Everything worked great till I started screwing around with adding block
devices getting ready to transfer everything to a disk partitions; now
block devices--seemingly at random--aren't available on Linux boot. I
haven't been able to figure out any consistent pattern to determine
which block devices will be visible within Linux and which will be
missing, but once a device disappears, it rarely reappears on subsequent
boots. I don't believe that the swap image ever disappeared before I
tried including disk partitions, but now it isn't even visible when I
revert back to my original configuration.
By "not visible" I mean that the device doesn't show up in
/proc/partitions. I've tried uninstalling and re-installing coLinux
itself and the linux.sys driver (rebooting between uninstall and
reinstall). I've tried booting with init=/bin/bash to make sure that the
initscripts weren't messing anything up.
Host OS is Windows Vista, running on a Core2 Duo laptop. I think all the
other information you need can be seen in the output below. Each of the
"missing" block devices has successfully been mounted in coLinux at
least once, but devices do "disappear" even if they've never been used
before--i.e. if I create a new empty file then try to include it as a
block device, it often will not be visible in Linux.
Below is an example of what I'm talking about. Notice that it
successfully maps the devices before the kernel boots, but only cobd0
appears in /proc/partitions. Let me know if there's any further
debugging information I can supply.
Cheers
