Can you try getting the inode number and then trying to get a pathname to the inode? And then get the on-disk stat information? You can do this using debugfs, for example: debugfs /dev/sda3 debugfs: ncheck 2621442 Inode Pathname 2621442 /u1/Doctor-Who-medley.flac debugfs: stat /u1/Doctor-Who-medley.flac Inode: 2621442 Type: regular Mode: 0644 Flags: 0x80000 Generation: 3942406670 Version: 0x00000000:00000001 User: 18209 Group: 18209 Project: 0 Size: 500591580 File ACL: 0 Directory ACL: 0 Links: 1 Blockcount: 977608 Fragment: Address: 0 Number: 0 Size: 0 ctime: 0x57e99a99:57d3bfbc -- Mon Sep 26 18:00:57 2016 atime: 0x57eef0af:64fe6c84 -- Fri Sep 30 19:09:35 2016 mtime: 0x56b18898:00000000 -- Tue Feb 2 23:56:56 2016 crtime: 0x57e99a95:91002508 -- Mon Sep 26 18:00:53 2016 Size of extra inode fields: 32 Inode checksum: 0xfe12a620 EXTENTS: (ETB0):10543077, (0-2):649216-649218, (18-6143):649234-655359, (6144-16383):7106 56-720895, (16384-24575):696320-704511, (24576-36863):806912-819199, (36864-4505 5):794624-802815, (45056-47103):882688-884735, (47104-71679):892928-917503, (716 80-75775):937984-942079, (75776-77823):1003520-1005567, (77824-83967):1009664-10 15807, (83968-88063):991232-995327, (88064-92159):999424-1003519, (92160-94207): 1021952-1023999, (94208-96255):1028096-1030143, (96256-98303):1040384-1042431, ( 98304-106495):1032192-1040383, (106496-120831):1095680-1110015, (120832-122214): 1085440-1086822 And then can you see if there's any commonality in terms of the workload associated with that inode, or whether or not that inode was likely to be in the process of being modified?
