Subject: "Btrfs: device_list_add() should not update list when mounted" breaks subvol mount
Date: Thu, 11 Sep 2014 00:22:41 +0200 [thread overview]
Message-ID: <20140911002241.201bc6c2@datenkhaos.de> (raw)
commit b96de000bc8bc9688b3a2abea4332bd57648a49f breaks subvolume mount
on one of my systems. I've bisected a mount problem to this commit.
Situation is:
- one hdd with btrfs
- default subvolume (rootfs) is different from subovlid=0
- at boot, several subvols are mounted at /home/$DIR
after commit b96de000bc8bc9688b3a2abea4332bd57648a49f this is not
possible anymore. Trying to mount results in (example):
mount: /dev/sda1 is already mounted or /home/video busy
The output of btrfs show is curious too:
btrfs fi show
Label: none uuid: 43438ef5-adac-46a9-823e-14951ee6866a
Total devices 1 FS bytes used 150.05GiB
*** Some devices missing
Btrfs v3.16
As this is a laptop with only one drive bay, this was never a multi
device setup. I've two more systems with kernel version >3.17-rc3
running and no problem like this.
regards,
Johannes
