Hi,

What is the maximum partition size for SFS/00 partitions?

With partitions under 80GB everything works fine, but with very big partitions all time I receive the "Disk full" message when I try to format.

With FFS larger partitions over 80GB works fine... but are too slow.......

I'm using one Sam440ep-Flex & OS 4.1 Update 2 with two HDD's 500GB each. But I don't want to have a lot of partitions... Any idea?

Thanks in advance

Partition Limits:
- FFS2: 2,2 TB if the blocksize is 512 bytes, more if you use a higher blocksize.
- SFS/00: 128 GB -> blocksize = 512
- SFS/02: 1 TB -> blocksize = 512
- JXFS: only joerg knows, but it should play in same class as SFS/02

- Don't use blocksize more than 512 with SFS/00 or SFS/02

- There are no repair/optimize or other tools for SFS/02 and JXFS.

NOTE: Correct me if mistakes because It's differnets informations collected and I'm not the best expert for this domain .

I have a 450GB partition working fine using SFS/02. SFS/00 is more limited about the sizes it can handle.

Hi,

Mrodfr & ChrisH, thanks for the info.

Finally I partitioned my system under SFS/00 with one big SWAP partition at the beginning of the second HDD. Big partitions are 127.3GB each and 512Kb/Block.

Another question, sorry.. The default next values are correct? Maybe I need to change something?

Buffers = 600
Blocksize = 512
Mask = 7FFFFFF
MaxTransfer = FFFFFFE

Thanks again

Why not? I'm using SFS/02 partitions with bigger block sizes since three years in daily usage without any problems. It was - btw - the default setting of my system builder (SAM440ep).

Only use 512 bytes. Anything else is not supported. When the author of the file system who wrote the code tells you not to use anything but 512 byte blocks you do it.

Just to add a teeny weeny remark on this one...

If one uses MediaToolBox to create and handle partitions with whatever FS it DEFAULTS to a block size of 1024...
Not that i want to blame MediaToolBox for choosing the wrong block size, but if FFS (not sure), JXFS and SFS RELIES on being used with a block size of 512 wouldn't it be possible to tell MediaToolBox to change it to a default of 512 as soon as those SF's are used?

Would that be doable?
I just checked and i have all my partitions set to 1024 because back when i created them i did not read the manual on SFS/JXFS (I need to set them to 512 when i do a backup)

I'm just saying that a beginner will most likely catch that trap aswell

I checked my partitions, and i am catched as well just because of default values It was logical to think, that default values are "100% working and best ones"

Sorry, but this is *not* what the documentation of SFS says. It is true that it *recommends" using 512 bytes/block for best performance, but - in contrast to "not use" - it clearly says that SFS supports block sizes from 512 to 32768.

EDIT: I just checked and it seems that it is easy to catch the value of1024 bytes/block 'cos of default settings in PartitionWizard...

512 is recommended for a reason. Feel free to ignore me but I'll listen to the guy who wrote the code.
