- We have a HP827 running HP/UX 8.02, using Informix Online 4.0 and
- several 1.3Gb disks, with a default section 5 of approx 900Mb.
-
- A particular application would like to live on a 200Mb partition.
-
- Informix will allow me to configure database chunks specifying a
- raw disk device and an offset, so there shouldn't be a problem
- there. (X-posting to comp.databases.informix in case someone
- knows otherwise)
-
- I would like to configure a unix file system of roughly 200Mb
- on the first part of section 5, and a couple informix database
- chunks on the last part.
-
- I have tested this (in part) by using mkfs to make a "short" system
- at the start of section 5. 'df' reported a file system of the
- desired size.
-
- I spoke to HP support and they assure me that it is NOT possible to
- divide the section in two as the device driver gives you a 900Mb section,
- end of story. ie. "that's the way it works". I was unable to get a
- more technical explanation. When I asked if I could put a short file system
- at the start of the partition, and specify an offset to Informix to build
- a raw database using the rest of the partition, they said that this was
- also not possible.
-
- Is there anyone out there who has succeeded in such an exercise,
- or is able to tell me why it won't work?
