Extend Volume Group and increase Logical Volume size + Resize Partition ( STEP BY STEP)

10 STEPS to add 10GB to LVM

1. Add size to the Virtual Disk in vmware. 

***for example let's add 10GB to filesystem*** REBOOT Guest after adding.(If needed)

2.Check if you got free space on physical disk.

[root@localhost ~]# sfdisk -s

/dev/sda: 20031488

3. Space need to be assigned to /dev/sda check whick sda partitions you already have and create a new one:

[root@localhost ~]# ls -al /dev/sda*

brw-rw---- 1 root disk 8, 0 Apr 1 2013 /dev/sda

brw-rw---- 1 root disk 8, 1 Apr 1 2013 /dev/sda1

brw-rw---- 1 root disk 8, 2 Apr 1 2013 /dev/sda2

We create new partition /dev/sda3:

[root@localhost ~]# fdisk /dev/sda

Command (m for help): n

Command action

e extended

p primary partition (1-4)

p

Partition number (1-4): 3

First cylinder (1306-1697, default 1306): Enter

Using default value 1306

Last cylinder or +size or +sizeM or +sizeK (1306-1697, default 1697): Enter

Using default value 1697

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

***REBOOT***

4. Check if new partition exists:

[root@localhost ~]# ls -al /dev/sda*

brw-rw---- 1 root disk 8, 0 Apr 1 2013 /dev/sda

brw-rw---- 1 root disk 8, 1 Apr 1 2013 /dev/sda1

brw-rw---- 1 root disk 8, 2 Apr 1 2013 /dev/sda2

brw-rw---- 1 root disk 8, 2 Apr 1 2013 /dev/sda3

5. Create a physical volume for LVM:

[root@localhost ~]# pvcreate /dev/sda3

Physical volume "/dev/sda3" successfully created

6. Assign the physical volume to the Volume Group:

[root@localhost ~]# vgextend VolGroup00 /dev/sda3

Volume group "VolGroup00" successfully extended

7. Check if you got free space on Volume Group:

[root@localhost ~]# vgdisplay

  --- Volume group ---

  VG Name               VolGroup00

  System ID

  Format                lvm2

  Metadata Areas        2

  Metadata Sequence No  5

  VG Access             read/write

  VG Status             resizable

  MAX LV                0

  Cur LV                2

  Open LV               2

  Max PV                0

  Cur PV                2

  Act PV                2

  VG Size               10.88 GB

  PE Size               32.00 MB

  Total PE              956

  Alloc PE / Size       956 / 10.88 GB

  Free  PE / Size       97 / 10.1 GB

  VG UUID               a8rsVw-ACdV-K5aP-uG7l-Nfvq-Wn9i-E36JE5

8. Extend volume:

[root@localhost /]# lvextend -L+10G /dev/VolGroup00/LogVol00

Rounding up size to full physical extent 10 GB

Extending logical volume LogVol00 to 20.88 GB

Logical volume LogVol00 successfully resized

9.Resize FileSystem:

[root@localhost ~]# resize2fs /dev/VolGroup00/LogVol00

resize2fs 1.35 (28-Feb-2004)

/dev/VolGroup00/LogVol00 is mounted; can't resize a mounted filesystem!

Cannot use resize2fs as it is online. Use ext2online instead. 

[root@localhost ~]# ext2online /dev/VolGroup00/LogVol00

ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b

10. Check if you resize success:

[root@localhost ~]# df -hl

Filesystem            Size  Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

                       21G   10.2G  9.6G  57% /

/dev/sda1              99M   13M   81M  14% /boot

tmpfs                1006M     0 1006M   0% /dev/shm

That's All. :)

Get mailbox size exchange 2007

How to get mailbox size in exchange 2007 via PowerShell.
Very simple!
1. If you need to check mailbox size for individual use string bellow:

Get-MailboxStatistics username | ft DisplayName, TotalItemSize, ItemCount
******for more information use get-help Get-MailboxStatistics -full******

2. If you need to get mailbox size for all user use next command:

Get-MailboxStatistics | ft DisplayName, TotalItemSize, ItemCount
******To export output to the file, add > c:\mailboxsize.txt******

FOR EXAMPLE:  Get-MailboxStatistics | ft DisplayName, TotalItemSize, ItemCount > c:\mailboxsize.txt

To view more friendly output you can try to use my string:

Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | ft DisplayName,@{label="TotalItemSize(MB)";expression = {$_.TotalItemSize.Value.ToMB()}},ItemCount > c:\mailboxsize.txt

:)

******If the command is not working run this before:******

add-pssnapin Microsoft.Exchange.Management.PowerShell.Admin
