LVM

Volné místo

pvs nebo vgs ukáže, jestli na physical volume nebo volume grupě je nějaké volné místo

Zvětšit logical volume

Mám srv_data_postgresql logical volume a chci mu přidat 50G.

lvextend -L+50G /dev/vg01/srv_data_postgresql

Size of logical volume vg01/srv_data_postgresql changed from 70.00 GiB (17920 extents) to 120.00 GiB (30720 extents).
Logical volume srv_data_postgresql successfully resized.

Přidat do logical volume všechno dostupné volné místo:

lvextend -l +100%FREE /dev/vg01/srv_data_postgresql

Nakonec natáhnout filesystem:

resize2fs /dev/vg01/srv_data_postgresql
