warning!! in lvextend

[Jairo Campana]

as it is limits ?
I can have problems ?

nms1 # lvextend -L 1750 /dev/vg00/lvol11
Warning: rounding up logical volume size to extent boundary at size "1752" MB.
Logical volume "/dev/vg00/lvol11" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

Nope - will cause you no problems.

If you have Online JFS and you're about to fsadm the filesystem, just remember that you'll be doing:

fsadm -F vxfs -b 1794048

where 1794048 = size of lvol (1752, the rounded up size) * 1024

Jairo,

This is simply a reminder that lvm will extend the lvol to the next multiple you specified in relation to the PE size. The default PE size is 4mb. Since you specified 1750 which is not a multiple of 4, lvm is telling you that the size will actually be 1752mb. You wouldn't be able to allocate 'part' of an extent. Nothing to worry about here.

Regards,
Eric

No Problem It's just a warning mesage.

-USA..

Nope just rounded up to the nearest 4Mb, bigger is better :-)

In addition ..
If you do not want to do the math you can use the "-l" option instead of "-L" option. The "-l" option let you specify the number of logical extend. Check lvextend man pages for details.

Another tip:

If you use the -L with lvextend, IE:

lvextend -L 4096 /dev/vg01/vlol9

then for fsadm, no need to calculate the kb's, just add a capital M:

fsadm -F vxfs -b 4096M /yuorfilesystem
