Anyone working on PFS3 ??

[MickJT]

From what i've read, the source code that was released is for version 18.3.

There was an important bugfix in 18.5 that is needed for Apache to work. Is that fix existing in the source code at sourceforge.net?

It may be a "Fact" to Piru and yourself but I beg to differ I say SFS is fast and again it's all down to opinions, nothing else...

SFS stops being fast when admin blocks are cluttered over the disk. Performance degrades faster if you are using .recycled directory but reality is that newly formatted SFS disk is always faster than old empty SFS disk.

[itix]

Then more fool you as SFS doesn't have the filesize or HD size limitations that PFS3 does...

SFS partitions are limited to 127GB and filesize can not be larger than 2GB. In theory you can have file size to almost 4GB but it is not guaranteed to work with all applications.

[Damion]

Slow is just your opinion Piru and of course your entitled to that.

I guess it's the opinion of the several Amigas I own, too. In addition to being subjectively faster by an obvious measure, the PFS3 partitions always booted faster by several seconds and won all the filesystem related tests and benchmarks.

This is on everything from A1200 and A4000 internal IDE, to accelerator SCSI on my GVPA530, TekMagic 2060, CS-MK2, CSPPC, and finally USB drives off the DENEB. I also have a vague recollection of PFS3 blowing away SFS on my old Pegasos (but that was a long time ago).

No data loss either since I purchased it sometime in the late 90's, including testing some purposefully flaky setups.

SFS is dog slow compared to PFS3 though. Also there for sure is a limitation of 2TB, so there's no use in getting a HDD larger than that.

And filesystem limitations aside, IIRC 2.5TB drives and above use 4k physical block sizes.  I know this is a problem for some PCs, but I'm not certain about the Amiga.

Sorry mate but your 100% wrong on both claims...

With the introduction in SFS of SF2 partitions the 127GB limitation was done away with a number of years ago along with the 4GB filesize...

With an SF2 partition there is on limit in theory as to the partition size or filesize...

Hence the reason why on my 2 500GB Amiga HDs I have 250Gb partitions crammed full of DVD Dual Layer ISO's of up 8.3GB individual file sizes and all can be read or written on the Amiga without any problems whatsoever and I've been doing this on a daily basis for a number of years now without any problems or loss of data...

I suggest to all who like to make these false claims to download SmartFileSystem themselves and read carefully the docs and better still try it out for themselves before making such incorrect statement and claims here...

I have some vague memories about reading somewhere that some zones of the HD (when sectors are written at the borders) are faster than others -inner ones- (but I may be wrong)

BTW, nothing to argue against PFS3 vs SFS performance, I just hope it jumps to 64bit soon so we can enjoy bigger HDs and >4GB files with it too. I use ext2 due to big files and my partitions are formatted as SFS so I doubt I*switch soon-ish

See http://sourceforge.net/tracker/?func=detail&aid=3285730&group_id=532591&atid=2163218

The filesystem itself should be pretty much in par with 18.5 now, except that it's actually even better (several serious bugs have been fixed).

[Piru]

RDB can only handle 32bit sector numbers. Unless if we ditch RDB for GPT (or similar) we're limited to 2TB disks.

In addition TD_GETGEOMETRY is limited to 32bit sector count:

Code: [Select]

       ULONG dg_TotalSectors;    /* total # of sectors on drive */
There's nothing a filesystem can do about this. And before anyone asks, no, adjusting your block size for the filesystem will not help here.

Franko: You just love to piss off Piru don't you?

Nope... believe it or not I actually think Piru gives out some very useful and helpful advice, just when he's wrong about something he seems to lack the ability to admit it...

And in this case anyone can easily download SmartFileSystem from the link I gave and test it for themselves to see that no matter what Piru says on this subject he is just simply wrong...

[XDelusion]

Franko: I could never get SFS to work. I have heard it is faster and more flexable than FFS, but have never heard anyone but you claim that it was better than PFS, which I am currently using.

On that note, I can say that PFS is NO FASTER than FFS when used with a CF Card via IDE adaptor. My A600 030 still opens directories at the same slow speed at 16 Colors, though I can at least use larger partitions now, so I'm half way happy at least.

Piru: Are there any advantages to me updating my MorphOS partitions to PFS over the default file system that MorphOS uses during an install?

Assuming your HDD uses RDB and it's thus possible to use PFS3...

Yes. Even the 68k PFS3 is a lot faster than SFS.

Later on PFS3 will be included in MorphOS itself, too.

Tell me, how many >2TB hard disks have you partitioned with an amiga?

That's simply because fewer folk have heard of SFS let alone given the last version released (Ver 1.279) a try. I've used PFS myself but it's filesize limitation was my main reason for switching to SFS as I need to be able to read & burn full DVD ISO images (ie bigger than 4GB) on my Amiga's...

Whether I'm the only person to say it's more flexible doesn't matter to me, the point is it works and can do the stuff I require which PFS can't do...

[Franko]

Tell me, how many >2TB hard disks have you partitioned with an amiga?

None... as the biggest drives I use are 1TB...

Now you tell me after you've given SFS Ver 1.279 a try on an Amiga that it has a 2TB limitation...
