It only takes a minute to sign up. However, when I perform lvextendI see that the changes are already applied to the partition as shown in Gnome Disks. So why do I still need to do resize2fs?
The lvextend command without the --resizefs option only makes the LVM-side arrangements to enlarge the block device that is the logical volume. No matter what the filesystem type or even whether or not there is a filesystem at all on the LV, these operations are always similar. Other filesystems may have their own extension tools. And if the logical volume did not contain a filesystem but instead something like a "raw" database or an Oracle ASM volume, a yet another procedure would need to be applied.
Each filesystem has different internal workings and so the conditions for extending a filesystem will be different for each. It took a while until a common API was designed for filesystem extension; that made it possible to implement the fsadm resize command, which provides an unified syntax for extending several filesystem types.
The --resizefs option of lvextend just uses the fsadm resize command. In a nutshell: After lvextendLVM-level tools such as lvsvgslvdisplay and vgdisplay will see the updated size, but the filesystem and any tools operating on it, like dfwon't see it yet. The LVM layer is just a container for the filesystem within. You can tell lvextend to resize the filesystem within the logical volume without having to run a separate resize2fs adding the -r or --resizefs option:. Because filesystems and logical volumes are different abstractions.
A volume is a chunk of disk like a partition — or at least, the "virtual" equivalent. It's just a block device. A filesystem is a structure that goes inside of that or, on top of it, if you prefer and which is used to provide a mapping between files and directories and so on to that device.
Without resize2fsthe partition is bigger, but the filesystem isn't taking advantage of the available space. You can actually create a filesystem initially which does not take up the entire partition.It is actually possible to reduce the size of a logical volume formatted with xfs filesystem using the following procedure :.
In this tutorial, we are going to show you how to reduce the size of a LVM partition formatted with xfs filesystem. We hope this tutorial was enough Helpful.Wh1000xm3 eq settings

The minimum value for sector size is ; the maximum is 32 KB.
Thanks for writing it. I was working toward accomplishing the same goal, but with a virtual disk, which offers greater latitude for easier solutions than a physical disk drive.

Currently  XFS Filesystems can't be shrunk. As a possible workaround in some environments, thin provisioned LVM volumes can be considered as an additional layer below the XFS filesystem. More details for the workaround would be very welcome. The link to redhat. Do let me know if this procedure was helpful. Arka Vansh Arka Vansh 1. XFS filesystems can't be reduced in size.

Parted tool doesn't support xfs. You need to modify the partition table to take advantage of the space provided by the LUN expansion. With fdiskthat's normally a deletion of the partition and recreating it with the same start point and new end point.
The same is probably true on the parted side. The XFS growth tool only works on mounted filesystems. Sign up to join this community. The best answers are voted up and rise to the top.

It is strongly recommended to use the YaST Partitioner to resize partitions or logical volumes. When doing so, the file system will automatically be adjusted to the new size of the partition or volume.
However, there are some cases where you need to resize the file system manually, because they are not supported by YaST:. After having manually resized partitions for example by using fdisk or parted or logical volumes for example by using lvresize. To avoid data loss, ensure that you back up your data before you begin any resizing task. The file system must support resizing to take advantage of increases in available space for the volume.
The utilities support increasing and decreasing the size as follows:. You can grow a file system to the maximum space available on the device, or specify an exact size. Ensure that you grow the size of the device or logical volume before you attempt to increase the size of the file system. When specifying an exact size for the file system, ensure that the new size satisfies the following conditions:. The new size must be greater than the size of the existing data; otherwise, data loss occurs.
The new size must be equal to or less than the current device size because the file system size cannot extend beyond the space available. When decreasing the size of the file system on a device, ensure that the new size satisfies the following conditions:.
If you plan to also decrease the size of the logical volume that holds the file system, ensure that you decrease the size of the file system before you attempt to decrease the size of the device or logical volume. Decreasing the size of a file system formatted with XFS is not possible, since such a feature is not supported by XFS.
The size of a Btrfs file system can be changed by using the btrfs filesystem resize command when the file system is mounted. Increasing and decreasing the size are both supported while the file system is mounted.
Change the size of the file system using the btrfs filesystem resize command with one of the following methods:. Replace SIZE with the desired size in bytes. You can also specify units on the value, such as K kilobytesM megabytesor 2G gigabytes.
The Disk Free df command shows the total size of the disk, the number of blocks used, and the number of blocks available on the file system. The -h option prints sizes in human-readable format, such as 1K, M, or 2G. Reducing the size of an XFS file system is not possible. The following example expands the size of the file system to the maximum value available.Only unencrypted Ext4 and XFS file systems can be extended, not vfat.
Note1: In this tutorial, the lvextend and lvreduce commands are used to respectively increase and decrease the size of a logical volume. Note: The file system is automatically extended -r without any need to unmount it. Note1: The file system is automatically extended -r without any need to unmount it.

You have to back it up with tar or another tooldrop it and recreate it. Example : shrinking the log. When extending the log. You can try. Concerning the second point, you are specifying an absolute size smaller than the current one. I have seen some of the sample questions where a floating range was mentioned.
For instance, increase lv to M and the size of the floating range should set between M and M. Hi CertDepot First of all, thank you very much for your efforts. I need to know three things.Wpf sidebar navigation
Same was mentioned by Sander in one of his videos. Can you please confirm this? It will not be possible to reduce any of them. In that case, if available disk space is not enough to complete a given task, then the only solution will be to delete swap partition and then vgreduce, do the task and make the remaining space as swap. In case if it is in the exam objectives and the root partition is ext4 with free space.
Can you please give a quick way to reduce the size of the root partition. Although, I have done it but still need to know if a quicker and better way is possible. This is not part of the exam objectives the root partition is a special case. Thank you very much for your reply and confirmation. I have successfully reduced Ext4 root logical volume without any rescue disk and following is my procedure. Run resize2fs on root file system reduce to 3GB in my case.

Is it really necessary to convert the partition into lvm before join them to a volume? Sorry to get back to the subject.
