Defragmenting a NAS...

[jonnyg]

Hello.

Does this post belong in networking or hard drives? Probably both...

Main question:

Does anyone have knowledge of - or a program that will - defragment data on a NAS, in DATAPLOW_ZFS filesystem.

Secondary question:

Does DATAPLOW_ZFS actually need to be defragged?

Thanks,
John

Ok, i found why, just thought i'd post up in case anyone else ever has the problem (also pretty cool facts in here as well):

"What's not normal, however, is the drive format, which Windows reports as SFSZ. So when I tried to run the Windows Disk check and defrag utilities on the [Netgear SC101] drive, Windows politely declined. My contact at Zetera explained that SFSZ is a enterprise-class SAN file system from DataPlow designed for "very high-end applications and supercomputing centers". He said that since the file system is self-correcting, there is no requirement for a disk check and repair utility. He also said that defragging isn't necessary because blocks are directly written to disk rather than files, which need to be arranged for good read performance."

Cool, huh. If you find filesystems interesting....
