Hello, I am trying to Resize my ext3 partition and I get the following message when trying to do so: “The file system is currently mounts on /. It is not possible to resize the file system while it is mounted. Unmount the file system and retry resizing.” Is there a way to add space to the partition without unmounting and if not, what would the process be to unmount and then re-size and then re-mount? Thanks, Andrew ---

Thanks, Andrew[/QUOTE] Hi Andrew All you need to do is boot from the install media in rescue mode (basically a live system) so all the partitions are unmounted, from here you can resize as required. What tools are you using? ---

Hello, Thanks for the information. I am just trying to use Partitioner in Yast. I was hoping there was a way to do this without having to go into Rescue mode, but if that is the only way then that is what I will do. Thanks, Andrew ---

[QUOTE=malcolmlewis;58525]Hi Andrew Well you could try an openSUSE Live version on USB?[/QUOTE] Extending LVM can be done live, but requires some additional info. @author, Please provide current pvs,vgs & lvs and which partition/disk you want to use to extend. ---

Hello, Where would I go to find the pvs, vgs & lvs? I am somewhat new to Linux. I am in the Partitioner and am looking the hard disks and I see the device and the two partitions but I don’t see this info under there. If I click on Volume Management, nothing is in there. Andrew ---

You need to get to the console/terminaland runthe following (won’t change anything): `pvs vgs lvs lsblk fdisk -l ` ---

It is partition 2 that I want to expand, sorry I did not include that. Andrew ---

You need to: 1. [Color=red] Backup ALL data, as the following step is quite dangerous if you make a mistake[/color] 2. Run: ```auto fdisk -l /dev/cciss/c0d0 ``` Verify that partition table is old style ‘Dos’ and [color=red]not GPT[/color]. 1. Now delete partition 2 and recreate it in one step ! ```auto fdisk /dev/cciss/c0d0 ``` Press ‘m’ for help. Press ‘d’ and select second partition Then press ‘n’ for new partition, ‘p’ for primary and select number ‘2’ for partition number. Select start sector to be ‘4209030’ and end → just press ‘Enter’ for the end of the disk . Last , but not least toggle the partition as bootable via ‘a’ flag. Last print via ‘p’ and confirm that Second partition has same attributes as before , and only the END is higher number. If anything differes - press ‘q’ to quit without any changes . If everything is the same and only the end is bigger - then press ‘w’ to write the changes. 1. Run partprobe to try to redetect the bigger partition: ```auto partprobe /dev/cciss/c0d0 ``` Run either ‘lsblk’ or ‘fdisk -l’ and verify that the new partition has been redetected. Otherwise reboot the system. 1. Extend your filesystem. As you got ext3, you can use: ```auto resize2fs /dev/cciss/c0d0p2 ``` [Color=red]As you will work with storage , Proper backup is needed. It would be easier if you got LVM , as it is quite flexible in that matter.[/color] Good Luck!
