The DFS (Distributed File Service) project (under development) will
provide a virtual block interface (eg READ/WRITEVBLK) to applications.
A virtual block is a particular block of a known file.
Naturally, the most prominent "application" will be RMS.
We're interested in learning about any applications out there which
decide to go after disk blocks using LOGICAL IO (eg READ/WRITELBLK).
A logical block is a particular block of a known VOLUME. Such
applications would be incompatible with DFS.
Feel free to reply here, or send me mail with your information.

Yes, I'm stupid enough to have written a number of programs that do logical i/o. Some of these are disk recovery programs for recovering data off crashed VAX or PDP-11 disks. Others are to read foreign disk formats e.g. see my CPMFLOPPY program in the Toolshed. Doug. | |||||
| 310.2 | WHY DO IT LOGICALLY ??? | TROPPO::RICKARD | Doug Rickard - waterfall minder. | Wed Oct 08 1986 00:24 | 10 |
Just remembered, my VAX/XXDP program also uses logical i/o. It allows one to mount a PDP-11 diagnostic pack ( which is in modified DOS V2 format (remember that ???)) on a VAX and down line load the diagnostics to PDP-11s hanging off serial terminal lines. Doug. | |||||
