Název: Snapper pre root subvolume
Přispěvatel: snapper 17. 08. 2018, 08:11:47

Zdravim,

pouzivam btrfs a rozhodol som sa pre vytvaranie snapshotov pomocou nastroja snapper. Moj aktualny stav je, ze mam "/" v subvolume "root":

Kód: [Vybrat]

# btrfs subvolume list -a /
ID 257 gen 21096 top level 5 path <FS_TREE>/roota rad by som vytvoril konfiguracny subor v snapper-i ale to skonci s chybou:

Kód: [Vybrat]

# snapper -c root create-config /
Creating config failed (creating btrfs subvolume .snapshots failed).
# snapper -c root create-config /root
IO Error (subvolume is not a btrfs subvolume).
# snapper -c root create-config /root/
IO Error (subvolume is not a btrfs subvolume).
Vopred dakujem za rady.

When you create the config the .snapshots subvolume must not exist. Snapper will create that snapshot.

If it still fails please provide /var/log/snapper.log.

Create subvolume '//.snapshots'

In my situation it was selinux.

sestatus

setenforce 0
then try again. Be warned it will disable selinux until next reboot
