Background:
System: Netra T1 AC/200 OS: Solaris 8 7/01
No special disk or logical volume management software.
Probably woefully behind on patches.
I wanted to create a UFS filesystem with a block size larger then 8192, but
according to newfs(1M):
-b bsize
The logical block size of the file system in
bytes (either 4096 or 8192). The default is
8192. The sun4u architecture does not support
the 4096 block size.
And when I tried: newfs -Nv -b 16384 /dev/rdsk/c0t1d0s0
I recieved this: newfs: 16384: bad block size
Does anyone know of a relatively simple way of creating a UFS filesystem with
a block size larger than 8192, or if it's even possible?
This system is replacing an old mail server (zmailer) that has become bogged
down with I/O wait. Does anyone have any tips on how to avoid this, ie.
increase disk read/write performance? One of our theories is that the current
mail server is low on RAM (128MB) and stuff is being swapped in and out of
memory so throwing more resources (1GB of RAM) at it might help.
Thanks! Will summarize.
