Step Past Times Pace Deed Lvm ( Vg-Volume Grouping , Pv-Physical Voulme As Well As Lv- Logical Volume) To Approximately Other Linux Organisation

LVM Move: - We tin motility entire LVM Volume grouping to approximately other Linux System. 
It may require when yous are going to upgrade your electrical flow OS to the latest or at that spot is approximately lawsuit alongside electrical flow Server hardware or going to role novel server hardware.

Why Move LVM: -
1- There is approximately hardware lawsuit alongside electrical flow server
2- We convey novel Server hardware
3- Current OS is onetime version

Prerequisites:- 
1- Influenza A virus subtype H5N1 user alongside sudoers access over onetime System
2- user alongside sudoers privileges over novel System
Move LVM: - We need to perform next steps to motility LVM

My Current scenario as follows:
VG Name:  VG01

PV Name:  /dev/sdb1 in addition to /dev/sdc1 

LV Name:  LV01 in addition to LV02 

 Note: -first, brand certain no i is accessing the file on the active book inwards the book grouping nosotros are going to move.
Step 1: -  Unmount LV logical volume
Before, nosotros commence moving LVM necessitate to unmount let's role below ascendence to unmount LV

root@Server16: # umount /mnt/FLV

Step 2: - Make VG inactive 
Now nosotros necessitate to brand VG inactive, role below command.

root@Server16: # vgchange -a n VG01 

Step 3: - Export Volume Group

root@Server16: # vgexport VG01 Volume grouping VG01 is exported Cannot procedure book grouping VG01

After exporting VG, the Physical Volume volition exhibit upward equally beingness exported book grouping when yous volition execute command pvscan.

Step 4: - Shutdown System in addition to unplugged disk
After System Shutdown unplugged both the disk. Let's role init 0 ascendence to shutdown system.

Step 5: - Plugged disk to novel organization in addition to ability it on 
After putting both the disk to the novel system, I am going to ability it on in addition to volition exhibit yous how to import Volume Group.
Disk , VG in addition to LV details equally follows:

Step 6: - VG Import 
After putting all the disk to novel organization nosotros necessitate to import Volume Group, let's role below ascendence to Import VG using ascendence vgimport

root@US16: # vgimport VG01   Volume grouping "VG01" successfully imported 

Step 7: - Activate Volume Group

After successful import of VG, We necessitate to active Volume Group using ascendence below

root@US16: # vgchange -a y VG01   ii logical volume(s) inwards book grouping "VG01" instantly active

Step 8: - Create mountain point 

Now Volume Group has successfully import in addition to activated, let's practise mountain betoken then nosotros tin mountain in addition to commence using Logical Volume.

root@US16: # mkdir /mnt/lvm1 root@US16: # mkdir /mnt/lvm2 

Mount betoken successfully created.

Step 9: - Mount Logical Volume

root@US16: # mount /dev/VG01/LV01 /mnt/lvm1/ 

Step 10:  Check onetime information of LV01 Logical Volume

Volume Group Import has done successfully, in addition to Logical Volume mounted equally well.

let's cheque existing information inwards the mounted LV.

Volume Group has successfully Imported to novel organization in addition to working equally expected. We tin brand fstab entry to mountain Logical Volume permanently.
Step 11: - Make Fstab entry to mountain LV permanently
Let's role below ascendence to mountain it permanently.

root@US16: # vi /etc/fstab

Append trouble below inwards the goal of fstab file

/dev/VG01/LV01  /mnt/lvm1       ext4    errors=remount-ro 0     0

Your fstab file looks similar below

Step 12: - Use ascendence mountain -a to apply changes
After making alter inwards fstab file nosotros necessitate to restart organization to apply changes, merely nosotros tin role ascendence mountain -a to apply changes without restart system.

root@US16: # mount -a

Logical Volume has been successfully mounted permanently.

!!!That's all close VG Moving!!!! Thank yous then much for reading.

root@Server16: # ifconfig br0       Link encap:Ethernet  HWaddr 08:00:27:ab:3c:75           inet addr:192.168.28.120  Bcast:192.168.28.255  Mask:255.255.255.0           inet6 addr: fe80::a00:27ff:feab:3c75/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:337 errors:0 dropped:0 overruns:0 frame:0           TX packets:141 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:30299 (30.2 KB)  TX bytes:17098 (17.0 KB)  enp0s3    Link encap:Ethernet  HWaddr 08:00:27:ab:3c:75           inet6 addr: fe80::a00:27ff:feab:3c75/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:398 errors:0 dropped:0 overruns:0 frame:0           TX packets:149 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:40161 (40.1 KB)  TX bytes:17866 (17.8 KB)  enp0s8    Link encap:Ethernet  HWaddr 08:00:27:9f:86:47           inet addr:10.0.2.5  Bcast:10.0.2.255  Mask:255.255.255.0           inet6 addr: fe80::a00:27ff:fe9f:8647/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:7 errors:0 dropped:0 overruns:0 frame:0           TX packets:15 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:1988 (1.9 KB)  TX bytes:1720 (1.7 KB)  lo        Link encap:Local Loopback           inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:65536  Metric:1           RX packets:80 errors:0 dropped:0 overruns:0 frame:0           TX packets:80 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1           RX bytes:5920 (5.9 KB)  TX bytes:5920 (5.9 KB)  root@Server16: # 

Step-6: Complete LXD configuration -
During the LXD configuration wizard  It volition inquire to configure brace interface, Select No when it inquire for auto too lead no to give brace interface manually.

root@Server16: # lxd init Name of the storage backend to exercise (dir or zfs) [default=zfs]: zfs Create a novel ZFS puddle (yes/no) [default=yes]? yes Name of the novel ZFS puddle [default=lxd]: zfs-pool Would yous similar to exercise an existing block device (yes/no) [default=no]? no Size inwards GB of the novel loop device (1GB minimum) [default=15]: 10 Would yous similar LXD to last available over the network (yes/no) [default=no]? no Do yous desire to configure the LXD brace (yes/no) [default=yes]? yes Warning: Stopping lxd.service, but it tin notwithstanding last activated by:   lxd.socket LXD has been successfully configured. root@Server16: # 

Configuration exercise has been completed successfully.


Step-7: Create your showtime Container using the command below.

root@Server16: # lxc launch ubuntu:xenial C1 Creating C1 Starting C1 root@Server16: # 

 

Your showtime container is ready, let's cheque container condition using ascendance bellow.

 

root@Server16: # lxc listing +------+---------+-----------------------+------+------------+-----------+ | NAME |  STATE  |         IPV4          | IPV6 |    TYPE    | SNAPSHOTS | +------+---------+-----------------------+------+------------+-----------+ | C1   | RUNNING | 192.168.28.121 (eth0) |      | PERSISTENT | 0         | +------+---------+-----------------------+------+------------+-----------+ root@Server16: # 

!!! Congrats, You bring successfully configured LDX hypervisor !!!

**Some other useful ascendance to operate amongst LXD**

1- Command  login to LXD container:

root@Server16: # lxc exec C1 /bin/bash root@C1: # 

2- By default you can't login to container using password from a remote PC because 

"PasswordAuthentication  no" not allowed from sshd_conf file. 

Let's modify this file to access via ssh from remote pc.

 

root@C1: # vi /etc/ssh/sshd_config

And modify passwordaAthentication file similar below.

# To enable empty passwords, alter to yeah (NOT RECOMMENDED) PermitEmptyPasswords no  # Change to yeah to enable challenge-response passwords (beware issues amongst # simply about PAM modules too threads) ChallengeResponseAuthentication no  # Change to no to disable tunnelled clear text passwords PasswordAuthentication yes  # Kerberos options #KerberosAuthentication no #KerberosGetAFSToken no #KerberosOrLocalPasswd yeah #KerberosTicketCleanup yeah  

Save file too restart ssh service.

root@C1: # /etc/init.d/ssh restart [ ok ] Restarting ssh (via systemctl): ssh.service.
