Subject: how to delete a (hidden) snapshot from timeshift?
Date: Tue, 3 Sep 2024 15:23:16 +0200 [thread overview]
Message-ID: <20240903132316.GA20488@tik.uni-stuttgart.de> (raw)
I have upgraded Mint 21 to Mint 22 with "mintupgrade" (Ubuntu 22 based).
This calls timeshift and creates a btrfs snapshot which I wanted to delete
afterwards:
root@mux21:~# btrfs subvolume list /
ID 256 gen 102469 top level 5 path @
ID 257 gen 102467 top level 5 path @home
ID 367 gen 102260 top level 256 path local/home
ID 667 gen 102466 top level 256 path tmp
ID 682 gen 102445 top level 5 path timeshift-btrfs/snapshots/2024-09-03_13-00-02/@
root@mux21:~# btrfs subvolume del timeshift-btrfs/snapshots/2024-09-03_13-00-02/@
ERROR: Could not statfs: No such file or directory
root@mux21:~# btrfs subvolume del -i 682 timeshift-btrfs/snapshots/2024-09-03_13-00-02/@
ERROR: Could not open: No such file or directory
I have had to mount the / filesystem directly (no subvol) to remove this
timeshift snapshot:
root@mux21:~# lshd
Device Size Type Label Mountpoint
sda 30G ATA:GPT "VBOX_HARDDISK"
sda1 0G vfat /boot/efi
sda2 0G BIOS boot
sda3 29G btrfs /
root@mux21:~# mount /dev/sda3 /mnt/tmp
root@mux21:~# l /mnt/tmp/
dRWX - 2024-06-21 11:45 /mnt/tmp/@
dRWX - 2024-03-07 13:00 /mnt/tmp/@home
dRWX - 2024-09-03 13:00 /mnt/tmp/timeshift-btrfs
root@mux21:~# btrfs subvolume list /mnt/tmp
ID 256 gen 102473 top level 5 path @
ID 257 gen 102471 top level 5 path @home
ID 367 gen 102260 top level 256 path @/local/home
ID 667 gen 102471 top level 256 path @/tmp
ID 682 gen 102445 top level 5 path timeshift-btrfs/snapshots/2024-09-03_13-00-02/@
ID 684 gen 102470 top level 257 path @home/.snapshot/2024-09-03_1500.hourly
root@mux21:~# btrfs subvolume del /mnt/tmp/timeshift-btrfs/snapshots/2024-09-03_13-00-02/@
Delete subvolume 682 (no-commit): '/mnt/tmp/timeshift-btrfs/snapshots/2024-09-03_13-00-02/@'
Is there an easier way to remove hidden snapshots/subvolumes?
