Go back to the VirtualBox dashboard, right-click on the VM, select Settings and select Storage from the Settings window’s left column.Next we need gparted to modify our virtual disk vdi. To grow the root filesystem, we will be using gparted utility.To resize the root partition it is safer for us to turn off the Virtual Machine. The /(root) partition is the one that is supposed to grow in our case. ├─vg_srv4-LogVol13 (dm-0) 253:0 0 7.There’s a block device sda, 40G in size which is of the type It has been partitioned into sda1, of size 20G (on top of which sits the root filesystem) and the rest is unallocated.

If you do lsblk you will see partitions or lvms depending on if you are using partitions or lvm, you can have all parts if you don't use lvm or all lvms if you don't use partitions. Partitioning was necessary some time ago when linux could not boot from LVM, but now it can. If you want to avoid reboot you have to assign raw sda/b/c disk to volume group without partitioning it to sda1/2/3.

If you don't see it you have to play with these echo 1 and echo - commands.Īfter you see more space you can extend/add partition, then reboot, extend vg, extend lv and fs. Doesn't make sense to reboot before.įirst thing you should notice after rescan is bigger disk size in fdisk and in lsblk. However, reboot should be done after you extend last partition on the disk or add new partition. If you are using partitions then you have to reboot to use new space. Since question is for Centos 5 I would say no way. At some point after 2.6 kernel started supporting online reread of partition table of active disk. Centos 6 - not possible to update partition table of active disk online,Ĭentos 7 - it is possible to extend last partition with growpart or create new partition with fdisk and make it visible without reboot with partprobe.
