Resizing a VMWare Virtual Hard Disk - Linux and Windows OS

http://hagaycarmi.wordpress.com/

*** As this procedure is risky DON’T forget to create a backup of the VM ***

Stage 1 – resizing the VMDK file

On windows:

1. Shutdown the VM.

2. Open CMD and browse to C:\Program Files\VMware\VMware Server

3. From the command prompt, run the command: vmware-vdiskmanager -x 20Gb -t 3 "C:\Users\Marcus\test-OS\ubuntu_test-0001.vmdk"
The last command will set the vmdk file to 20 GB.

On Linux:

1. Shutdown the VM.

2. Open console and browse to the VM directory (Usually under /vmfs/volumes/vol_name/VM_directory)
3. Execute the same command (vmware-vdiskmanager)






Stage 2 – Expanding VM OS File System

On Windows:

1. Boot the OS
2. Open CMD and run diskpart.exe to expand the NTFS File System: http://support.microsoft.com/kb/325590
3. Reboot the OS.
You can also boot the VM OS using Live CD with Gparted: http://gparted.sourceforge.net/livecd.php

On Linux:

1. Reboot with Live CD
2. Check FS integrity: fsck -n /dev/sda1
3. Drop the Journaling from the ext3 FS: tune2fs -O ^has_journal /dev/sda1
4. Use fdisk or parted command to expand the partition.
5. Reboot into Live CD once more.
6. Check FS: e2fsck -f /dev/sda1
7. Resize the ext2 to "fit" the partition: resize2fs /dev/sda1
8. Check FS again: fsck -n /dev/sda1
9. Create the Journal : tune2fs -j /dev/sda1
10. reboot

EMC Celerra IP Replication via CLI

PROD Name: SALMON
DRP   Name: PERCH
 
Create the trust (run on PROD & DRP): 
[root@SALMON nasadmin]# nas_cel -create PERCH -ip  172.17.0.22 -passphrase nasadmin
[root@PERCH nasadmin]# nas_cel -create SALMON -ip  172.17.0.27 -passphrase nasadmin
 
Check the trust:
[root@SALMON nasadmin]# nas_cel -list

Create FileSystem Checkpint on the PROD Source file system:
[root@SALMON nasadmin]# fs_ckpt  Figaro_Groups  -Create
[root@SALMON nasadmin]# fs_ckpt  Figaro_Users  -Create
 
Create the new destination file system on the DRP Celerra (must be the same size):
[root@PERCH nasadmin]# nas_fs -name Figaro_Users_REP -type rawfs -create samesize=Figaro_Users:cel=SALMON pool=clar_r5_performance
[root@PERCH nasadmin]# nas_fs -name Figaro_Groups_REP -type rawfs -create samesize=Figaro_Groups:cel=SALMON pool=clar_r5_performance
 
Create mount points for the new file system on the celerra DRP:
[root@PERCH nasadmin]# server_mountpoint server_2 -create /dst_users Figaro_Users_REP
server_2 : done
[root@PERCH nasadmin]# server_mountpoint server_2 -create /dst_groups Figaro_Groups_REP
server_2 : done
 
Mount the file system (read only):
[root@PERCH nasadmin]# server_mount server_2 -option ro Figaro_Users_REP /dst_users
server_2 : done
[root@PERCH nasadmin]# server_mount server_2 -option ro Figaro_Groups_REP /dst_groups
server_2 : done
 
Copy the CheckPoint from the Celerra Prod source to the Celerra DRP destination:
[root@SALMON nasadmin]# fs_copy -start Figaro_Users_ckpt1 Figaro_Users_REP:cel=PERCH -option convert=no,monitor=off
[root@SALMON nasadmin]# fs_copy -start Figaro_Groups_ckpt1 Figaro_Groups_REP:cel=PERCH -option convert=no,monitor=off
 
Verify the File transfer:
[root@SALMON nasadmin]# fs_copy -list
Local Source Filesystems
Id    Source          Destination     Status   %Remaining   CommState

221   Figaro_Groups_c Figaro_Groups_R started  100          transferring
 
Begin replication:
[root@SALMON nasadmin]# fs_replicate -start Figaro_Groups Figaro_Groups_REP:cel=PERCH
[root@SALMON nasadmin]# fs_replicate -start Figaro_Users Figaro_Users_REP:cel=PERCH
