hi all!

after the recent update of udev to 197-r4 i cannot mount my usb harddrive even though it was recognized by kernel:

Code:

usb 1-4: new high-speed USB device number 22 using ehci_hcd
scsi3 : usb-storage 1-4:1.0
scsi 3:0:0:0: Direct-Access     Maxtor   3200             0344 PQ: 0 ANSI: 4
sd 3:0:0:0: Attached scsi generic sg1 type 0
sd 3:0:0:0: [sdb] 625142448 512-byte logical blocks: (320 GB/298 GiB)
sd 3:0:0:0: [sdb] Write Protect is off
sd 3:0:0:0: [sdb] Mode Sense: 17 00 00 00
sd 3:0:0:0: [sdb] No Caching mode page present
sd 3:0:0:0: [sdb] Assuming drive cache: write through
sd 3:0:0:0: [sdb] No Caching mode page present
sd 3:0:0:0: [sdb] Assuming drive cache: write through
 sdb: sdb1
sd 3:0:0:0: [sdb] No Caching mode page present
sd 3:0:0:0: [sdb] Assuming drive cache: write through
sd 3:0:0:0: [sdb] Attached SCSI disk


but there is no /dev/sdb1 to access :(
i must add that i did not reboot after the update to 197 but only restart udev through /etc/init.d/udev restart
is there a way to add the device without rebooting?

thx in advance

snIP3r,

Did you miss the message about updating your kernel with DEVTMPFS support?
You must do that before you reboot, or you will need a liveCD to pick up the pieces.

If you really really don't want to reboot, you may be able to use mknod to make the /dev entries you need.

hi NeddySeagoon!

yes, i prepared my kernel(s) with the devtmpfs option - cause i read the message via elogv after upgrading to 197 ;)
but nevertheless i did not want to reboot so i'll first try your mknod suggestion.

thx for help!

EDIT: for all having the same problem like me: i solved it in my case while typing
Code:

mknod -m 0660 /dev/sdb1 b 8 17
