Hi I'm trying to activate the swap on my umls. My start commands are ubd0=3Droot_fs ubd1=3Dswap_fs My UML kernel is 2.6.16.9-bs2, downloaded from http://www.user-mode-linux.org/~blaisorblade/binaries/ My system boots normally, I can see the first disk mounted as /dev/ubda. First question, if I do a ls -l /dev/ubd* it doesn't find any devices, how is it working ? To mount the swap area, swapon /dev/ubdb /dev/ubd/1 do not work (device not found), What is the name of the device ? how could I find it ? thanks in advance, Johan |

That's the content of /etc/mtab, please compare=20 with /proc/mounts. > First question, if I do a ls -l /dev/ubd* it doesn't find any devices, > how is it working ? There's a little chance you have still the /dev/ubd/ folder. > To mount the swap area, swapon /dev/ubdb /dev/ubd/1 do not work > (device not found), It's possible that since the kernel mounts the root_fs, it's working anyway. What you likely need to do is to recreate the devices you need like: mknod /dev/ubd0 b 98 0 mknod /dev/ubd1 b 98 16 mknod /dev/ubd2 b 98 32 =2E.. and so on (till ubd7) and/or (depending on your taste) mknod /dev/ubda b 98 0 mknod /dev/ubdb b 98 16 mknod /dev/ubdc b 98 32 =2E.. this can be scripted, but it seems I lost the script, however it's like for ((i=3D0; i < 8; i++)); do mknod /dev/ubd$i b 98 $[16*$i] done the second can be done too (with tr '0-9' 'a-i' to convert $i to the right= =20 letter) but I'm too hurried to do it.
