While using UML (RAID, etc) I hit current limit of max 8 ubd devices.
Looks like this number is hardcoded as MAX_DEV in arch/um/drivers/ubd_kern.c
There is an article in this list by James McMechan, sent 1.5 years ago,
stating that it is possible to adjust MAX_DEV to, say, 16, but it wont
be possible to use /dev/ubd/10 and further.
What is the state of this by now:
Is it safe to adjust hardcoded MAX_DEV to 16?
Does somebody use this in production?
I use 2.4.26 kernel, skas patch for host, 2.4.24-1 patch for UML.
