You should use "mdadm" and not "mdam".

[deepeedoubleu]

Sorry anout that. Unfortunately, it still cannot be found. Can I try something else?

root@fvdw-sta-kirkwood:/ # mdadm --assemble /dev/md0 /dev/sda8
-sh: mdadm: not found
root@fvdw-sta-kirkwood:/ #

Thank you

My fault we need upload mdadm first, give this command.
IMPORTANT REMARK
In this command replace "ip-pc" by the actual ip address of your pc running the fvdw-sl console (this ip is shown in upper right corner of the fvdw-sl main window

Code: Select all

tftp -r mdadm -l /bin/mdadm -g ip-pc
chmod 755 /bin/mdadm

After this mdadm command should work

Ps everytime that you reboot your cloudbox and upload the standalone kernel and you want to use mdadm you need to upload it as described in this post. This is because the standalone kernel and its prograns run from memory (RAM) which is erased when you reboot the cloudbox.

---edit---
With the last version 6.0, mdadm is no longer available with fvdw-sl console package. You need to use a new option via fvdw-programs menu, to get directly some advanced tools like mdadm :
* run on the telnet window the command: fvdw-sl-programs
(then a menu will appear)
* select "Upload and extract glibc mini and tools"

The fact that the raid array could be assembled is good, it means it is healthy and your data will be most probably ok. I need to do some reading on how to mount this array. In the past we did some work on repairing another cloudbox there we encountered also this problem with mounting. But I forgot how we solved it :scratch so need reread the info. This will be later this evening or in coming days as it is beautiful weather and mothers day and family goes first today. But Ivam quite sure we can rescue your data ;)

@fvdw,

To be able to mount data partition, deepeedoubleu should install xfs libs

About previous cases, the user needed to use xfs_repair to repair the fs

[fvdw]

@jocko, it is more complicated, seems we will need also LVM TOOLS for partition 8

Thank you all for your help. I am very patient. I wil do whatever i can to recover the data on this drive. Enjoy your day and please provide an update when you can.
