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

Key
         StartNode | forestroot | domainroot The node in the console tree where the search starts. forestroot = search using the global catalog.

-o                               The format used to display the search results.
                                    dn = distinguished name.
                                    rdn = relative distinguished name.

phpinfo - how to create info file?

PHP Info

This file can help you to identify which php modules/extensions installed and enabled on your server.
This solution very simple.
Step 1.
Connect to the server through SSH and be sure you have root credentials.
Navigate to public_html directory.
cd /home/websiteuser/public_html
Step 2.
Create file.
nano phpinfo.php
Copy to the file code below:


<?php  
phpinfo(); 
?> 
Save and quit from file editor.
Step 3.
Let's check file permissions and owner.

root@server [/home/ websiteuser/public_html]# ls -l | grep phpinfo
-rw-------  1 root  root      24 Jun  5 13:34 phpinfo.php

As you see, owner of this file root, because we created this file under user root.
Change ownership:
chown websiteuser.websiteuser phpinfo.php
Change permissions:
chmod 644 phpinfo.php

Step 4.
Browse to this file from browser.
http://websiteuser.com/phpinfo.php

Now you see information page of apache & php. All modules and extensions.

Service stuck in "starting" or "stopping" state.

Windows  Service stucking problem.

Many times, service stuck and we don't know what to do with this issue.
If your server is production and you can't reboot him right now, but you must start or stop the specific service - this post for you.


1. Open command prompt
Let's find your service and identify the PID.
If you already know the name of service, run next command:

sc queryex w32Time

and you will see PID number.
If you don't know name of the service, just run same command without name of the service.

sc queryex

you will see list of all services, just find what you need.

2. Let's kill the service.
Now you know PID of the service and let's kill him!

taskkill /f /pid 1132

That's all.

enJoY!
