"unrecognized file system" after newfs.

[stephen peng]

Guys,
I've got following issue:
[RX6600_4][root][/dev/vgpeng]#newfs /dev/vgpeng/rpeng1
newfs: /etc/default/fs is used for determining the file system type
version 6 layout
1048576 sectors, 1048576 blocks of size 1024, log size 16384 blocks
largefiles supported
[RX6600_4][root][/dev/vgpeng]#mount /dev/vgpeng/rpeng1 /peng
mount: /dev/vgpeng/rpeng1 is an invalid operand
[RX6600_4][root][/dev/vgpeng]#mount /dev/vgpeng/peng1 /peng
/dev/vgpeng/peng1: unrecognized file system
[RX6600_4][root][/dev/vgpeng]#newfs -F vxfs -o largefiles /dev/vgpeng/rpeng1
version 6 layout
1048576 sectors, 1048576 blocks of size 1024, log size 16384 blocks
largefiles supported
[RX6600_4][root][/dev/vgpeng]#mount -o largefiles /dev/vgpeng/peng1 /peng
/dev/vgpeng/peng1: unrecognized file system

never seen that, what could this be?

hi

run fsck -F vxfs -o full /dev/vgpeng/lpeng1

Hi,

Well a guess.... Could there be something wrong with your "block" device file as the newfs argument with the "raw" device file seems to work. Probably your peng block device file is missing??

I just created this lv and newfs it, then it was told to be unrecognized, this confused me.

hi

what does the fstyp -v /dev/vgpeng/peng1 shows.

RX6600_4][root][/]#fstyp -v /dev/vg00/lvol7
unknown_fstyp (no matches)
[RX6600_4][root][/]#fstyp -v /dev/vgpeng/peng1
unknown_fstyp (no matches)

look like something was wrong.

cd out of the vg directory
try lvremoving your lvol
then recreate the filesystem:

mkfs -F vxfs -o bsize=8192,largefiles /dev/vgpeng/rpeng1

mkdir /a
mount /dev/vgpeng/peng1 /a

how's about:

add in /etc/fstab:

/dev/vgpeng/peng1 /peng vxfs delaylog 0 2


and :

mount /peng

Alzhy,
It works! How could this happen? It is a 11.31 box.
