 Posted: Fri Jun 18, 2010 1:37 am Post subject: udev wont create sda* nodes [SOLVED] |
 |
|
I just changed the motherboard on my system. I booted to a gentoo install cd, chrooted to my root partition and recompiled my kernel with the driver for my new motherboard's sata dirvers. I then successfully booted from my root partition but I cannot mount any other partitions because there are no udev nodes for any of my partitions in /dev.
| Code: |
ls /dev/s* -d
/dev/sg0 /dev/sg1 /dev/shm /dev/stderr /dev/stdin /dev/stdout
|
I don't really understand udev and I thought that nodes like this should be automagically created by udev. Is there a setting I need to change in udev or did I make a mistake configuring my kernel?
| Code: |
dmesg | grep sd
Command line: root=/dev/sda5
Kernel command line: root=/dev/sda5
sd 2:0:0:0: [sda] 2930277168 512-byte logical blocks: (1.50 TB/1.36 TiB)
sd 2:0:0:0: [sda] Write Protect is off
sd 2:0:0:0: [sda] Mode Sense: 00 3a 00 00
sd 2:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
sda:
sd 2:0:0:0: Attached scsi generic sg0 type 0
sda1 sda2 sda3 < sda5 sda6 sda7 >
sd 2:0:0:0: [sda] Attached SCSI disk
EXT3-fs (sda5): mounted filesystem with writeback data mode
EXT3-fs (sda5): using internal journal

| Generally, nodes for supported hard drives should appear. A kernel configuration problem should have prevented you from mounting root, but root appears to be mounted. What is the output of emerge --pretend --verbose sys-fs/udev; emerge --info ; find /etc/udev/rules.d -type f -print | while read f; do echo $f; nl $f; echo; done; find /dev -type b -ls? |

| Do you have TMPFS enabled in your kernel? |

| Thanks krinn. The problem was that CONFIG_SYSFS_DEPRECATED_V2 was on. |
