Problem description:

Default TurboTier data disk which 1 TB is full i.e 100%, or a larger deployment size is needed.

Filesystem: /dev/mapper/vg1-vol1Mounted on : /mnt/dataUse%: 100%

Cause

TurboTier store size is full

Resolution

When you need to increase the size of an existing disk in a Linux environment, follow these steps:

1. Increase Disk Size in VMware

Navigate to the settings of your virtual machine in VMware
Increase the size of the desired disk (for example, extend the disk as required)

2. Connect to the Linux Server

Use a terminal client like PuTTY to log in to the Linux server

3. Verify Current Disk Size and Structure

Run the following commands:

df -h

fdisk -l

lsblk

df -h: Displays disk usage and mounted partitions
fdisk -l: Lists all available disks and partitions

Standard Disk Expansion (For < 2TB or No Partition Limit Issues)

4. Resize the Physical Volume

pvresize /dev/sdb

(Replace /dev/sdb with the correct disk)

5. Extend the Logical Volume

lvextend --size +1.21T /dev/mapper/vg1-vol1

(or use +100%FREE to allocate all available space)

6. Resize the Filesystem

For ext4:

resize2fs /dev/mapper/vg1-vol1

For XFS:

xfs_growfs /dev/mapper/vg1-vol1

7. Verify the New Size

df -h

Additional Steps (For Disks > 2TB / MBR to GPT Conversion Required)

Follow these steps if the disk expansion crosses 2TB or partition limitations are encountered.

1. Unmount the Volume

umount -l /mnt/data

2. Convert MBR to GPT

gdisk
w
Y

3.Reload Partition Table

partprobe /dev/sdb
lsblk /dev/sdb

4. Grow Partition

growpart /dev/sdb 1
lsblk /dev/sdb

5. Resize LVM Physical Volume

pvresize /dev/sdb1
pvs

(Expected: Updated size with free space available)

6. Extend Logical Volume

lvextend -l +100%FREE /dev/vg/lv
lvs

7. Check Filesystem

e2fsck -f /dev/vg/lv

8. Grow Filesystem

resize2fs /dev/vg/lv

9. Remount and Validate

mount /mnt/data
df -h
lsblk

Adding an Additional Disk in Linux

Adding a new disk to your system involves initializing the disk and incorporating it into your volume group.

Shutdown the Virtual Machine
1. Power off the virtual machine before adding the new disk.
Attach a New Volume in VMware
1. Add a new virtual disk to the machine with the desired size (e.g., 400 GB).
Power on the Virtual Machine
1. Start the virtual machine and log in via SSH.
Identify the New Disk
1. Run the following command to identify the newly added disk:
  fdisk -l | grep -i /dev/sd
2. Example output:
  - Disk /dev/sdc: 400 GB, 400000000000 bytes
  - Here, /dev/sdc is the new disk.
Initialize the New Disk as a Physical Volume
1. Format the new disk for use with LVM:
  pvcreate /dev/sdc
Extend the Volume Group
1. Add the new physical volume to your existing volume group:
  vgextend vg1 /dev/sdc
Extend the Logical Volume
1. Allocate the free space to the logical volume and resize the filesystem:
  lvm lvextend -l +100%FREE /dev/mapper/vg1-vol1 -r
2. The -r flag automatically resizes the filesystem.
Verify the New Size
1. Check the updated volume and filesystem size:
  df -h vgs

Example for Adding a 400 GB Disk

For a scenario where you’ve added a 400 GB disk (/dev/sdc):

Initialize the disk:
pvcreate /dev/sdc
Extend the volume group:
vgextend vg1 /dev/sdc
Extend the logical volume and resize the filesystem:
lvm lvextend -l +100%FREE /dev/mapper/vg1-vol1 -r
Verify the size:
df -h vgs
