Editing Adaugare Disk (section)

=== Adaugare HDD ===

Procedam la introducerea noului disk virtual in hypervisor (ex Proxmox VM):

Fara a restarta masina virtuala si fara a fi nevoie de rescanarea interfetelor scsi, noul disk apare in OS:

<code class="mw-code mw-highlight plainlinks" style="display:block"><!--
--># lsblk
NAME                      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
......
sda                         8:0    0    20G  0 disk
├─sda1                      8:1    0     1M  0 part
├─sda2                      8:2    0   1.8G  0 part /boot
└─sda3                      8:3    0  18.2G  0 part

==== Partitionare si Formatare cu fisk====

Pentru partitionarea si formatarea sdb vom folosi in ceea ce urmeaza utilitarul fDisk. Comenzile introduse for fi marcate in <span style="color:#f00">'''bold'''</span>:

Atentie !!!<br>
Pentru partitioanarea si formatarea disk-urilor mai mari de 2TB se va folosii utilitarul Parted

==== Partitionare si Formatare cu parted ====

-->&#32;to be added
</code>

==== Adaugare disk la nivel de OS ====

Dupa partitionarea la nivel de disk, creem partitia la nivel de OS:

<code class="mw-code mw-highlight plainlinks" style="display:block"><!--
--># pvcreate /dev/sdb1
&#32; Physical volume "/dev/sdb1" successfully created.
</code>

Facem o noua listare pentru a fi siguri ca partitia a fost adaugata:

<code class="mw-code mw-highlight plainlinks" style="display:block"><!--
--># lsblk
NAME                      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
