Hi to everyone,
I have a student projet quite interessting and
quite hard and the informations found on internet about the ext3 aren't
relevant. That's why I recquire you're help.
My aim is to add some métadatas to my files (like
public,Private, draft ... the list must be extensible) and have the
possibility to display it with the commands line (ls, rm,
...).
There is lots of ways to do that. The more
appropriate is, for me, to implement it directly in the i-node of the Ext3
(more easy in ext2 ?).
Concretly I see it like that (I'm probably
wrong):
The standard i-node contain informations like
Creation/modification dates, rights, number of links ... and I wanted to add a
field string (or some bytes, its the same) where i could put my
metadatas.
Of course the system won't be bootable (and wont be
stable).
Here is a representation :
class|host|device|start_time ils|shirley||1151770485 st_ino|st_alloc|st_uid|st_gid|st_mtime|st_atime|st_ctime|st_mode|st_nlink|st_size|st_block0|st_block11|a|0|0|1151770448|1151770448|1151770448|0|0|0|0|0|MY_FIELD 2|a|0|0|1151770448|1151770448|1151770448|40755|3|1024|201|0|MY_FIELD 3|a|0|0|0|0|0|0|0|0|0|0|MY_FIELD Course, I'm maybe dreaming, it's probably very
hard, but it's interesting to ask to someone more experienced.
Forgive me for my english.
