Hi, |
| 16 |
I just had to restart my computer (power issues :( ) in the middle of |
| 17 |
an update (well, it was more like 'just before the end';) and after |
| 18 |
restart I have the same problem as you, no /dev/sd[ab]* files... |
| 19 |
|
| 20 |
My first guess was that I rebooted without updating the config files, so |
| 21 |
I ran etc-update (there were some udev config files as well as init |
| 22 |
script) and rebooted, but that didn't help. |
| 23 |
|
| 24 |
It is certainly not a problem with drivers not being in kernel, as the |
| 25 |
kernel sees the disks and partitions (see below), so I just run |
| 26 |
|
| 27 |
tail -n +3 /proc/partitions | while read maj min size name ; do mknod /dev/$name b $maj $min ; done |
| 28 |
/etc/init.d/localmount pause; /etc/init.d/localmount start |
| 29 |
|
| 30 |
to get everything mounted again... |
| 31 |
|
| 32 |
That means it will have to be an udev (or even openrc) problem. |
| 33 |
The last update of udev did in fact say this: |
| 34 |
|
| 35 |
* Checking for suitable kernel configuration options... |
| 36 |
* CONFIG_SYSFS_DEPRECATED: should not be set. But it is. |
| 37 |
* CONFIG_SYSFS_DEPRECATED_V2: should not be set. But it is. |
| 38 |
* CONFIG_IDE: should not be set. But it is. |
| 39 |
* Please check to make sure these options are set correctly. |
| 40 |
* Failure to do so may cause unexpected problems. |
| 41 |
* |
| 42 |
* udev-151 does not support Linux kernel before version 2.6.25! |
| 43 |
* For a reliable udev, use at least kernel 2.6.27 |
| 44 |
|
| 45 |
* Your kernel version (2.6.28-gentoo-r2) is new enough to run udev-151 reliably. |
| 46 |
|
| 47 |
I didn't want to mess with the kernel right now, but I gues that's the |
| 48 |
first thing to try... |
| 49 |
I'll report when I rebuild & reboot... |

Kernel can see the partitions just fine: |
