LVM error

Hi Admins,

I have extended 64 MB LV to 100 MB.The same has been done with below error.


lvextend -L 100 /dev/vg00/lvname
Warning: rounding up logical volume size to extent boundary at size "112" MB.
Logical volume "/dev/vg00/lvname" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

lvdisplay tells the LV has been extended with new value ie, 112 MB

But when i mounted ,it shows the same old value..not extendde one..

what will be the issue..


Regards
himacs

Re: LVM error

Hi:

You can 'lvextend' the logical volume all day long, but until you expand/extend the _filesystem_ within you will not see your additional space when you mount the filesystem.

If you have OnlineJFS, you can 'fsadm' the filesystem online. Otherwise, unmount the filesystem and use 'extendfs'. See the manpages.

Regards!

Re: LVM error

exactly what J R F says. I attached a real example , I extended /home directory/FS :

# lvextend -L 522 /dev/vg00/lvol4 /dev/dsk/c3t5d
Warning: rounding up logical volume size to extent boundary at size "528" MB.
Logical volume "/dev/vg00/lvol4" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.con
f
# umount /home
# extendfs /dev/vg00/rlvol4
# mount /home
# bdf /home

Re: LVM error

Hi,
After lvextend you need to apply these command extendfs or fsadm .

see the example in man page of lvextend

Re: LVM error

Hi himacs,

This is a warning that lvm will extend the lvol to the next multiple you specified in relation to the PE size. The default size of PE is 4MB.

You can extend mounted VxFS file systems using the fsadm command if onlineJFS is installed.

Re: LVM error

Hi,

You need to extened the file system.

#/sbin/extendfs -F vxfs /dev/vg00/r{lvname}

example -
#/sbin/extendfs -F vxfs /dev/vg00/rlvol8

Ensure the filesystem now reports to be the new size
