Hi, I have a raid1 filesystem:
Label: 'raid1pool' uuid: b97d3055-c60c-4f10-aa1b-bf9554f043c9 Total devices 2 FS bytes used 320.00KiB devid 1 size 2.00GiB used 437.50MiB path /dev/sdd devid 2 size 2.00GiB used 417.50MiB path /dev/sde It's mounted at /mnt2/raid1pool # mount | grep raid1pool /dev/sdd on /mnt2/raid1pool type btrfs (rw,relatime,space_cache) created a subvolume # btrfs subvol create /mnt2/raid1pool/share1 Create subvolume '/mnt2/raid1pool/share1' # btrfs subvol list -u -p -q /mnt2/raid1pool/ ID 261 gen 27 parent 5 top level 5 parent_uuid - uuid 0e31fe3c-d35d-d346-9560-b29b82ff384a path share1 created two snapshots(different destinations) like so: # mkdir -p /mnt2/raid1pool/.snapshots/share1 # btrfs subvol snapshot /mnt2/raid1pool/share1 /mnt2/raid1pool/.snapshots/share1/snap1 Create a snapshot of '/mnt2/raid1pool/share1' in '/mnt2/raid1pool/.snapshots/share1/snap1' # btrfs subvol snapshot /mnt2/raid1pool/share1 /mnt2/raid1pool/share1/snap2 Create a snapshot of '/mnt2/raid1pool/share1' in '/mnt2/raid1pool/share1/snap2' Then.. # btrfs subvol list -u -p -q /mnt2/raid1pool/ ID 261 gen 29 parent 5 top level 5 parent_uuid - uuid 0e31fe3c-d35d-d346-9560-b29b82ff384a path share1 ID 262 gen 28 parent 5 top level 5 parent_uuid 0e31fe3c-d35d-d346-9560-b29b82ff384a uuid 91354cbc-615f-be40-8afb-eb0c254157d8 path .snapshots/share1/snap1 ID 263 gen 29 parent 261 top level 261 parent_uuid 0e31fe3c-d35d-d346-9560-b29b82ff384a uuid d236544e-5044-c645-a0b7-440c15727d8e path share1/snap2 You see how the parent_uuids of both snapshots match the uuid of the subvolume(0e31fe3c-d35d-d346-9560-b29b82ff384a) but the parent ids don't match. I was hoping to see 261 as the parent id for both snapshots. Am I missing something or is this a bug in btrfs-progs?
