interleaving logical volumes

[Azieh Ndangoh]

Is there a possibility of interleaving logical volumes ?

[harry d brown jr]

Sure, but why bother? Then again, what is your definition of "is", no just joking. Seriously, what you you mean by "interleaving"?

Does "interleaving" to you mean:

striping
extent striping
order of lvol's in a vg

??

I would say order of lvols within a vg

[harry d brown jr]

Sure, you can name them what ever you like and put them in any order, EXCEPT for / and /stand and maybe swap/dump.

Does your bdf look like this?

# bdf
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 204800 24187 169349 12% /
/dev/vg00/lvol1 299157 14835 254406 6% /stand
/dev/vg00/lvol8 774144 550621 210174 72% /var

/dev/vg00/lvol5 20480 1130 18145 6% /home

it could look like this:

# bdf

/dev/vg00/lvol1 299157 14835 254406 6% /stand

Actually what I meant by order would be to create a logical volume from another logical volume. Such that a hierachy exists

[Azieh Ndangoh]

I rephrase, can one create a logical volume from more than one volume group?!?

thanks

Definitely not with LVM, not so sure about VxVM, though...

[Jeff Schussele]

Nope....logical volumes cannots span volume groups.
And to anticipate...filesystems cannot span logical volumes.
