Dear all,
a friend of mine runs a freenas box, it crashed.....
the problem is that the disk labels are gone and if i try to mount the hard disk i get this error: incorrect super block
if i try to fdisk the disk:
******* Working on device /dev/ad2 *******
parameters extracted from in-core disklabel are:
cylinders=969021 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=969021 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
no disklabels!
so you want to try fsck on the disk, i tried fsck_ufs:
** /dev/ad2
Cannot find file system superblock
ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: /dev/ad2: can't read disk label
does anyone have an idea how to fix it, if it is even fixable?
i hope it's enough info if you need more please ask
thanks.....
