Has anyone implemented disk quotas in Mach (as in Encore or CMU release), or found a suitable substitute hack? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Peter Fay College Computing Center ~ ~ (fay@wpi.wpi.edu) Worcester Polytechnic Institute ~ ~ (508)831-5725 100 Institute Road ~ ~ Worcester, MA 01609 ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Disk quotas are part of the CMU Mach release since they are part of the BSD file system. Quotas are not part of the Encore release since we didn't expend the effort to parallelize them. It is certainly possible for someone (with our source and with the appropriate amount of experience) to paralleize the quota code, but it won't be a trivial effort. Encore *did* parallelize the quota code for OSF/1, but even if you have that code it won't help you with the Encore Mach release. OSF/1 is based on the 4.4BSD file system while Encore's is based on the 4.3BSD file system. ---- Joseph Boykin Manager, Mach OS Development Encore Computer Corp Treasurer, IEEE Computer Society Internet: boykin@encore.com Phone: 508-460-0500 x2720

Peter, OSF/1 provides fully parallelized disk quotas based on the code developed for the 4.3-Reno distribution. The Encore Mach release does not currently support quotas. Based on the filesystem code in the CMU and mt Xinu releases, I expect that those releases support quotas (the old 4.3BSD style quotas), but I don't know anyone who has tried using them. ----- Alan Langerman (alan@encore.com)
