Can't mirror disk

[Stefalap]

We have VG00 configured with 11 LV.
I am trying to mirror each of them on the second disk and when i get to the LVOL9 i get the following error.


> lvextend -m 1 /dev/vg00/lvol9 /dev/dsk/c2t0d0

lvextend: Not enough free physical extents available.

Logical volume "/dev/vg00/lvol9" could not be extended.

Failure possibly caused by strict allocation policy




Here are some outputs that may help you

Need to add more disk to the VG, you ran out.

BTW, nice login name ;)

[Jeff_Traigle]

You have strict allocation set (this is default and a good thing), which means you can't mirror to a disk device that is already being used in the LV. In this case, you have 215 extents being used already so you can't use that device to mirror.

[Stefalap]

Thanks, Now i have to look at how to do this. :)

I am taking over this server, and from what i know this was mirrored before using the present disks.
Is this due to something that changed in hte config, or is this normal because there are more data on the server.

Jeff,

Can i move the 215 Extents back to c2t1d0?

then that would allow me to mirror it right?

Thanks

Hi,

Only the volumes that have "allocated LE=2*current LE", i.e. lvol1 till lvol8, are mirrored.

lvol9, lvol10 and lvol11 are not mirrored and also cant be "mirrored" because there is simply not enough diskspace to mirror them.

Well, with some reorganisation, you could probably get lvol10 or lvol11 mirrored, but not both and certainly not lvol9.

Greetz,
Chris
