I creat 4G of size lvm partition.
#df -h
/dev/mapper/lvtest-lv 4.0G 2.6G 1.3G 68% /mnt/lv
[snip]
then I use the command "lvextend" to add 800M capatity into the lvm.
but i also see the capatity is 4G by using df,lvdisplay show right information
#lvextend -L +800M /dev/lvtest/lv
Extending logical volume lv to 4.88 GB
Logical volume lv successfully resized
#df -h
/dev/mapper/lvtest-lv 4.0G 2.6G 1.3G 68% /mnt/lv
Does lvextend affect the logical volume ("partition") size or the
mounted filesystem? I think you'll need to run e2extend or other
fs-specific tool to expand the filesystem structures, which is what df
is reporting.
Cheers,
Phil
