Mount

[Neil Shurven_1]

Hi
I have 2 disks "c0t4d0" and "c1t4d0" which where setup as mirrored dump
disks, plus mounted as /var/adm/crash.
I would like to separate the dump and crash devices.
I have created /dev/vg00/dump on c0t4d0 and /dev/vg00/crash on c1t4d0.(
lvcreate -l 2100 -n dump/crash -s y -C y -r n /dev/vg00 )
Then ran the lvlnboot -d dump /dev/vg00 - this has worked ok to create a dump
location.
When I run "mount /dev/vg00/crash /var/adm/crash" I
get "/dev/vg00/crash: unrecognized file system"

What Have I done wrong or forgotten, I come from a Sun background and hence
working with Logical Volumes (LVM)is all new.
Any help would be appreciated.

thankyou

Because your disks are mimorring, in order to mount these disks, you should do
first:
# vgchange -y a /dev/vg00
# mount /dev/zzz after warse

Good luck

You are correct to want to separate your crash and dump spaces. The only step
you forgot was to lay a file system down on your logical volume.
newfs -F vxfs /dev/vg00/rcrash

or

mkfs -F vxfs /dev/vg00/crash

should work. Then don't forget to add the file system into /etc/fstab so that
it will mount automatically at boot.

You forgot the newfs -F ... command...

This works.
