Message-ID: <CAEUQcegWM0d3tmpNXVmeOSKAJUPzthk8uH96XMN+Ax_5ex5H5Q@mail.gmail.com> Date: Sun, 24 Mar 2013 22:05:12 +0530 From: Subranshu Patel <spatel.ml@...il.com> To: linux-ext4@...r.kernel.org Subject: Type of filesystem block Query related to finding the block usage information of metadata blocks in ext4 filesystem. Using debugfs testb command I can check whether a particular filesystem block is used or not. # debugfs -R "testb 171428" /dev/sdd4 debugfs 1.41.12 (17-May-2010) Block 171428 marked in use Also its icheck command prints the inode associated, if any, with a filesystem block. # debugfs -R "icheck 171428" /dev/sdd4 debugfs 1.41.12 (17-May-2010) Block Inode number 171428 65152 But I don’t find any debugfs command which can show similar block usage information about metadata blocks, whether it is a superblock, or inode bitmap block or block group descriptor, etc. Is there any way to extract the usage information of metadata blocks in ext4 filesystem ? -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
