 Posted: Fri Sep 02, 2005 6:37 pm Post subject: Where is my sda?? |
 |
|
hi, i have noticed my /dev/sda is gone. well whole sda,sda1,sda2,sda* are gone, in dmesg, when I plug-in usb stick it reconizes as sda, nothing errors.
but i cant mount them because /dev/sda is missing. but sdb is there. so i need to plug another usb stick 1st, let it reconize as sda, then i need to plug my usb so it will reconize as sdb and then i can mount it.
is there anyway making those /dev/sda /dev/sda1 /dev/sda2 etc back? i tried touch /dev/sda but it wasnt e solution.
excuse i cannot most my emerge info because im on different machine and my problem box is offline.
but it was there before, its not anymore, i donno know why.never changed kernel, no errors in dmesg.
thx

So you say that /dev/sda has disappeared? And you only have /dev/sdb to be used for mounting USB block devices?
Try to mknod a new /dev/sda with the same major as /dev/sdb (I remember it should be 180)
If you don't know how to do it, please show me the output of "ls -l /dev/sd*" so then I write the whole command for you to try. |

Hi antiwmac.
You can see the major and minor nodes for /dev/sda* devices from the following
| Code: | atl64 gfxboot # ls -l /dev/sda*
brw-rw---- 1 root disk 8, 0 Ago 21 13:01 /dev/sda
brw-rw---- 1 root disk 8, 1 Ago 21 13:01 /dev/sda1
brw-rw---- 1 root disk 8, 2 Ago 21 13:01 /dev/sda2
brw-rw---- 1 root disk 8, 3 Ago 21 13:01 /dev/sda3
brw-rw---- 1 root disk 8, 4 Ago 21 13:01 /dev/sda4
brw-rw---- 1 root disk 8, 5 Ago 21 13:01 /dev/sda5
brw-rw---- 1 root disk 8, 6 Ago 21 13:01 /dev/sda6
atl64 gfxboot # |
