Subject: is mounting subvolumes with a read-only root subvolume allowed?
Date: Fri, 15 Nov 2013 00:32:10 +0100 [thread overview]
Message-ID: <20131114233210.GU30929@in.waw.pl> (raw)
Hi,
I have a box with / and /home being subvolumes from the same btrfs filesystem.
/etc/fstab:
UUID=c0686... / btrfs subvol=root,x-systemd.device-timeout=0 1 1
UUID=c0686... /home btrfs subvol=home,x-systemd.device-timeout=0 1 1
...
/ is initially mounted readonly by the initramfs, and then after switching
to the real system, /home is attempted to be mounted in parallel with /
being remounted rw. If remounting rw happens first, boot proceeds. If
mounting /home is attempted to realy, it fails.
$ /bin/mount /home
mount: /dev/mapper/luks-765... is already mounted or /home busy
/dev/mapper/luks-765... is already mounted on /
$ /bin/mount -o remount,rw /
$ /bin/mount /home
$
So, is this expected that the other subvolume must be mounted rw?
