Hi
I am using oracle linux 6.4. My hard drive capacity is 500 GB. my filesystem size onbly 50GB. I would like to extend my filesystem size to around 100GB. I tried many codes but still I am not able.
this is the output of df -h :
Otherwise the free space may be unpartitioned and we need to take different steps.
Hi
Thanks for your reply. this is the output of the pvs. I don't have free spaces. I have tried your code before, but because of the freespace I won't be able to extend the filesystem size.
I appreciate if you help me.
Output of pvs :
Is Linux running in a virtual machine, or on the physical hardware?
Assuming the latter, it's likely that the remaining ~450 GB is unpartitioned, depending on what options you selected during the installation.
You can check in fdisk, or the graphical palimpsest partitioning tool, if you prefer. You can create a new partition of the required size.
For example, here's an example where I've created a new partition of 5GB from unpartitioned space on /dev/sda, using fdisk:
Code:

The partition table has been altered!
Calling ioctl() to re-read partition table.
Everything I typed is in red. You'll need to reboot to update the partition table.
Now run these commands, substituting volume, volume group, logical volume names and sizes for your own:
Code:
[root@admin ~]# pvcreate /dev/sda3 # <-- for me this is what is new, in blue, above
Physical volume "/dev/sda3" successfully created
[root@admin ~]# vgextend rootvg /dev/sda3
Volume group "rootvg" successfully extended

Filesystem at /dev/mapper/rootvg-rootlv is mounted on /; on-line resizing required
old desc_blocks = 1, new_desc_blocks = 1
Performing an on-line resize of /dev/mapper/rootvg-rootlv to 2367488 (4k) blocks.
The filesystem on /dev/mapper/rootvg-rootlv is now 2367488 blocks long.
If Linux is running in a virtual machine, you should add a new hard disk, then run the same commands for (probably) /dev/sdb.
Dear Scott
Thanks alot for your reply. I have followed your code for creating a new partition and I assigned +100G to this. everything was successfull and as you were requested to do a reboot to update the partition, I made a reboot. But I am not able to to access to my GUI. and I'm having an error that is :
Code:
****An error ocurred during the file system check.
**** Dropping you to a shell; the system will reboot
****when you leave the shell.
****Warning -- SELinux is active
****Disabling security enforment for system recovery.
**** Run 'setenforce 1' to reenable.
, I run the fsck but it is just hanging, showing pages like matrix and just passing numbers fast. I don't whats happened to my OS.
anyway, maybe I format my pc. But as you mention is it possible to just partition the freespace during OS installation. I want to install Oracle Linux 6.4
I haven't seen any pages during installation regarding to the partitions .
I really appreciate your help and support

Hi all,
Do i need to increase the logical volume each time i increase the filesystem?
or is enough to increase the filesystem and the logical volume get increase automatically?

Hello,
in one default UFS filesystem we have 8K block size (bsize) and 1K fragmentsize (fsize). At this scenary I thought all "FileSytem IO" will be 8K (or greater) but never smaller than the fragment size (1K). If a UFS fragment/blocksize is allwasy several ADJACENTS sectors on disk (in a ... (4 Replies)

Hi All,
I need to increase the filesystem of / and /var (two different slices)? Space will be coming from /home slice so I need to decrease it. Is that possible without reinstallation or in a single-user-mode?
