Maximum number of subdirectories

Maximum number of subdirectories

[-- Attachment #1: Type: text/plain, Size: 403 bytes --]

Hello,
 
Am a newbie to ReisferFS / Reiser4. 
 
I've been searching the archives and Google for a definite answer as to
what the maximum number of subdirectories under a directory is. A Dec,
2003 article ( http://everything2.com/index.pl?node_id=510028 ) says
it's 64,536. Is this still true ?
 
If not, then what is the current limit for both ReiserFS and Reiser4 ?
 
Regards,
Danny

Hi Vladimir,

By current limit, are you pertaining to ReiserFS (v3.x) or Reiser4 ?

Hi All,

It is pertaining to Reiser4 

On Reiser4 the limit is 2^32 where as on ReiserFS (v3.x) the limit is
64,536 ( not sure)

both in-core inode of linux and reiser4 default disk format store number
of file links in 32 bits.

I guess you mean reiserfs 3.6 and reiser4, or does it also apply to 
reiserfs 3.5?

this also applies to 3.5. But for 3.5 number of directory links does not
get reported correctly: 1 is reported for directories which have more
than 64535 subdirectories.
