Environment: / dev/sdb1 is a data partition / data0,EXT3 file system under CentOS 5.3 x86 / 64.

Antecedent: / data0/tcsql/cankao/phpcws-1.5.0/httpcws.cpp file was deleted by mistake. Because I forgot to back up the httpcws.cpp file, the redevelopment workload is heavy, so there is only one way to restore the file.

The debugfs command is fine for EXT2 partitions, but it doesn't help for EXT3 partitions. A piece of open source software that I stumbled upon solved my great favor. The software can be downloaded from:

Http://code.google.com/p/ext3grep/

1. Install the ext3grep software first:

Wget http://ext3grep.googlecode.com/files/ext3grep-0.10.1.tar.gz

Tar zxvf ext3grep-0.10.1.tar.gz

Cd ext3grep-0.10.1

. / configure

Make

Make install

2. Umount / data0 partition:

Umount / data0

If you prompt busy, first kill the process that is using this directory, and then umount:

Fuser-k / data0

Umount / data0

3. Query all Inode (execution takes a few minutes to more than 10 minutes):

Ext3grep / dev/sdb1-ls-inode 2

4. Search Inode step by step to see if you can find the httpcws.cpp file (this step can also be omitted):

5. Restore / data0/tcsql/cankao/phpcws-1.5.0/httpcws.cpp file:

Ext3grep / dev/sdb1-- restore-file tcsql/cankao/ phpcws-1.5.0/httpcws.cpp

"if you are prompted for the following information, the restore is successful:"

Restoring tcsql/cankao/phpcws-1.5.0/httpcws.cpp

At this point, a folder called RESTORED_FILES is automatically generated under the current directory where the ext3grep command is executed, and the tcsql/cankao/phpcws-1.5.0/httpcws.cpp under the folder is the recovered file. Check it out, and it's the same as before it was deleted, and it's done.

6. Re-mount / data0 partition:

Mount / dev/sdb1 / data0
