Thanks > I just attempted debugfs, which is freshly downloaded from e2fsprogs.sourceforge.net website (it has enhanced support for Ext4). I suspect the answer to your question is "time delay" (not sure correct or not, but Ext4 offer This are my results: /download/e2fsprogs/e2fsprogs/debugfs>./debugfs debugfs 1.40.8 (13-Mar-2008) debugfs: open /dev/sdb2 debugfs: lsdel Inode Owner Mode Size Blocks Time deleted 6146 0 100644 0 1019/ 1025 Sat Mar 29 14:41:14 2008 6164 0 100644 0 174/ 1025 Sat Mar 29 14:41:16 2008 6165 0 100644 0 182/ 1025 Sat Mar 29 14:41:16 2008 3 deleted inodes found. debugfs: lsdel Inode Owner Mode Size Blocks Time deleted 6164 0 100644 0 174/ 1025 Sat Mar 29 14:41:16 2008 6165 0 100644 0 182/ 1025 Sat Mar 29 14:41:16 2008 2 deleted inodes found. debugfs: lsdel Inode Owner Mode Size Blocks Time deleted 6164 0 100644 0 174/ 1025 Sat Mar 29 14:41:16 2008 6165 0 100644 0 182/ 1025 Sat Mar 29 14:41:16 2008 2 deleted inodes found. debugfs: lsdel Inode Owner Mode Size Blocks Time deleted 0 deleted inodes found. While on another terminal I will delete the files using "rm xxxx" for files on the mounted filesystem. So the answer is that the kernel takes some time - not instantly (which I suspect is a feature of Ext4?) before it display zero inodes in the debugfs output. BTW (not sure if related or not), the string "testfs" you entered above, may have to be corrected to "test_fs", as that is specifically the string that mke2fs.c check for (search the e2fsprogs/misc subdirectory). -- Regards, Peter Teoh -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
