- Hello Sun fans:
-
- I am having a small glitch in my disk repartition, and hopefully someone
- else out there knows what really is going on.
-
- I plan on using Mentor Graphics and must change the swap to 150MBytes.
- So, I used dump to save my three partitions:
-
- /, /usr, and /home
-
- Then, I booted off CDROM and then miniroot so that I didn't have problems
- unmounting the local disk. After running format (and then selecting
- the "partition" section, I changed the disk partitions on "g" and "h".
- The idea was, since I mounted another disk for user files (/home/users)
- that I was going to steal all my space from /home. This was not the
- case:
-
- See here my entries in format.dat:
-
- partition = "SUN0424_PREINSTALL" \
- : disk = "SUN0424" : ctlr = SCSI \
- : a = 0, 33120 : b = 46, 65520 : c = 0, 828720 : g = 137, 288000 \
- : h = 537, 442080
-
- partition = "SUN0424_VLSI" \
- : disk = "SUN0424" : ctlr = SCSI \
- : a = 0, 33120 : b = 46, 300240 : c = 0, 828720 : g = 463, 288000 \
- : h = 863, 207360
-
- The VLSI entry was the one I made. As you can see, I tried to maintain
- the size of /usr. I don't know how intelligent format is in the case
- of a mistake when you specify the incorrect starting cylinder.
-
- After running newfs on the g and h partitions, I noticed that I lost 20Megs
- off of /usr! I didn't understand how this could be. It is possible that
- I made a mistake. Here's the entries from two different machines:
-
- The original looked something like (arrows are my notes):
-
- Filesystem kbytes used avail capacity Mounted on
- /dev/sd0a 15487 3242 10697 23% /
- /dev/sd0g 155015 107366 32148 77% /usr <- note
- /dev/sd0h 187463 33857 134860 20% /home
-
- And now it looks like (dings denote problems):
-
- Filesystem kbytes used avail capacity Mounted on
- /dev/sd0a 15487 3062 10877 22% /
- /dev/sd0g 135183 106774 14891 88% /usr <- ding! ding!
- /dev/sd0h 97327 89 87506 0% /home
-
- I am troubled. Please let me know if there's anything that I might be
- doing wrong.
-
- Thanks.
