Its been long time since I blogged. Now here it comes......................

We never expected we'll finish this fast.
A very basic file system is done. We can now dynamically add disks into the pool.
The removing part is still there. for that we need to defragment the harddisk and so on.... tat job is postponed for next month...

I started with minix_fs. it was one simple filesystem.  I also wrote PFS specific bit operations. [ in pfs_bitops.c].  After going through minix code, some 20 times, i understood all the functions in the itree_common.c.  It was difficult though. Luckily, I needn't change these functions. I copied them as such. We made lot of changes in dir.c... Every thing went like this... Changing was no big problem. Everything got over by 20th of march.


There were some zillion bugs in the file system... There was this bug wat friends called INFINITE FILE SYSTEM. The file syste's size was unlimited... u can fed the disk even with terrabytes of data.. [ofcourse the older the data gets, the more it got corrupted ] Hmm... It took 2 days to fix that bug completely.! 

Anyway.. After all this, The PFS is now bug free.! The dynamic shrinking part is left.! The integation of the file system and the pool is there (not a big job.!). 

We are planning to sourceforge the project soon. We need a perfect documentation etc for this. so this will be done only by next month i guess...

Things tat are left in our project.
* Integration of PFS and POOL.
* Benchmarking.
* Documentation.

Optional modules ( if we have time)
* De fragmenting [ dynamic removal ] .
* Minix - to - PFS porting module.
