kernel panic-not syncing: VFS: unable to mount root fs on unknown block(1,0)

AlexPDX

Hello…im geting this error with FOG 1.5.6
im using IBM Blade Server with virtualisation…all of the other machines seam to work fine with no problems

george1421

Hmm… I find it interesting that its trying to load a non-fog init (virtual hard drive). Why is it referencing fog/images/init.gz Secondly, the init for fog should be .xz compressed and not .gz compressed. Off the top of my head, I don’t know of the FOG kernel will be able to expand a .gz compressed file since natively it only understand .xz.

But the error basically says the kernel could not connect to the virtual hard drive.

AlexPDX

It’s done …I have completely installed the virtual machine but also the fog server with the latest version, at the moment it seems that everything works just fine, I managed to capture the image of windows 10 with MBR, also did a full inventory of the work station , i deployed it on another workstation … momentarily I’m with kernel 4.19.36 … I’m thinking to update it at 4.19.48 … but I doubt it will not come up with the same problem … however i will try anyway
10x for the help ! …specialy @george1421 but also @Tom-Elliott ( apparently the problem started from the location where my images are saved…bad cfg )

@AlexPDX OK, can you show me the host definition for the system Windows10-CLEAN?

Also I have to ask you why you have this item in the FOG iPXE menu?

item FOG_1.5.5 FOG Server

kernel bzImage loglevel=4 initrd=init_32.xz root=/dev/ram0 rw ramdisk_size=127000 web=http://192.168.192.111/fog/ consoleblank=0 rootfstype=ext4 storage=192.168.192.111:/images/ storageip=192.168.192.111 loglevel=4
imgfetch init.xz
boot || goto MENU

This is set as default but it doesn’t “do” anything. I know it boots the fog kernel, but its not a standard menu item.

Back to what you posted there is nothing in the iPXE menu to call fog/images/init.gz that I can see.

Lets start with the host definition screen shot, then if that doesn’t give us a clue, I’ll have you schedule a capture or deploy (whatever you were doing to that computer when it threw that error), but don’t pxe boot the target computer. I’ll want you to run that second link. As long as the computer mac address is the same it should give us a little better picture. When a task is running, that call to boot.php will be very short.

@AlexPDX said in kernel panic-not syncing: VFS: unable to mount root fs on unknown block(1,0):

I followed the instalation steps exactly

I find this hard to understand. If you followed the installation steps exactly then it would not try to load fog/image/init.gz. Where did you get the instructions to install fog 1.5.6?

Can you go to this url with a web browser and then post the output here. http://192.168.192.111/fog/service/ipxe/boot.php?mac=00:00:00:00:00:00 and also http://192.168.192.111/fog/service/ipxe/boot.php?mac=f8:b1:56:d9:b8:ab

AlexPDX

I did not expose myself correctly … my bad : ) … I use the IBM Blate server for virtual machines … each one has its own separate work … and I have taken resources from the server to create a Fog Server. I followed the instalation steps exactly … and this error occurred while trying to capture a workstation with windows 10 MBR

Tom Elliott

It can open .gz, but you’re right. By default, we use XZ compression for the init’s.

Even more odd is the fog/images/init.gz being the configuration path from the old 0.32 versions (and earlier) when it referenced the init from /tftpboot/fog/images/init.gz

Did you follow configuration from a very old tutorial?
