extend - extending logical volume in ubuntu -


i have following problem. ' ve added 20gb ubuntu machine (from 20 40gb). fdisk -l command :

disk /dev/sda: 42.9 gb, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders, total 83886080 sectors units = sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x000881a0     device boot      start         end      blocks   id  system /dev/sda1   *        2048      499711      248832   83  linux /dev/sda2          501758    41940991    20719617    5  extended /dev/sda5          501760    41940991    20719616   8e  linux lvm  disk /dev/mapper/zabbix-root: 20.1 gb, 20124270592 bytes 255 heads, 63 sectors/track, 2446 cylinders, total 39305216 sectors units = sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x00000000  disk /dev/mapper/zabbix-root doesn't contain valid partition table  disk /dev/mapper/zabbix-swap_1: 1069 mb, 1069547520 bytes 255 heads, 63 sectors/track, 130 cylinders, total 2088960 sectors units = sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x00000000

i tried exteng command :

lvextend -l+20g /dev/mapper/zabbix-root

and got following

extending logical volume root 38.74 gib insufficient free space: 5120 extents needed, 5 available

can extend root 20gb more?

thanks

update

ok made cfdisk pvcreate , vgextend , lvextend , can see 40gb in volumegroup vgdisplay command.

next question is. how refresh info commands df etc.? df -h there still 19gb in here... ill send outputs lvdisplay,vgdisplay,fdisk -l, , df -h.

fdisk -l :

so figured out. @ first needed enlarge disk size in vmware enviroment. after needed rescan ubuntu server :

echo "- - -" > /sys/class/scsi_host/host#/scan

where # had replace numbers every host in scsi_host. able see added space in ubuntu command :

fdisk -l

in next step had prepare or format freespace using command :

cfdisk /dev/sda

-you can format u wish (also space) there new partition now. - in case : /dev/sda6

next step use pvcreate new partition :

pvcreate /dev/sda6

after done add existing volume group using :

vgextend vg_name /dev/sda6

and can extend logical volume using :

lvextend -l+20g /dev/zabbix/root

and if check fdisk -l there /zabbix-root +20gb :) bud dont forget use resize2fs let filesystem know there change. if u not u not able use new space.

resize2fs /dev/zabbix/root
