Doesn't work here. I don't even get a path with the affected kernels.
I'll get:
Label: none uuid: 02edbd6b-f044-4800-b21e-ca8982c2c2e5
Total devices 1 FS bytes used 270.10GiB
*** Some devices missing
Btrfs v3.16
with a working kernel:
Label: none uuid: 02edbd6b-f044-4800-b21e-ca8982c2c2e5
Total devices 1 FS bytes used 270.10GiB
devid 1 size 293.89GiB used 289.06GiB path /dev/sda1
Btrfs v3.16
Filesystem layout is:
subvolid 0 contains only the different subvolumes
ID 257 gen 414674 top level 5 path rootfs
ID 269 gen 414615 top level 5 path home-USER1
ID 317 gen 411498 top level 5 path home-USER2
ID 363 gen 410939 top level 5 path home-USER3
ID 382 gen 315844 top level 5 path home-USER4
ID 933 gen 410514 top level 5 path home-USER5
ID 995 gen 315756 top level 5 path homefs-USER6
subvol rootfs (ID 257) is set to the default subvolume, mounted at
start. Grub commandline is like following:
root=/dev/sda1 ro rootflags=subvol=rootfs,inode_cache,autodefrag
It doesn't matter, if the subvol parameter is set. I've tried with,
without and with subvolid=0 parameter. Everytime the same result.
And now I was able to reproduce on a second machine. The main
difference between the affected and the unaffected systems is
initramfs. On the affected systems, I don't use one. On the working
systems, the rootfs is mounted via initramfs before. I'll test, if an
initramfs will solve the issue. Seems likely, cause if I put the disk
of an affected system into a working system and mount it there,
everything works.
regards,
Johannes
