Multidevice f2fs mount after disk rearrangement

Hello.
I was brave enough to create f2fs filesystem spanning through 2 physical
device using this command:
# mkfs.f2fs -t 0 /dev/sdc -c /dev/sdd
It worked fine until I removed /dev/sdb from my system, so f2fs devices
became:
/dev/sdc -> /dev/sdb
/dev/sdd -> /dev/sdc
Now, when I try to mount it, I get the following:
# mount -t f2fs /dev/sdb /mnt/fs
mount: /mnt/fs: mount(2) system call failed: No such file or directory.
In dmesg:
[Jan 4 17:25] F2FS-fs (sdb): Mount Device [ 0]: /dev/sdc,
59063, 0 - 1cd6fff
[ +0,000024] F2FS-fs (sdb): Failed to find devices
fsck also fails with the following assertion:
[ASSERT] (init_sb_info: 908) !strcmp((char *)sb->devs[i].path, (char
*)c.devices[i].path)
Am I doing something obviously stupid, and the device path can be
(somehow) changed so that the mount succeeds, or this is unfixable, and
f2fs relies on persistent device naming?
Please suggest.
Thank you.
