- I have this little problem. I've got two disks on my Sun IPC, an old
- Wren (about 900 MB) and a new Elite (1.3 GB). I had things set up such
- that everything (OS, home partition, var, usr, and swap) was on the
- Elite, and the Wren was just one big empty partition used for data
- storage. But recently one of the gurus here suggested that I move the
- OS onto the wren, and keep the data and home partitions on the Elite,
- since the elite is faster. So I tried to repartition and newfs the
- wren, and had a problem when I newfs'd the last partition (whihc is
- just leftover space I'll use as a data overflow). Here's an extract
- from the script file I was running at the time:

- Taking a look at that partiton in the format table again:
- partition h - starting cyl 868, # blocks 2021370 (1898/0/0)
- So it looks like there's a problem with the second to last block!
- Anyone know what this is about?
-
- Also I forgot to umount this drive (all mounted under the c partiton
- to /data. I already backed it up, so I don't care what happens to the
- contents, but is this bad to do for some other reason?
-
- Finally, should I put my swap space on the faster drive too? I can
- have my swap partition on a different drive from my boot partition if
- I modify the kernal, right?
