Bug : reuse same inode

[Philippe CHATAIGNON <liste-ZXOCcuNttmoBe96aLqz0jA@public.gmane.org>]

Hi all,

I use nilfs2 on a lvm partition for recording dvb streams : it creates
big files and I often deleted them quickly so there only a few files on the partition.

Today I notice a problem : where a new file were created, it takes the same inode that a file already have. 
So the previous file were lost, like if an hard link was made.

philippe@micro11:~$ ls -li $v
total 30051016
14 -rw-r--r-- 1 philippe users    93849600  6 févr. 14:51 f2_20110130_174456.ts
16 -rw-r--r-- 1 philippe users  8606489600  9 janv. 15:42 f3_20110107_205154.ts
14 -rw-r--r-- 1 philippe users    93849600  6 févr. 14:51 f3_20110206_144851.ts
19 -rw-r--r-- 1 philippe users 10623052800  6 févr. 19:55 f3_20110206_145141.ts
15 -rw-r--r-- 1 philippe users  4688870400 19 janv. 23:14 f4_20110119_204007.ts

The file created today is f3_20110206_144851.ts : it reuse inode 14
that the file f2_20110130_174456.ts already had. On the third column, you can see there 
is only one link (and not 2 as if ln was used).

Of course, I can use a snapshot to recover the old file (f2_20110130_174456.ts). 

philippe@micro11:~$ ls mnt/snap2/capture -li
total 32584848
20 -rw-r--r-- 1 philippe users     4812800  5 févr. 17:43 canal_20110205_172318.ts
14 -rw-r--r-- 0 philippe users 13390412800 31 janv. 01:00 f2_20110130_174456.ts 
16 -rw-r--r-- 1 philippe users  8606489600  9 janv. 15:42 f3_20110107_205154.ts 
15 -rw-r--r-- 1 philippe users  4688870400 19 janv. 23:14 f4_20110119_204007.ts

I run Archlinux x86_64 on 2.6.37. It's my first bug report. 
Ask me for additionnal information if I could help.

Regards,

PhC
