I wanted to extend one VG to 100 gb and I run command lvextend -L+100G /dev/vg/home it sucessfully extended and gave me 250GB initially was 150 GB after that I run mke2fs -j /dev/vg/home it created 250GB but lost existing data about 100GB is lost any method to recover it?
View 2 RepliesI have a 100GB HD with FC13 installed, default layout with options suggested during installation. I recently purchased a SSD 120GB and move the data the old HD from it with dd if=/dev/sda of=/dev/sdb bs=1M. Since the SSD is 120 Gb, so I should have 20GB space not utilized.
After the moving,
# fdisk /dev/sda1
Disk /dev/sda: 128.0 GB, 128035676160 bytes
255 heads, 63 sectors/track, 15566 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

I know I have done this command on out Red Hat systems. But for some reason in CentOS its giving me problems. I am trying to add more space to / as its at 100% full. Not sure what filled up the 4G is assigned to it but I did load Virtualbox and a widowsxp system.
Here is what i have:
df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hdc3 4061572 4050416 0 100% /
/dev/mapper/rootvg-rvg_datalv

I know there are probably alot of threads about lvm however they aren't addressing my problem. I want to extend the PEs available in a VG. This VG already has LVs and those are active and mounted. From what I read from the manpages of pvresize this should be perfectly possible.
Code:
pvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it.
I did the following steps and wonder if anyone has the same issue. THe machine where I am talking about is an ESX VM.
1. Resized the vmdk in ESX (+1G)
2. Let the kernel reread the device geometry: echo 1 > /sys/block/sdc/device/rescan
3. fdisk shows me the new size... so far so good
4. I resize the partition using fdisk (remove, recreate) and gave it the 8e type (lvm)
5. wrote config to disk
6. executed partprobe
7. pvresize /dev/sdc
Here it goes wrong! Pvresize says in the verbose output it sees the same size however at the end it says the pv has been resized. I have seen when I put volumes "offline" using vgchange -a n vg on a test machine, and then try pvresize it seems to work ok. This is against what is in the manual as it says pvresize should work on online mounted volumes.
Currently, I am at 99% capacity with a 1TB hard drive (sda). I want to add an extra 2TB storage (sdc) by extending the current volume group using LVM.

I can see that it is extended from the LVM GUI (System - Admin - LVM). However, when I download anything, the system says I am still at 99% capacity.
Code:
[root@localhost /]# fdisk -l
Disk /dev/sda: 1000.2 GB, 1000203804160 bytes

View 5 Replies View RelatedI have a question regarding extending file system. We are using RedHat 4 with update 8.Is it possible to extend an file system with GFS file system type while at the same time the same file system that need to be extended is used as an NFS file system? Is it necessary to stop the nfs daemon before extending the GFS file system? If it is necessary to stop nfs daemon, what can happen if it is not stopped prior extending?

View 5 Replies View RelatedWhat I need is a program that will extend a X-windows display over a network, similar to nvidia's TwinView (which I am already using on the main machine for its 2 current monitors).However, I cannot use Xdmx (as suggested by all the threads I found), as I would like it not to require me to manually start the x server and viewer, and have all the machines must be running a *nix OS, which won't work for me, as the secondary machine is running windows.I would also like it to hopefully use VNC to share the desktop, as I would be connecting to it from a windows machine over ethernet.By "extend" I mean one that would, say, for example, add another X display with a given resolution and position and serve that over VNC. I have yet to find any programs that will do this.

View 3 Replies View RelatedI am fairly new to c++. There must be a better way to do the following?:- Say I have a base class, Pet. I have several child classes that extend from this, like Dog, Cat, Fish etc.
I have the following function, that returns a pointer to a new Pet:-
Code: Pet* addPetToVet()
{ //Do some stuff
return new Pet();
} This will return a pointer an instance of a pet object.
Now, if I want to interpret this pet as a dog or cat I have to do this:-
Code: Dog* dogA = static_cast<Dog*>(addPetToVet());
Cat* catA = static_cast<Cat*>(addPetToVet()); Is there a way around this? Casting seems lame. I cant write a function for each type of pet.
I have a system with a single disk that is partitioned as below:
1) hda
hda1 - boot partition - 0.3GB
hda2 - System - 15.7GB
There are 2 volumes on single group. The boot partion is a physical volume and the system is a logical volume. The disk has more room up to 40GB. How can I extend the logical volume. Tried system-config-lvm, but it does not gives the option.
Have VMWARE workstation 7. Have to extend partition /dev/sda1 mounted to /home/user
1. Originally /dev/sda was 10gb I've extended device via VMWARE to 30gb.
2. When I do: fdisk /dev/sda it tells me that /dev/sda 30gb
3. when I check: df -h /home
it shows 10GB
4. How I can make Linux see the 30gb at /home/user?
I'm running debian and used mdadm to setup up a raid 6 array with 4x1TB drives with roughly 1.86TB's available with lvm. Then I added 4x1TB drives to the array. So now I have an 8 drive raid 6 array with 5.+TB's available, the array sees all available space. The question is how do I extend the volume group so that it uses the whole raid and not just half of it. As of right now the volume group is only 1.86TB's.
