Sometimes the disk order gets messed up on boot. My first disk (as per |
| 19 |
SATA bus) sometimes gets the letter sdb instead of sda. The solution |
| 20 |
is to use disk labels. Label your file systems (e2label, if you're |
| 21 |
using ext* FS, or xfs_admin for xfs). |
| 22 |
Uncomment DISKLABEL="yes" in genkernel if not already. |
| 23 |
|
| 24 |
And specify disk partitions as root=LABEL=FOO where FOO is the label |
| 25 |
you used for root filesystem. Do not forget to update fstab with the |
| 26 |
same (using labels). |
| 27 |
|
| 28 |
Here's my fstab for a sample and grub.cfg (grub2); posting only relevant lines. |
| 29 |
|
| 30 |
FSTAB- |
| 31 |
LABEL=Gentoo / ext4 |
| 32 |
defaults,noatime,discard 0 1 |
| 33 |
|
| 34 |
grub.cfg- |
| 35 |
linux /boot/kernel-genkernel-x86_64-3.4.4-gentoo-ck2 |
| 36 |
real_root=UUID=90e64854-d65c-4419-a629-4e2ca621a7a0 ro |
| 37 |
real_rootflags=noatime,discard,data=writeback rootfstype=ext4 |
| 38 |
|
| 39 |
Since I use grub2-mkconfig to generate the configuration, it's there |
| 40 |
with UUID, but it works with LABEL as well, I have tried it. |
| 41 |
Also, *don't* build your kernel *without* initramfs, because the |
| 42 |
kernel by default doesn't support mounting by LABELs or UUIDs (I think |
| 43 |
so, I've had failures w/o initrd). |
