Just a quick question on when to use VXFS vx UFS with logging.

Currently I have several 1 TB file systems (hardware RAID 5) using VXFS
with 8k extent sizes. One of our file systems has 8 million plus files
of varying sizes. This file system houses user home directories so
there are many small files as well as large files.

Lately, our backups started failing in this file system due to extreme
kernel contention. Veritas claims our kernel parameters and VXFS config
is good to go. I am currently moving this data to another 1TB file
system using UFS with logging but the data is moving at a painfully slow
rate.

Just wanted to get some feedback on UFS with logging, this is the first
I have ever used UFS with logging.

I am running Solaris 8 64-bit on this particular machine. (with latest
patch cluster as of last week)

Thanks for any advice,
Chuck
