Splitting vg00's lvols and disk order
Hi,
I have splitted vg00's logical volumes and then I noticed the current logical volumes reside in the alternate disk and the "b" lvols reside in the primary boot disk:
systemb:/:vgdisplay -v vg00| grep dev/disk
PV Name /dev/disk/disk2_p2
PV Name /dev/disk/disk7_p2
LV Name /dev/vg00/lvol9
VG Name /dev/vg00
--- Distribution of logical volume ---
PV Name LE on PV PE on PV
/dev/disk/disk7_p2 512 512 -
----------------------------------------------------
LV Name /dev/vg00/lvol9b
VG Name /dev/vg00
--- Distribution of logical volume---
PV Name LE on PV PE on PV
/dev/disk/disk2_p2 512 512
AFAIK, the splitting process should leave first disk (disk2_p2) with current lvols and mirrored disk (disk7_p2) with "b" lvols, shouldn't it?
Best Regards,

Re: Splitting vg00's lvols and disk order
Looking at the lvsplit(1M) man page, if you want particular disks to become the "b" lvols, you should configure PVGs and specify the PVG you want to become the "b" lvols when splitting.

Re: Splitting vg00's lvols and disk order
yes, I know, but so far, everytime I have splitted vg00's lvols, the "b" ones went with the mirror-alternate boot disk, so I thought this was the default behaviour. I would like to know why this is happening in this way. How does "lvsplit" choose the pairs lvol-disk ?
Best Regards,
