Does RHEL 7 support online resize of disk partitions?

Environment

• Red Hat Enterprise Linux 7

Issue

• Both Xen and KVM support online resize of the virtual block devices that the virtual machines use.
• Unfortunately, since the partitions in the boot virtual block device are already in use, those can't be modified online and the virtual machine won't pick up the changes on the boot virtual block device without a reboot.
• We are looking for ability to dynamically increase a partitioned volume, is it possible to resize the disk partitions online in RHEL 7?
• We are unable to dynamically increase a SAN attached volume without taking the volume offline. When will this feature to Support online resize of disk partitions be available?

Resolution

The ability to resize a Logical Volume and filesystem has long been provided by Logical Volume Manager (LVM) by simply using the entire block device (/dev/sdx for example) as a Physical Volume in the LVM Volume Group. There is no need for the old style of partition. This would allow the Logical Volume and filesystem to easily be expanded.

As to older style partitions, this feature has been added in RHEL 7 current release with a feature request (RFE has been filed to add support for online resize of disk partitions to RHEL 7 in private Red Hat Bugzilla 853105). With this feature, it's possible to resize the disk partitions online in RHEL 7.

---

Warning: Online partition table resizing is not a recommended process mostly because the underlying layer of an active logical volume or filesystem that relies on that information is being modified. While it is possible to perform online partition resize operation, it is not recommended simply from a data integrity standpoint and not because it's not possible.

---

• In order to resize online a partition which is in use please observe the following steps:

• Modify the on-disk partition table as usual (e.g. by using fdisk command).
  • Delete the partition:
    Raw

    Command (m for help): d
    Partition number (1,2, default 2): 2
    Partition 2 is deleted
    

  • Re-create the partition with the new size:
    Raw

    Command (m for help): n

  • Commit changes to on-disk partition table:
    Raw

    Command (m for help): w
    The partition table has been altered!
    
    Calling ioctl() to re-read partition table.
    
    WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
    The kernel still uses the old table. The new table will be used at
    the next reboot or after you run partprobe(8) or kpartx(8)
    Syncing disks.
    

  • While on-disk partition table has been updated, observe that on-memory kernel partition table has not:
    Raw

    # partprobe 
    Error: Partition(s) 2 on /dev/vda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use.  As a result, the old partition(s) will remain in use.  You should reboot now before making further changes.
    
    # cat /proc/partitions | grep vd
     252        0   31457280 vda
     252        1     512000 vda1
     252        2   13631488 vda2
    

• Execute partx (provided by util-linux package) with --update option on the block device to update the in-memory kernel partition table from the on-disk partition table:
  Raw

  # partx -u /dev/vda
  

• Verify that in-memory kernel partition table has been updated with the new size:
  Raw

  # cat /proc/partitions | grep vd
   252        0   31457280 vda
   252        1     512000 vda1
   252        2   18874368 vda2
  

• Proceed with any further steps, in this example by extending the PV on the partition:
  Raw

  # pvresize /dev/vda2
    Physical volume "/dev/vda2" changed
    1 physical volume(s) resized / 0 physical volume(s) not resized
  
  # pvs
    PV         VG          Fmt  Attr PSize  PFree
    /dev/vda2  rhel_vm-205 lvm2 a--  18.00g 6.20g
  

Root Cause

• Changes to allow online resizing of in-use partitions are required in both kernel and userland.
  • RHEL7 kernels include the required changes to BLKPG ioctl from block: add partition resize function to blkpg ioctl to support BLKPG_RESIZE_PARTITION operation.
  • RHEL7 util-linux package includes partx and resizepart binaries, currently the only userland commands that support BLKPG_RESIZE_PARTITION operation of BLKPG ioctl.

Issues with VMware 8 wont run Kernel 3.8 wont let VMware 8 & 9 work

When I try to launch VMware workstation, I get the following error:

Before you can run VMware, several modules must be compiled and loaded into the kernel CANCEL / INSTALL

No errors, when I select INSTALL nothing happens just closes.
I install manually:

sudo apt-get install open-vm-tools open-vm-tools-dev open-vm-dkms open-vm-toolbox open-vm-tools-dev

But already installed to the latest versions.
I will start a bounty to fix this.

I have uninstalled and reinstalled all components, but same problem.
I have tried a different Kernel, but end up with the same problem.

Tried this as suggested: here

Using Virtual Ethernet Adapters in Promiscuous Mode on a Linux Host

VMware Workstation does not allow the virtual Ethernet adapter to go into promiscuous mode unless the user running VMware Workstation has permission to make that setting. This follows the standard Linux practice that only root can put a network interface into promiscuous mode.

When you install and configure VMware Workstation, you must run the installation as root. VMware Workstation creates the VMnet devices with root ownership and root group ownership, which means that only root has read and write permissions to the devices.

To set the virtual machine's Ethernet adapter to promiscuous mode, you must launch VMware Workstation as root because you must have read and write access to the VMnet device. For example, if you are using bridged networking, you must have access to /dev/vmnet0.

To grant selected other users read and write access to the VMnet device, you can create a new group, add the appropriate users to the group and grant that group read and write access to the appropriate device. You must make these changes on the host operating system as root (su -). For example, you can enter the following commands:

chgrp <newgroup> /dev/vmnet0

chmod g+rw /dev/vmnet0

<newgroup> is the group that should have the ability to set vmnet0 to promiscuous mode.

The command to run vmware workstations ads root is simple: user@user#:~$ sudo vmware start

If you want all users to be able to set the virtual Ethernet adapter (/dev/vmnet0 in our example) to promiscuous mode, run the following command on the host operating system as root:

chmod a+rw /dev/vmnet0

How To Hide & UNHIDE Hard disk Volumes By CMD Command

How To Hide and unhide the hard disk Volumes using CMD Commands :

    First check how many drives are there in my computer and then see which drive holds your secret files.Then make the drive to invisible by following the below steps of using cmd commands,

    start->run->cmd->DISKPART
    DISKPART>list volume (it list available partition volumes)
    select the volume by SELECT VOLUME 1or 2 ..
     Hide the selected volume by REMOVE LETTER C or D or... command.

Note :For Unhide the hidden drive use the command ASSIGN LETTER after selecting the hidden drive.


Now to unhide the partition:
Go to an elevated command prompt=run cmd.exe as administrator

Enter following commands:

DISKPART --- run the diskpart program
LIST DISK ---- list the disks in system
SELECT DISK n ----n is number of disk with hidden volume
DETAIL DISK ----- to make sure you got the right one
LIST VOLUME ------lists the volumes in the system
SELECT VOLUME n ----n is the number of the hidden volume
DETAIL VOLUME ---- to make sure you got the right one
ATTRIBUTES VOLUME CLEAR HIDDEN ---clear the hidden attribute
EXIT --- exit from DiskPart
EXIT --- exit from command shell

Later if you want to hide the volume again then the command is:
ATTRIBUTES VOLUME SET HIDDEN

How to format USB drive using Linux terminal ..

How to format USB with Linux terminal ..  

[ Formatting a USB in Ubuntu or linux is as easy as make filesystem (mkfs).
mkfs and tab will show you all the filesystem types you can use:

[anc@localhost~]$ mkfs
mkfs mkfs.ext3 mkfs.jfs mkfs.ntfs mkfs.vfat
mkfs.cramfs mkfs.ext4 mkfs.minix mkfs.reiserfs mkfs.xfs
mkfs.ext2 mkfs.ext4dev mkfs.msdos mkfs.udffs

To format a USB drive all you need to know is its name, this can be found by
typing df at a terminal:

[anc@localhost~]$ df -hT
Filesystem Type Size Used Avail Use% Mounted on
--snip
/dev/sdc1 ext3 3.6G 3.3G 134M 97% /media/disk


In the above example my USB is sdc1 and is a 4G USB stick. As you can see
I changed it from NTFS to ext3.

FAT32 and NTFS are weak filesystems, not only are they prone to losing data but also
require constant defragging. Most linux filesystems (except ext2) are journalled. Thye never require defragging and have better security- the disadvantage is that if you format a USB memory stick as ext3 it cant be read under windows.

To answer your earlier question,

mkfs.vfat /dev/sdc1
mkfs.ntfs /dev/sdc1

would make FAT32 and NTFS filesystems on a memory stick called sdc1

Hope that helps. ]
