[HLUG] backup old disk

[Graham Cole]

Thanks John, it's about time I understood the partitions but "extended"
and "Linux LVM" are jargon I don't understand. Both seem to be big so
neither is a swap partition I guess.

~$ sudo fdisk -l /dev/hdc

Disk /dev/hdc: 20.4 GB, 20490559488 bytes
255 heads, 63 sectors/track, 2491 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1   *           1          31      248976   83  Linux
/dev/hdc2              32        2491    19759950    5  Extended
/dev/hdc5              32        2491    19759918+  8e  Linux LVM

This is what I got:

~$ sudo mount -t ext3 /dev/hdc2 /mnt/disk2
mount: wrong fs type, bad option, bad superblock on /dev/hdc2,
       missing codepage or other error
       (aren't you trying to mount an extended partition,
       instead of some logical partition inside?)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

:~$ sudo mount -t ext3 /dev/hdc5 /mnt/disk2
mount: /dev/hdc5 already mounted or /mnt/disk2 busy

Not busy!? I did umount and checked that /mnt/disk2 was empty. Can it be
busy while empty? Maybe it's something else and the error message is
garbled info
