- Well, whether you can grow an RFS, AFS (assuming that means Andrew File
- System), or NFS file system depends on what the underlying file system
- type is on the server. :-)
-
- With any luck, those internal interfaces to SunOS 5.0 that are exposed
- to file systems are close enough to those of other SVR4 implementations
- - perhaps, in the case of those interfaces that are affected by
- multiprocessor support, close enough to those of SVR4 ES/MP - that the
- Veritas File System for SVR4 (which is apparently the default file
- system in SVR4.2, a/k/a "Destiny") should fit in without too much pain.
-
- VxFS *does* let you grow file systems on the fly, if the partition
- containing the file system can be grown on the fly; Veritas's volume
- manager, for doing "metadisks" (to use the Sun term), allows that.
-
- Sun's DiskSuite unbundled product - or whatever their metadisk product
- is called - might allow growing partitions on the fly; I don't know if
- they've modified the BSD file system to allow growing file systems on
- the fly or not.
-
- I don't know if Transarc'c Episode file system supports it or not (the
- USENIX paper on the DEcorum file system, which talks about Episode,
- which is the on-disk file system part of DEcorum, which I think is now
- called DFS, the distributed file system component of OSF's DCE); the
- paper doesn't say whether it can be done, or at least doesn't say it in
- any obvious place, and I'm too lazy to scan the whole paper right now.
