Hi,
I had 4 (ide) disks in an array (and 1 vg) of which
one (hde) broke. As I was not too sure of the stability of the system, I decided
to do a dd of the disk byte by byte to another identical disk. After this was
done (with loads of sector unreadable errors) I replaced the old disk with
the new disk, rebooted the system and by all standards all seems well (see
below):
Unfortunately, only the /dev/tripserv_vol/docu
will mount well!
/dev/tripserv_vol/pages gives the following
error:
# mount /dev/tripserv_vol/pages /c
mount: you must specify the filesystem type # mount /dev/tripserv_vol/pages /c -t
ext3
mount: wrong fs type, bad option, bad superblock on /dev/tripserv_vol/pages, or too many mounted file systems Anyone have any ideas why it won't
mount?!
Cheers,
Robin Edgar
