I have a LV which has a striping over 7 disks.
. It is full now. Its VG also has 7 disks.

Now if I extend the VG with 2 disks and try to extend the LV what is the LVM error i WIll get.

Re: Lvm Error

hi,

if you use striping, for example with 7 disk ( across ) and them you like to add aditional disk you should recreate the whole LVOL.

backup data delete lvol and them create striped LVOL with for example 9 disk, and them create FS and restore data.

Re: Lvm Error

If you have LV striped over 7 disk you would need another 7 disk if you want to increase it.

and if u just want to add one disk simply take backup and recreated the LV striped over 8 disks and restore.

The error will probably say something about 'not enough free extents' because you don't have enough disks for the stripe.

Re: Lvm Error

If you are using extent base stripping you can extend the LV to another 2 luns without any recreation of LV.

Thanks Patrick,

Guys I just wanted the Error so that i can prepare a report for management.

Benoy>>>>Your answering is confusing. How can I extend the Striped LV on another 2 LUNS. I am sure its not possible.

Re: Lvm Error

I am 95% sure even if you say error would be

"I don think I can increase cause you do not have enough disk/space in VG"

They would not mind, at my side they just want a line to be filled in, let it be anything.....

No Points for this please (:

Re: Lvm Error

An Old thread but as you are just after the error that too for purely documentation purpose, this might work:
