[Tfug] Filesystem suggestion

[erich]

      I have a jfs system under LVM. That is the partition is 
expandable  over
one or more hard drives.

       Why jfs? Well, because I want proficiency at handling large 
files. Copying,
deleting, or moving, (which amounts to doing both), can be time consuming
for large file sizes (>= 5G)

       Why LVM?  Because it is possible to add other drives as your library
expands. There is a caveat here: If the partition is resized, a reformat 
operation
is inevitable. Provision must be made to copy off the contents of the old
partition, and restore these contents  on the new.

        My system  has had several, (inadvertent), crashes, and jfs came 
thru
with flying colors. I was still nervous about the userland since that is 
still
an ext3 filesystem.
