Hi, in my previous mail, ls -li ** give all the files in the filesystem (directory capture has inode 12 and cut 13). In cp15730 and cp15731, there's only one file with inode 14. Heres's the 3 stat outputs : philippe@micro11:~$ sudo mount -t nilfs2 -r -o cp=15730 /dev/mapper/vg11a-video mnt/snap5 philippe@micro11:~$ sudo mount -t nilfs2 -r -o cp=15731 /dev/mapper/vg11a-video mnt/snap6 philippe@micro11:~$ sudo mount -t nilfs2 -r -o cp=15732 /dev/mapper/vg11a-video mnt/snap7 philippe@micro11:~$ stat mnt/snap5/cut/f5_20110125_202053.ts\(0\).Xcl File: « mnt/snap5/cut/f5_20110125_202053.ts(0).Xcl » Size: 47 Blocks: 8 IO Block: 4096 fichier Device: fe00h/65024d Inode: 14 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/philippe) Gid: ( 1000/ UNKNOWN) Access: 2011-01-25 22:33:34.914556435 +0100 Modify: 2011-01-25 22:33:34.914556435 +0100 Change: 2011-01-25 22:33:34.914556435 +0100 Birth: - philippe@micro11:~$ stat mnt/snap6/cut/f5_20110125_202053.ts\(0\).Xcl File: « mnt/snap6/cut/f5_20110125_202053.ts(0).Xcl » Size: 6214528000 Blocks: 18446744073697366064 IO Block: 4096 fichier Device: fe00h/65024d Inode: 14 Links: 0 Access: (0644/-rw-r--r--) Uid: ( 1000/philippe) Gid: ( 100/ users) Access: 2011-01-24 01:30:02.260271565 +0100 Modify: 2011-01-24 01:30:02.260271565 +0100 Change: 2011-01-25 20:28:48.894851740 +0100 Birth: - File: « mnt/snap7/cut/f5_20110125_202053.ts(0).Xcl » Size: 0 Blocks: 0 IO Block: 4096 fichier vide Device: fe00h/65024d Inode: 14 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/philippe) Gid: ( 100/ users) Access: 2011-01-29 18:19:51.719138031 +0100 Modify: 2011-01-29 18:19:51.719138031 +0100 Change: 2011-01-29 18:19:51.719138031 +0100 Birth: - PhC -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
