lvextended size is not usable

[J.A.R. Karremans]

I have succesfully extended my mirrored logical volumes lvol10 en lvol11 to new and larger sizes on my mirrored disks.
But, alas, the new sizes 20GB and 2GB do not show up in bdf and are, also, not usable... What steps are missing, what did I do wrong?

One example:

lvsplit /dev/vg00/lvol10
lvextend -L 20000 /dev/vg00/lvol10 /dev/dsk/c1t15d0
lvextend -L 20000 /dev/vg00/lvol10b /dev/dsk/c0t10d0
lvmerge /dev/vg00/lvol10b /dev/vg00/lvol10
lvsync /dev/vg00/lvol10

bdf output:

/dev/vg00/lvol10 17408000 17029392 366834 98% /dbs1

vgdisplay -v vg00 output:

LV Name /dev/vg00/lvol10
LV Status available/syncd
LV Size (Mbytes) 20000
Current LE 2500
Allocated PE 5000
Used PV 2

Please advice!

You must also extend the filesystem on the LV.

assuming this is JFS, you have two possibilities :
. If you have online JFS, you can increase by "fsadm -b /dbs1
. It you don't, you must then stop all running process accessing this FS (fuser -cu /dbs1" may help), then use extendfs, then remount FS.

Hi Jan,
If it is not Online JFS then you have to do "extendfs".
