You have listed most of the options available. ANother option is to use
Veritas volume manager, but this will involve cost. Dissuite is the best
option.

Using disksuite to stripe 2 partitions is your
best solution, it will give larger partition and
improve performance.

"We have a Sun Enterprise 450 Server, with Solaris 8,
"with 4 disks of 16 Gbytes each one.
"
"But now, users need more space than 16gbytes. We require
"unique path to users disk.
"
"Which are my options and which is the best
"on performance ?
"
"- Use Disksuite to concatenate 2 partitions
does give you all the space in one pool.
"- Use disksuite to stripping 2 partitions
this should give you the best performance, especially if you can put
the disks on separate controllers. but even if they aren't, -most-
disk i/o transactions are small - pg faults, plus possible read-ahead
- and a matched stripe size will keep activity spread across the disks
no matter how localized it is in the fs, while still needing only one
head seek per i/o most of the time.
i don't know the optimum stripe, but that should be buried -somewhere-
in the disksuite docs.
"- Use links at user level to link single user directories
"to another partition
problem here is: what if one user needs 20G?
"- other solutions?
"
"Thanks in advanced,
Andrew Hay
