Description Austin S. Hemmelgarn 2014-01-30 01:45:58 UTC

Upstream btrfs-progs has deprecated and removed the btrfsctl command and replaced it with tha multicall 'btrfs' binary.  For genkernel's initrds to work with multi-device btrfs filesystems, the following line needs to be added to the setup_btrfsctl function in /usr/share/genkernel/default/initrd.scripts:

[ -x /sbin/btrfs ] && /sbin/btrfs device scan

correct btrfs program name

Same problem.  I've got a system with a RAID 1 btrfs root partition.  Using the attached patch & its working fine.

Comment 2 Christopher Head 2014-08-09 06:24:06 UTC

Using a lot of rootflags=device= goop works, but it would be nice to do this the proper way with btrfs device scan.

Comment 3 Austin S. Hemmelgarn 2015-07-20 18:54:19 UTC

Just for reference to anyone who may be interested, I've switched to sys-kernel/genkernel-next as that does actually handle current btrfs-progs correctly (although you need to add BTRFS=1 to /etc/genkernel.conf for it to actually include btrfs support in the generated initramfs).

This should be fixed in HEAD. The fix will be in v3.4.53. I am leaving this open until v3.4.53 is tagged to make it easier to track it.
