Create the Store with LVM

It is recommended to create the STORE machine without the disk for the storage being mounted by the installation routines. 

Useful Commands

The following commands are useful to see the current configuration of the machine,

Translations Ignore


Code Block
languagebash
# Show free space on existing devices
df -h

# Show drives
ls /dev/sd*

# Show partitions
fdisk -l

# Show partitions
ls /dev/sd*

# Re-scan the SCSI bus
echo "- - -" > /sys/class/scsi_host/host0/scan

# View physical volumes managed by LVM
lvm pvs

# Display logical volumes managed by LVM
lvm lvs

# Display logical volume groups managed by LVM
lvm vgs

# Where is what mounted
mount


Some of the information above may be required to complete installation.

It is important to know where the disk to be used is, and where the space is. 

Usually, we recommend adding a second disk drive to the machine for the storage. 

The following assumes that the disk was added as /dev/sdb on the machine, and is not yet partitioned. 

If this is not the case, or the drive is not /dev/sdb or the space was added to an existing partition, then the commands below will have to be (carefully) modified to take this into account.

Creation Steps

Create a Partition


Translations Ignore


Code Block
languagebash
fdisk /dev/sdb
 
# --> Edit the partitions on /dev/sdb
 
n
# --> Create new partition
p
# --> New primary partition
1
# --> Create new partition 1 (view output at fdisk -1 above)
Enter
# --> Confirmation that the first available cylinder should be used
Enter
# --> Confirmation that the last available cylinder is to be used (gives the maximum size in total)
t
# --> Change partition type
8e
# --> Linux LVM
w
# --> When OK, write


Create LVM Physical Volume

This command creates a physical volume which can be managed by LVM.

The above commands will have created a partition /dev/sdb1. If you are working on a different partition, then modify accordingly.

Translations Ignore


Code Block
languagebash
lvm pvcreate /dev/sdb1


Create a Volume Group

This command creates a volume group called vg_jtelshared. The volume group can be expanded later, by adding more physical volumes. 

Translations Ignore


Code Block
languagebash
lvm vgcreate "vg_jtelshared" /dev/sdb1


Create a Logical Volume

Finally, a logical volume lv_jtelshared is created on the volume group which contains the aggregated space.

Translations Ignore


Code Block
languagebash
lvm lvcreate -l +100%FREE vg_jtelshared -n lv_jtelshared


Create File System

Now, the file system is created. Here we use xfs, though you can use something else if you really want.

Translations Ignore


Code Block
languagebash
mkfs.xfs -L data /dev/vg_jtelshared/lv_jtelshared


Prepare Mount Point

The data should be mounted to the directory /srv/jtel/shared.

The following commands prepare for this:

Translations Ignore


Code Block
languagebash
mkdir /srv/jtel
mkdir /srv/jtel/shared 
chown -R jtel:jtel /srv/jtel/shared


Add to fstab to Mount at Boot

The following adds a line to fstab to mount the file system at boot:

Translations Ignore


Code Block
languagebash
cat <<EOFF >> /etc/fstab
/dev/mapper/vg_jtelshared-lv_jtelshared /srv/jtel/shared        xfs     defaults 0   0
EOFF


Mount the File System

Translations Ignore


Code Block
languagebash
mount /srv/jtel/shared


Checks

Translations Ignore


Code Block
languagebash
df -h


This should show an entry for /srv/jtel/shared with the expected amount of free space.

Install and Configure Access to STORE

Install Samba

These commands install the samba server and client and lsof.

Enable and Start Samba

The following commands setup the SMB and NMB services to autostart, and start them.

Setup Access to the Samba Server

jtel User Access

The following command creates the smb credentials for the jtel user.

Code Block
printf '<password>\n<password>\n' | smbpasswd -a -s jtel


Further User Access

If necessary, add further users to samba - replacing password with the actual password for the user. Here, for example, the windows administrator user:

Finally, test the file mount from one of the other machines. Either by connecting to STORE, or by using the windows explorer to attach to \\acd-store\shared



Erstellen des Stores mit LVM

Die meisten Linux / CentOS Installationen von uns arbeiten mit LVM. Diese Anleitung beschreibt, wie die Rolle STORE auf ein System mittels LVM installiert werden kann.

Schritt 1 - Feststellen der aktuellen config

Sv translation
languagede
Translations Ignore
Code Block
languagebash
titleDisplay of discs
# Show free space
df -h
# Partitionen anzeigen
fdisk -l
# Show partitions
ls /dev/sd*
# If the disk cannot yet be seen, re-scan the SCSI bus
echo "- - -" > /sys/class/scsi_host/host0/scan
# View physical volumes managed by LVM
lvm pvs
# Display logical volumes managed by LVM
lvm lvs
# Display logical volume groups managed by LVM
lvm vgs
# Where is what mounted
mount

Die Informationen oben werden nun gebraucht. Die Konfiguration sollte geprüft werden, nicht das bereits ein LVM für das Storage vorgesehen ist.

Schritt 2 - Anlegen einer neuen Partition

Hier ist es erforderlich, dass man weiß, wo der zusätzlicher Platz zu finden ist. Es gibt 2 Varianten - entweder eine neue Platte, oder eine erweiterte Platte. 

In beiden Fällen, wird eine neue Partition angelegt. Hier in diesen Beispiel, wurde eine neue Platte genutzt, die auf /dev/sdb zu finden ist.

Die Befehle unten sowie die Partitionsnummer (bei einer vorhandenen Platte ist die Partition dann nicht mehr zwingend 1), entsprechend anpassen.
