[Bug 1579739] [NEW] ubuntu 16.04 install fails at grub install on btrfs

[AurelienG]

Public bug reported:

root at ubuntu:/# parted -l
Model: ATA WDC WD5000BPKX-2 (scsi)
Disk /dev/sdb: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt

 3      11.6GB  116GB   105GB   btrfs

root at ubuntu:/# mount
/dev/sdb2 on /yourmom type btrfs (rw,relatime,space_cache,subvolid=5,subvol=/)
/dev/sdb1 on /yourmom/boot type btrfs (rw,relatime,space_cache,subvolid=5,subvol=/)

root at ubuntu:/# grub-install --root-directory=/yourmom /dev/sdb
Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: error: filesystem `btrfs' doesn't support blocklists.


The 1000M partition is for /boot, the 10G for /, the 100G for /home.
I created the partitions using gparted 0.25.0
The release of Ubuntu is 16.04
I expected grub-install to succeed as there is plenty of space before the first partition.

I got the install working by using an msdos table and an unformatted
primary partition instead of free space at the beginning of the disk :
