2gb clusters?!
As I recall, linux can do 2gb clusters. Is this true? Worth it? Seems like this would kill any fragmentation issues!

If you use clusters that big, I'm going to bet you'll waste a ton of space...

clusters what do mean storage nodes or serial and parallel processing
Now that swap partition limit may still be 2GB Last edited by SHS; 01-04-2006 at 08:08 PM. |

If the cluster size doesn't affect the storage nodes, how's it going ot help with fragmentation? On a windows PC, cluster size directly relates to the smallest size a file can use on disk. A 1k file on a 64k cluster-sized drive takes 64k. While I'm assuming that Linux functions the same (never payed much attention, and I always accepted the default values for all that in Linux).

2gb partition? lol, that's the partition limitation for FAT16
that said, ext2 has a partition size limit of 2TB but a file size limitation of 2GB XFS and JFS can handle the larger files (+4GB files) ... steer clear of ReiserFS3/4 |

You take a performance hit with the Reiser FS's don't you?

Linux has lots of advantages for storage over windows. That said, I strongly hold to the view that large amounts of storage should be in a different computer than the HTPC. HTPC's tend to have issues with noise and ventilation, and adding a lot of disk to that doesn't do the system or the disk any favors. I can testify that you can achieve high levels of performance serving from Linux to windows over GB ethernet. Thanks, Mike |

so anyways...
2gb clusters is just food for thought. I suspect that it would only be useful if you have your recording settings at 2gb/hr. So in my case, I record at 3.2gb/hr, so it may be more beneficial to have .65gb (or so) clusters. Doesnt seem like waste to me. Plus, I would assume that it will be helpful to reduce seek time and generally better on a HD. I. EDIT: meant .65gb

I was going to suggest something along the 64m range myself, or at worst whatever size you're recording settings are / 2, so a half-hour show would fit into one cluster (you'd better pad the numbers just a bit tho, or you'll waste a ton of space if your show goes over by a couple minutes/megs...)
I just hope they offer a upgrade for us so we can convert an existing SageTV key to a Linux Key...
