We have been trying to use e2scan to generate a list of files that were changed since a specific date. We are seeing that it has been missing some of the modified files and was wondering if anyone else has seen this behavior.
I executed: e2scan -N "Mar 27 08:00:00 2009" /dev/mapper/mdt_scratch > chad.out [r...@abe-mds04 projects_sync]# grep ILRocstar chad.out ./ROOT/.projects/roc/fnajjar/ILRocstar [r...@abe-mds04 projects_sync]# The following list is a very small subset of files within this directory that were changed after the scan date: [r...@abe-bk1 ILRocstar]# pwd /cfs/scratch/.projects/roc/fnajjar/ILRocstar [r...@abe-bk1 ILRocstar]# ls -lR | grep "Mar 28" drwxr-x--- 4 fnajjar gac 4096 Mar 28 00:56 RSRM105_3D_HG drwxr-x--- 2 fnajjar gac 4096 Mar 28 00:56 Turb_LES -rw------- 1 fnajjar gac 4424 Mar 28 01:05 IVHG_j01.o863001 -rw------- 1 fnajjar gac 4412 Mar 28 02:00 IVHG_j02.o863005 -rw------- 1 fnajjar gac 4427 Mar 28 05:53 IVHG_j03.o863017 -rw------- 1 fnajjar gac 5616 Mar 28 06:54 IVHG_j04.o863026 -rw------- 1 fnajjar gac 5084 Mar 28 11:47 IVHG_j05.o863591 -rw------- 1 fnajjar gac 4489 Mar 28 11:58 IVHG_j06.o863592 -rw------- 1 fnajjar gac 4428 Mar 28 20:55 IVHG_j07.o863637 [r...@abe-bk1 ILRocstar]# ls -lR | grep "Mar 28" | wc -l 164 [r...@abe-bk1 ILRocstar]# We are wanting to use e2scan to generate a list of files to back up with tivoli, because it is much faster to pass tivoli a list than have it traverse the entire tree. However, it looks like e2scan can't be trusted to generate a valid list. The version of e2scan we are running is: [r...@abe-mds04 projects_sync]# rpm -qilf `which e2scan` Name : e2fsprogs Relocations: (not relocatable) Version : 1.40.11.sun1 Vendor: (none) Release : 0redhat Build Date: Thu 10 Jul 2008 11:21:23 AM CDT Install Date: Sat 20 Dec 2008 04:07:31 AM CST Build Host: lts-build-x86-64-0.co.cfs Group : System Environment/Base Source RPM: e2fsprogs-1.40.11.sun1-0redhat.src.rpm Size : 2085263 License: GPLv2 Signature : (none) URL : ftp://ftp.lustre.org/pub/lustre/other/e2fsprogs/ Summary : Utilities for managing the second and third extended (ext2/ext3) filesystems Description : Any thoughts or suggestions would be greately appreciated.
