I just came to the office and was reported that apache is not running on
one of my servers. I forgot the error on the screen (it was about the
hard disk). I just quickly restarted the machine. However, when booting
up I don't see the grub menu. Instead, it lead me directly to grub shell
(if that what is was called). I see grub> on the screen. I tried to
press tab twice to check available commands but it was very limited. It
seems the OS or the kernel was not booted at all.
This machine has no public ip so I'm not really thinking of a hacking
scenario though it was still possible.
I tried to get the hard disk, put it to an external enclosure and tried
to mount it to one of my Linux Machine. When I do "mount /dev/sda1
/mnt", it says "mount: you must specify the filesystem type" so I
command "mount -t ext3 /dev/sda1 /mnt", it says:
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
There's no error in dmesg but when I check syslog, it has the ff:
Jul 20 09:08:03 PHP kernel: hfs: unable to find HFS+ superblock
Jul 20 09:18:04 PHP kernel: VFS: Can't find ext3 filesystem on dev sda1.
Could it be that the partition is corrupted or damage? As of the moment,
I'm trying to mount the hard drive to verify files.
