the data above is my actual problem in my customer. i want to ask help how can i extend my logical volume in mirror. im using hp-ux 11.11

[Johnson Punniyalingam]

>>>the data above is my actual problem in my customer.<<<

Above I ' am unable to see problem, above consider outputs of (file system , vgdisplay )

>>> i want to ask help how can i extend my logical volume in mirror. im using hp-ux 11.11<<<

I want ask you .? which file system / Logical volume you want to extend ..? hope you can help

[JMS G]

i want to extend the following volumes

dev/vgcare/lvoldic_idx 4096000 3586136 478004 88% /dic_idx

/dev/vgcare/lvoldic 4096000 3586136 478004 88% /dic

/dev/vg00/lvol4 20480000 19966184 513596 90% /Oracle

[Johnson Punniyalingam · Accepted solution]

>>>dev/vgcare/lvoldic_idx 4096000 3586136 478004 88% /dic_idx

>>>/dev/vgcare/lvoldic 4096000 3586136 478004 88% /dic

Above Logical volume exist under (VG = vgcare free space left in the volume group = 150 GB)

If I would consider "you have Online JFS" purpose of Online jfs you can extend the FS /LV on fly with out unmounting and no downtime required.
if you d'not have you need to unmount,lvextend,extenfs,mount, conserponding logical volumes.

#swlist -l product |grep -i JFS -> (check wether online JFS) Installed

# lvextend -L /dev/vgcare/lvoldic_idx
# fsadm -F vxfs -b M /dic_idx

(if d'not have Online jfs, stop all you application & Database ..etc..)

# unmount /File_system_name
# lvextend -L /dev/vgcare/lvoldic_idx
# extendfs -F vxfs /dev/vg00/rlvoldic_idx
# mount /dev/vgcare/lvoldic_idx /dic_idx



>>>>>/dev/vg00/lvol4 20480000 19966184 513596 90% /Oracle <<<<<<

here also procedure same as above mentioned, if you have online jfs you extendfs on fly, if not you need (down Oracle DB & application) and proceed to lvextend file system


Above Logical volume exist under (VG = vg00 free space left in the volume group = 37 GB)

if satisfied with answers. consider assign points , and close the thread

hi johnson, can u please check if this is correct.

/dev/vgcare/lvoldic_idx 4096000 3586136 478004 88% /dic_idx

umount /dic_idx
1. lvextend -L 20000 /dev/vgcare/lvoldic_idx
extendfs -F vxfs /dev/vgcare/rlvoldic_idx
mount /lvoldic_idx

umount /dic
2. lvextend -L 20000 /dev/vgcare/lvoldic
extendfs -F vxfs /dev/vgcare/rlvoldic
mount /dic

/dev/vg00/lvol4 20480000 19966184 513596 90% /Oracle

3. lvextend -L 19000 /dev/vg00/lvol4

extendfs -F vxfs /dev/vg00/rlvol4

mount /oracle

i need also to extend the volume for my /oracle

[Johnson Punniyalingam]

James Gulla>> u please also let know how much space you want to extend ..? is it about to (add by another 16GB space for ..?

/dev/vgcare/lvoldic_idx
/dev/vgcare/lvoldic


LV Name /dev/vg00/lvol4
LV Status available/syncd
LV Size (Mbytes) 20000

>>>>3. lvextend -L 19000 /dev/vg00/lvol4<<

you already have current (20GB) for /oracle..? why do need to extend with less size ..?

[JMS G]

i want to extend my /oracle up to 20 GB if possible in the same vg00
and extend my /lvoldic_idx and /lvoldic up to 20GB each if posible in the same vgcare group. can u please help me the exact command to apply this. thank you

[Johnson Punniyalingam]

>>>i want to extend my /oracle up to 20 GB if possible in the same vg00<<

means you want to add another (20GB) ..? if yes

# lvextend -L 40960 /dev/vg00/lvol4

# extendfs -F vxfs /dev/vg00/rlvol4

>>and extend my /lvoldic_idx and /lvoldic up to 20GB each if posible in the same vgcare group. can u please help me the exact command to apply this<<<


# lvextend -L 20480 /dev/vgcare/l/voldic_idx
# extendfs -F vxfs /dev/vgcare/rlvoldic_idx

# lvextend -L 20480 /dev/vgcare/lvoldi
# extendfs -F vxfs /dev/vgcare/rlvoldi


# mount -a
(will help to mount all the file system)

>>can u please help me<<

You can also help me to understand execution of commands by checking (man pages)

man lvextend
man extendfs
(Good examples are given)
