Creating the Store with LVM

Die meisten Most of our Linux / CentOS Installationen von uns arbeiten mit LVM. Diese Anleitung beschreibt, wie die Rolle STORE auf ein System mittels LVM installiert werden kann.installations work with LVM. This guide describes how to install the STORE role on a system using LVM.

Step 1 - Determining the current Schritt 1 - Feststellen der aktuellen config

# Show free space
df -h
# PartitionenShow anzeigenpartitions
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.

The information above is now needed. The configuration should be checked, maybe an LVM is already planned for the storage.

Step 2 - Create a new partition

Here it is necessary to know where to find the additional space. There are 2 variants - either a new plate, or an extended plate. 

In both cases, a new partition is created. Here in this example, a new disk was used, which can be found on /dev/sdb

Adjust the commands below and the partition number (for an existing disk, the partition is then no longer necessarily 1) accordingly.

Anzeige von DiscsDisplay of discs

fdisk /dev/sdb
 
# --> Edit the partitions on /dev/sda
 
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
 
reboot now

Schritt Step 3 - Hereinnahme Inclusion in LVM - Create Device Erzeugen

# Here is the previous edition of /dev/sd* --> this is the new record (the 1st partition on /dev/sdb, i.e. the second hard disk, newly created partition)
lvm pvcreate /dev/sdb1

Schritt Step 4 - Create Volume Group anlegen

lvm vgcreate "vg_jtelshared" /dev/sdb1

Schritt Step 5 - Create Logical Volume anlegen

lvm lvcreate -l +100%FREE vg_jtelshared -n lv_jtelshared

Schritt Step 6 - Create File System erzeugen

mkfs.xfs -L data /dev/vg_jtelshared/lv_jtelshared

Schritt Step 7 - Prepare Mount Point vorbereiten

mkdir /srv/jtel
mkdir /srv/jtel/shared 
chown -R jtel:jtel /srv/jtel/shared

Schritt Step 8 - Mount Point Set and mount the mount point in fstab festlegen und mounten

fstab entryfstab Eintrag:

vi /etc/fstab
...
(add the following line)
 
/dev/mapper/vg_jtelshared-lv_jtelshared /srv/jtel/shared        xfs     defaults 0   0

Und mountenAnd mount:

mount /srv/jtel/shared

Schritt Step 9 - Zwischenergebnis prüfenCheck interim result

df -h

Es sollte ein Eintrag für There should be an entry for /srv/jtel/sharedexistieren mit entsprechend freier Platz with corresponding free space. 

Install Samba and lsof

yum -y install samba samba-client lsof

Configure Samba

        write list = root
        create mask = 0664
        directory mask = 0775

    force group = jtel
    acl allow execute always = True

EOFF
sed -i -e "s/MYGROUP/WORKGROUP/g" /etc/samba/smb.conf

Setup SeLinux, jtel User access and Firewall for Samba

Replace <password> with the password for the jtel user:

setsebool -P samba_enable_home_dirs=on samba_export_all_rw=on use_samba_home_dirs=on use_nfs_home_dirs=on
printf '<password>\n<password>\n' | smbpasswd -a -s jtel
firewall-cmd --zone=public --add-port=445/tcp --add-port=139/tcp --add-port=138/udp --add-port=137/udp --permanent
firewall-cmd --reload

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

useradd -m Administrator
printf '<password>\n<password>\n' | smbpasswd -a -s Administrator

Test SAMBA

systemctl enable nmb
systemctl enable smb
systemctl start nmb
systemctl start smb

Manually link /home/jtel/shared

ln -s /srv/jtel/shared /home/jtel/shared

Test the file mount

# From the windows machines:
