Hi there,

Please forgive me for asking what is likely a recurring question. I have a CentOS 5.8 Guest OS on top of a Windows 7 host. I successfully increased the size of the drive from 15GB to 60GB but, now I am unsure how to exactly proceed to enable the Linux OS see this additional space? I am pretty new to Linux disk management, and although I have spent time looking online, and in this forum, I have not seen a disk partition setup the same as mine? I would really appreciate some guidelines please?

I downloaded the current version of gparted live, and added a CD Drive to the VM Host. I then rebooted and went through all the screens to get to the main gparted application menu. I have my current configuration of my drive as follows:

/dev/sda (60.00 GiB)

Partition File System Mount Point Label Size Used Unused Flags
/dev/sda1 ext3 /boot 101.94 Mib 36.25 Mib 65.70 MiB boot
/dev/sda2 (yellow padlock) lvm2 pv VolGroup00 15.24 GiB 15.24 GiB 0.00 B lvm
unallocated unallocated 44.66 GiB --- ---

I am unsure why I am getting the yellow padlock? I am booted up off the Live gparted so there must be something wrong here?

Any help would be very much appreciated!
Thank you,
Mark

Download GParted Live CD ISO, boot the VM from it, use it to resize guest partitions to fill the new unpartitioned space.

Thank you for the response.

That worked great! I was expecting this to be more complex, but it went smoothly!

I guess I spoke too soon! I just ran out of disk space.

This is what I have now:

Partition File System Mount Point Label Size Used Unused Flags
/dev/sda1 ext3 /boot 101.94 Mib 36.25 Mib 65.70 MiB boot
/dev/sda2 (yellow padlock) lvm2 pv VolGroup00 15.24 GiB 15.24 GiB 0.00 B lvm
/dev/sda3 ext4 44.66 GiB 897.47 MiB 43.78 GiB

I need to install a large app from my home directory, but just run out of space? How do I use this new storage? Even though I should be booted from the Live gparted iso, it looks like the /dev/sda2 partition is still locked? Does this mean that it is still mounted?

Thanks,
Mark

If the VM drive is virtual (not accessing a real host partition) then it can't be locked if the VM is booted from a live CD.

Best guest is that you aren't writing to the correct partition (your additional space seems to have been allocated as a new partition, not an enlarged existing partition).

Also I see now that your partition list mentions LVM, which is never a good sign. A simple legacy MBR partitioning system is better if you need to tweak things after the fact like this. Unfortunately I can't tell you how to solve this as I've never used LVM: perhaps someone else can suggest something.
