Re: Panic while creating UFS fs on vn(4) for initrd
Hrm. I don't think you can create an 8 TB UFS1 filesystem. The
limitation for UFS is 2TB, and even that might be a bit dangerous
because ufs uses 32 bit filesystem block numbers. Theoretically
it is based on the UFS frag which is usually 1K or 2K, and negative
block numbers are used to index meta-data, so (2^31) * 1K = 2TB.
I don't quite know why it crashed... the VCHR is missing its cdev
pointer (it is NULL for some reason), but it could be related to the
size of the backing store you tried to create the UFS filesystem with.
