SUSE / Setting Up Bonding Devices

1. Run YaST > Network Devices > Network Settings.
2. Use Add and change the Device Type to Bond. Proceed with Next.
   
   
3. Select how to assign the IP address to the bonding device. Three methods are at your disposal:
   • No IP Address
   • Dynamic Address (with DHCP or Zeroconf)
   • Statically assigned IP Address
   Use the method that is appropriate for your environment.
4. In the Bond Slaves tab, select the Ethernet devices that should be included into the bond by activating the related check box.
5. Edit the Bond Driver Options. The modes that are available for configuration are the following:
   • balance-rr
   • active-backup
   • balance-xor
   • broadcast
   • 802.3ad
   • balance-tlb
   • balance-alb
6. Make sure that the parameter miimon=100 is added to the Bond Driver Options. Without this parameter, the data integrity is not checked regularly.
7. Click Next and leave YaST with OK to create the device.

How to create logical volumes in linux

This example procedure creates an LVM logical volume called new_logical_volume that consists of the disks at /dev/sda1, /dev/sdb1, and /dev/sdc1.

1. To use disks in a volume group, label them as LVM physical volumes with the pvcreatecommand.
   WARNING

   This command destroys any data on /dev/sda1, /dev/sdb1, and /dev/sdc1.

   # pvcreate /dev/sda1 /dev/sdb1 /dev/sdc1
     Physical volume "/dev/sda1" successfully created
     Physical volume "/dev/sdb1" successfully created
     Physical volume "/dev/sdc1" successfully created
   

2. #Another Example:
   
   pvcreate /dev/mapper/mpathx
   

3. Create the a volume group that consists of the LVM physical volumes you have created. The following command creates the volume group new_vol_group.

   # vgcreate new_vol_group /dev/sda1 /dev/sdb1 /dev/sdc1
     Volume group "new_vol_group" successfully created
   

   You can use the vgs command to display the attributes of the new volume group.

   # vgs
     VG            #PV #LV #SN Attr   VSize  VFree
     new_vol_group   3   0   0 wz--n- 51.45G 51.45G
   

4. Create the logical volume from the volume group you have created. The following command creates the logical volume new_logical_volume from the volume group new_vol_group. This example creates a logical volume that uses 2 gigabytes of the volume group.

   # lvcreate -L 2 G -n new_logical_volume new_vol_group
     Logical volume "new_logical_volume" created

5. 
   
   #Another Example:
   
    lvcreate -l 100%FREE -n new_logical_volume new_vol_group
   
   
   

6. Create a file system on the logical volume. The following command creates a GFS2 file system on the logical volume.

   # mkfs.gfs2 -p lock_nolock -j 1 /dev/new_vol_group/new_logical_volume
   This will destroy any data on /dev/new_vol_group/new_logical_volume.
   
   Are you sure you want to proceed? [y/n] y

   #Another Example:
   
   mkfs.xfs /dev/vgx/lgx
   mkfs.xfs /dev/mapper/vg..

   The following commands mount the logical volume and report the file system disk space usage.

   # mount /dev/new_vol_group/new_logical_volume /mnt
   # df

Extend lvm swap volume

To extend an LVM2 swap logical volume 

(assuming /dev/VolGroup00/LogVol01 is the volume you want to extend):

1. Disable swapping for the associated logical volume:

   # swapoff -v /dev/VolGroup00/LogVol01
   

2. Resize the LVM2 logical volume by 256 MB:

   # lvm lvresize /dev/VolGroup00/LogVol01 -L +256M
   

3. Format the new swap space:

   # mkswap /dev/VolGroup00/LogVol01
   

4. Enable the extended logical volume:

   # swapon -va
