How to resize logical volume in LVM


The server you are working on is using the Logical Volume Manager, which has been configured as follows:

Volume Group: vgData 
Logical Volumes: lvMYSQL / lvDATA

We need 512MB of extra disk space added to lvMYSQL but the problem is that there
is no more free space left on vgDATA. Please increase the disk space of lvMYSQL by taking 512MB from lvDATA

df -h


lvs 



umount -v /var/www/html/

Check everything is ok before doing anything : 

e2fsck -ff /dev/vgDATA/lvDATA 



vgdisplay


 lvdisplay


resize2fs /dev/vgDATA/lvDATA 1536M 

lvreduce -L -512M /dev/vgDATA/lvDATA 


lvdisplay



resize2fs /dev/vgDATA/lvDATA 
mount /dev/vgDATA/lvDATA /var/www/html
df -h


vgdisplay



lvextend -l +128 /dev/vgDATA/lvMYSQL 
resize2fs /dev/vgDATA/lvMYSQL 
df -h
