Mounting after creating extent based mirroring not working

[edwin hamers]

The following is happening :

Server RP5470
HPux 11.11
sep 2002 patches

Created Volume group vg10, with two physical volume groups PVG1 en PVG2, which hold 3 scsi disk each, on different controllers.

Then i created 2 logical volume with lvcreate
lvcreate -D y -s g -L 15000 -m 1 -n lv10 /dev/vg10
lvcreate -D y -s g -L 15000 -m 1 -n lv11 /dev/vg10

If i try to mount lv10 this is what happens :
mount /dev/vg10/lv10 /u03
vxfs mount: /dev/vg10/lv10 is corrupted. needs checking.

So i checked with fsck :
fsck -F vxfs -o full /dev/vg10/lv10
file system is larger than device
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

If i mount /dev/vg10/lv11 then :
/dev/vg10/lv11: unrecognized file system
And if i fsck this one :
vxfs fsck: not a valid vxfs file system
invalid super-block
search for auxiliary super-block? (ynq)n
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

Does Anyone have an idea?

If I take you at your word, you have not yet run newfs (or mkfs) so that no filesystem exists on the LVOL.

I finally found out howto do it...

i had to newfs the logical volume but with the option for a rvol.
I just did not know that i had to use the character device ...

Thanx to all

where is the newfs?
