Erstellen des Stores mit LVMDie 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 Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Display 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. Display of discs Translations Ignore |

Code Block |
---|
language | bash |
---|
title | Partitioning with fdisk |
---|
| 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 3 - Hereinnahme in LVM - Device Erzeugen Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Create device for LVM |
---|
| # 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 4 - Volume Group anlegen Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Create LVM |
---|
| lvm vgcreate "vg_jtelshared" /dev/sdb1 |
|
Schritt 5 - Logical Volume anlegen Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Create LVM |
---|
| lvm lvcreate -l +100%FREE vg_jtelshared -n lv_jtelshared |
|
Schritt 6 - File System erzeugen Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Create file system |
---|
| mkfs.xfs -L data /dev/vg_jtelshared/lv_jtelshared |
|
Schritt 7 - Mount Point vorbereiten Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Prepare mount point |
---|
| mkdir /srv/jtel
mkdir /srv/jtel/shared
chown -R jtel:jtel /srv/jtel/shared |
|
Schritt 8 - Mount Point in fstab festlegen und mounten fstab Eintrag: Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | vi /etc/fstab |
---|
| vi /etc/fstab
...
(add the following line)
/dev/mapper/vg_jtelshared-lv_jtelshared /srv/jtel/shared xfs defaults 0 0 |
|
Und mounten: Translations Ignore |
---|
Code Block |
---|
| mount /srv/jtel/shared |
|
Schritt 9 - Zwischenergebnis prüfen
Translations Ignore |
---|
Code Block |
---|
language | bash |
---|
title | Check final result |
---|
| df -h |
|
Es sollte ein Eintrag für /srv/jtel/shared existieren mit entsprechend freier Platz. Install Samba and lsof Translations Ignore |
