resize array
« on: April 20, 2011, 10:01:36 AM »
Helle people,

I'm running sme server 7.5.1. Some time ago I replaced the 80 GB drives with 500GB drives.
But now the array is only 80 GB instead of 500GB.

I executed the following commands
mdadm --grow /dev/md2 --size=max
pvresize /dev/md2
lvresize -l +100%FREE vg_primary/lb_root ( The first install was SME 6 I believe), so no main/root)
ext2online -C0 /dev/vg_primary/lv_root

But the Array stays 80GB.
What am I doing wrong?

lvresize -l +100%FREE vg_primary/lb_root

Should this not just be  "lvresize -l +100%FREE vg_primary/root"  ??

I did another  mdadm --grow /dev/md2 --size=max

But nothing showed up in /var/log/messages or the console.
