It was a wonderful FS, but if you used a PrestoServer NFS accelerator board on the system with 4mb of RAM, but forgot to actually enable the battery, bad things happened when the system crashed... you got a nice 4mb hole in the filesystem which caused wonderfully obtuse panics. All the while the hardware keeps insisting that the battery on the NVRAM board was just fine... turned out to be a hardware bug on the NVRAM board, which screwed us completely.
Once that was solved, back in Oct 93 time frame as I recall, the Advfs filesystem just ran and ran and ran. Too bad DEC/Compaq/HP won't release it nowdays....
