(and other filesystems) From: crandall@dmacc.cc.ia.us (Charles F. Randall) Date: 1995/10/27 [Yes, this really is a FreeBSD question, read on...] SGI's IRIX 5.3 (with ONC3/NFS) includes a Cache File System (CacheFS) described as "a new file system type ... that provides client-side caching for NFS and other file system types." >From the manual... "CacheFS is optimally used on an NFS client that has sufficient local disk space to reduce network data access time. Once the data has been cached, file read and read-only directory operations are as fast as those on a local disk. Write performance, however, is closer to an NFS write operation." In essence, you create a fixed-size "cache file" on a local disk and then point cachefs at the filesystem you wish to cache (most likely NFS and/or CDROM). Are there any plans in FreeBSD for anything like this? -Randy -- Charles F.

If you have a slow network, you buy a faster network, if your cdrom is slow, you buy a faster cdrom, not more disk space. In my opinion this is not cost-effective because you cannot get definite performance impact.

Consider the situation where the NFS server and client (with a small local disk) are connected by a slow network link which you do not own. An extreme example, but it should illustrate my point. The client-side caching in AFS should serve another implemented example. -Randy -- Charles F.

It remains up to the implementation how useful it would be, for example could it be used as a generic nfs-cache for other non-caching clients so that I could run my dos-pc with pc/tcp off the freebsd caching for a server over the slow (256k) link.

If you can get the cdrom to mount, you should be able to use the X11 port: /usr/ports/audio/xcdplayer. I have been pulling out my hair on My problem with getting four CDROM's to work on one Sony CDROM card. I have sent mail to this newsgroup several times --yet no-one has answered me with an answer. I did however get one hint which got me a little closer. Recompiling the kernel with more scd device entries. This didn't work. Can anyone help me with this problem.

Hmmm, I have atapi configured in the kernel and also did a MAKEDEV wcd0 but somehow the system still doesn't see the CD-ROM.. It seems to see it on the SCSI machine for the SCSI version of the same CD Rom drive. Can someone help me with the problem on the SONY 4x quad speed EIDE drive?
