Ciao a tutti..vi chiedo un aiuto
Ho bisogno di creare degli snapshop del mio server Linux, tramite LVM
Al momento la situazione è questa:
Codice:
root@centOS8:~# df -h
File system Dim. Usati Dispon. Uso% Montato su
devtmpfs 363M 0 363M 0% /dev
tmpfs 379M 0 379M 0% /dev/shm
tmpfs 379M 39M 341M 11% /run
tmpfs 379M 0 379M 0% /sys/fs/cgroup
/dev/mapper/cl-root 46G 4,5G 42G 10% /
/dev/sda1 976M 247M 663M 28% /boot
tmpfs 76M 0 76M 0% /run/user/0
Codice:
root@centOS8:~# pvscan
PV /dev/sda2 VG cl lvm2 [<49,00 GiB / 0 free]
Total: 1 [<49,00 GiB] / in use: 1 [<49,00 GiB] / in no VG: 0 [0 ]
Codice:
root@centOS8:~# lvscan
ACTIVE '/dev/cl/swap' [3,17 GiB] inherit
ACTIVE '/dev/cl/root' [45,82 GiB] inherit
root@centOS8:~#
Codice:
root@centOS8:~# vgdisplay
--- Volume group ---
VG Name cl

Metadata Areas 1
Metadata Sequence No 3
VG Access read/write
VG Status resizable
MAX LV 0

Max PV 0

VG Size <49,00 GiB
PE Size 4,00 MiB
Total PE 12543
Alloc PE / Size 12543 / <49,00 GiB
Free PE / Size 0 / 0
VG UUID aeJ04H-2cQm-n1FE-ncQb-Novi-0XRh-TDCDfM
root@centOS8:~#
andando d eseguire:
Codice:
root@centOS8:~# lvcreate -L 8G -n bckimg cl
Volume group "cl" has insufficient free space (0 extents): 2048 required.
root@centOS8:~#
se ho capito bene, dovrei ridurre i miei volumi logici ?
