If you do, then you could see which blocks belong to the file and calculate the block based on the above offset and the filesystem block size.

VFAT i_pos value
I'm getting this error: FAT: Filesystem error (dev sblsnap0) fat_get_cluster: invalid cluster chain (i_pos 523791) I'm wondering if there was a way to figure out what sector is causing the error? I would like to try and track down what is changing that sector and fix the problem. Is there a straight forward way to convert i_pos to a sector value? I've been staring at the fat.c and fat.h code all morning, and I'm having trouble grok'ing the flow. -Kai Meyer ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Then just pass the command line option to sleep for a while before looking for the root device. I do that just fine on my tiny dns server that runs from a USB flash drive. Look in Documentation/kernel-parameters.txt for the rootdelay= option for more details as to what to do.

Booting root filesystem from usb device
Hi, I have a very silly question. I was building a small hand made root filesystem (with busybox and such) just to show how the process would be done. Something pretty similar to free-electrons 'embedded linux from scratch' (http://free-electrons.com/docs/elfs/) but on a usb device (pen-drive). So, I put me kernel, busybox and stuff and installed lilo onto the mbr. The problem is when the kernels boots it can't find the usb partition (sdc1) to mount (i.e. the root device). I know the usual way to do this is using initrd or similar, but I don't want to get that into the equation since the whole project is just for educational purposes and I want to keep things as simple as possible.
