Re: [Veritas-bu] Open Q to the List: What is the "Best" Filesystem for a staging disk

I haven't tested ZFS yet.
The problem is that after a while the performance on UFS goes dramatically down due to fragmentation. VxFS performs better as it handles better the fragmentation.

I've done only tests using disk staging with JBOD and SAN attached disks.
UFS performed pretty well. VxFS was a bit slow on clearing image files, but that wasn't a huge problem as the image cleanup didn't always happen when I was trying to
write new ones. Since it was VxFS, I could manage it using our standard tool set and I knew it would most likely survive a host crash and not corrupt itself. ZFS had a lot of overhead that my test system didn't appreciate, but did ok.
If I had a faster system, performance might be a non-issue, and the reasons for picking one would be for the feature set.
