Topic: resize array

[wjp79]

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?

please post the output of

ok..

the resizing has failed.. I don't know why

now, please, do

Code: [Select]

mdadm --grow /dev/md2 --size=max

and then

Code: [Select]

mdadm --detail /dev/md2


[p-jones]

lvresize -l +100%FREE vg_primary/lb_root

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

mdadm --grow failed..

did you see any error?

[wjp79]

No. Is there a log file?

[Stefano]

take a look at /var/log/messages

[wjp79]

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

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