    How is life as a ‘free’ man? Are you less free now?

  5. avinash says:

    Today I “worked” from 9:00 to 17:00 with 1h of interruption to have lunch. So it seems that I am really less free…

    Hi,
    Geetanjalee here, your wife’s student of com.studies.
    You had a lecture yest. on Technology convergence, actually i read something in connextion with this subject. Well it is about texting to locate nearby friends. Umesh Chandra of the Nokia Research Centre in Palo Alto is building a network protocol that will enable basic phones to connect via sms with server on the cellphone network to find which of your friends are in the area. The system would use location information based on the nearest cellphone base stations to sent a response. It locate the sender to within 300 metres.
    It seems to be a great thing!!! i mean to me….

    Bonjour Mr, Je suis un de vos Ex élève de MCCI. J’ai un petit problème. J’ai un serveur sme qui a crash et j’ai besoin de récuperer les données dessus. J’ai tout essayé mais je n’arrive toujours pas à les récuperer. Je ne sais pas si vous pouvez m’aider. Laissez moi savoir. Merci et bonne journée.

    What have you tried? And what errors are you having? As far as I know, SME Server is based on CentOS Linux and, provided the disks are ok, you should be able to salvage the data.

    So I have done like it was told on
    http://pve.proxmox.com/wiki/SMEServer_LVM_Recovery_using_Knoppix_LiveCD#Taking_Remote_Control

    As they need a server to work, I have removed the crashed hard Disk and installed a fresh copy of SME on another hard disk so that they can continue to work. But on the crashed hard disk, there is 500GB of work that need to be recuperated. I have installed the hard disk on another computer, downloaded knoppix, run the live cd, accessed it through a putty SSH and followed the steps. It was told in the document to mount the hard disk. And then I can see only grud and lost+found folders and not the folders that I needed for backup.

  11. Bernard Commarmond says:

    if you want, I can meet you somewhere and bring the computer with me :)

  12. avinash says:

    Did you have the boot loader (grub) on a separate partition from the rest?

    Do a fdisk -l /dev/sdX and mount the partition containing the root of the disk. Use something like

    mount -t ext3 /dev/sdXN /mnt/folder

    Best tools i’ve used so far : spinrite

    was last year, hfs+ formatted drive, fully recovered.
    Also fails on another occasion, HDD was send to : http://www.krollontrack.com by post
    disk with data was back within one month, almost 12K spent, sent me back new hdd with all data as it were on the drive + old unused drive.

    Hope its of help to you guyz.

  14. Bernard Commarmond says:

    Here is the error that I have got with the command that you have sent me

    root@Microknoppix:~# fdisk -l /dev/sdX
    root@Microknoppix:~# mount -t ext3 /dev/sdXN /mnt/sdb
    mount: special device /dev/sdXN does not exist
    root@Microknoppix:~# mount -t ext3 /dev/sdb /mnt/sdb
    mount: wrong fs type, bad option, bad superblock on /dev/sdb,
    missing codepage or helper program, or other error
    In some cases useful info is found in syslog – try
    dmesg | tail or so

  15. avinash says:

    @Bernard,

    You did use /dev/sdb1 (or 2 or 3… depending on the partition) instead of /dev/sdXN (literally)? What message do you get?

  16. Bernard Commarmond says:

    I did finally make the backup of the disc drive. It was a Chinese puzzle. But in the end I found the solution. Thank you so much for your assistance.

    Here is the historical of the commands used:

    7 dmesg | grep sdb
    8 udevadm info –query=all –name=/dev/sdb
    11 mdadm –examine –scan /dev/sdb* >> /etc/mdadm/mdadm.conf
    12 /etc/init.d/mdadm start
    13 /etc/init.d/mdadm-raid start
    14 cat /proc/mdstat
    23 mount /dev/sdc1 /mnt/sdc1
    24 ls /mnt/sdc1
    25 cd /mnt/sdc1
    26 ls
    28 mkdir testArno
    29 cd testArno/
    32 /etc/init.d/lvm2 stop
    33 /etc/init.d/lvm2 start
    34 vgscan
    35 pvscan
    36 vgdisplay
    37 lvscan
    38 mkdir /mnt/data
    39 mount /dev/vg_primary/lv_root /mnt/data/
    40 ls /mnt/data/
    41 ls /mnt/data/home/e-smith/
    42 ls /mnt/data/home/e-smith/files/
    43 ls /mnt/data/home/e-smith/files/ibays/
    44 ls /mnt/data/home/e-smith/files/ibays/Primary/
    45 ls /mnt/data/home/e-smith/home
    46 ls /mnt/data/home/e-smith/files/
    47 ls /mnt/data/home/e-smith/files/users/
    48 ls /mnt/data/home/e-smith/files/users/admin/home/
    49 df /mnt/sdc1
    50 mkdir backupSME_Admin_Bernard
    51 cd backupSME_Admin_Bernard/
