I would like to define a filesystem restricted to one physical volume. I tried defining a logical volume first and then creating filesystem on it. For some reason, I cannot create extended file system on this volume, only non-extended, because the lv does not show up in the list of lv's in smitty for the extended filesystem creation menu item but shows up for "normal" filesystems. All of my current filesystems are JFS2.

I want to do this in order to

1. have all LV's on one physical volume
2. mirror this physical volume to my second disk. The disks are exactly the same

That means you did not select the right "Logical volume TYPE" when you create the LV.

Actually, I'd prefer using command line to create LV and FS.

1. # mklv -t jfs2 -y lv_name vg_name number_of_LV PV
2. # crfs -v jfs2 -d lv_name -m /mount_point -A yes
3 # mount /mount_point
4. # chown uid:gid /mount_point
5 # chmod xxx /mount_point
6. Mirror it.
# mklvcopy lv_name 2 mirror_PV
7. Synchorizne the copies.
# syncvg -v vg_name

Thank you.

I would like to mirror the whole disk at once. I un-mirrored to get rid of the LVs spilling over two disks. I will now follow your advice and recreate them on my primary but then mirror the whole VG as I did before, unless you advise against it.

Yes,

You can create the LVs in one PV and then mirror the whoel PV using mirrorvg. That will be easier.

Thanks very much for your help
