On a customer's machine running SuSE 9.2, the size of the occupied space on the harddisk is reported incorrectly by "df -h". After we noticed the problem, I rebooted the machine and had it checked by "e2fsck" (check forced with "tune2fs -C 40", we are not on location). Right after the reboot I proceeded as follows, but I could not find any information about

What happens when rsync'ing a file that is damaged bacause of a bad sector on the source medium? I assume that the file will be synchronized partially, overwriting any file of the same name on the destination medium. If that is the case, is there a way to make rsync check readability of files before overwriting them on the target medium (e.g. by synching to a temp. file and, once

Consider the following scenario: * A database is accessing a large file $a on an Ext3FS, writing to it, reading from it. * While testing a backup script, the file $a is copied with rsync without prior shutdown of the database software. Here's what just happened under this scenario: $a got damaged. I'm certain that this is just a conincidence. However, my employer recalls

Let me preface this by saying "Yes, I know *nix filesystems don't need to worry about fragmentation". That said, is there a way to check the overall level of fragmentation of a live ext3 filesystem? I know about filefrag, but that's for specific files. And I think e2fsck tells you, but only if you take the filesystem offline for the scan. Is there anything that will give

Hi - We have had a raid failure, we have some what recovered but we continue to see the following ext3 message...

Hello everyone, I am a novice with KLEE under LLVM. I am trying to build a KLEE project (on a new LLVM environment) and I have the following problem: echo Testing... Testing... echo There should be no assertion fails! There should be no assertion fails! klee -taint=direct taint_direct.o KLEE: output directory = "klee-out-8" klee: error: Cannot find linker input

Are there any "current" Linux distros that have installable packages for llvm, clang, nad klee? I am struggling to get klee built and need a working klee setup asap. Thanks in advance, Donald

Hi, The klee library directory is determined at compile time and cannot be changed afterwards. Have a look at tools/klee/main.cpp to see how it is computed. I usually use Klee without any install step, right from the build directory. This has never given me the error you see. Hope this helps, Jonas On Wed, Jun 5, 2013 at 5:26 PM, Alexandru Ionut Diaconescu < alexandruionutdiaconescu at

Hi, I'm currently trying to find and fix memory leaks (compiling with ``-fsanitize=address``) in the KLEE tool [1] an having found some leaks and I'm having trouble suppressing them. I'm trying to suppress them using the ``-fsanitize-blacklist=blacklist.txt`` option as documented at [2]. I'm using Clang 3.7 ( Arch Linux package 3.7.0-6). The sort of reported leaks I see are ```

Hi, There wasn't much information regarding fragment support of ext2/3 since 2003 [1], Andreas stating that there were problems with the xattr implementation. Has this changed in the meanwhile? My second question is regarding the bytes-per-inode ratio: What benefits would I gain from having fewer inodes? I reckon it's only diskspace (if so, how much?). best regards, Michael Renner [1]

Hi All, Can anyone help me in resolving this problem. I use Redhat 9 Enterprise edition. I have a session in which I logged in as a root. When I issue the command "su" from any other user it is throwing error "su : Incorrect password", If I try to change the password from the root session, it is throwing error "passwd : module unknown".

Hi, After panic boot, I have executed fsck for the mount point and we couldn't find a single file. We have lot of directories under lost+found like this #3194985. Can anyone tell me how to recover the data from this folder? This is urgent. Thanks in advance for your help.

Hello, In my reading over the last couple of days, I have read that in order for klee to work with "native" Linux programs, I need to install the uClibc posix support for klee. I am not finding the uClibc source in the llvm svn repository anywhere. Is this still necessary for testing native Linux applications, and if so, where do I get the uClibc source to compile? Thanks in

Dear Developers, I am a Master's student at the ECE department of the University of Florida, USA.​​ For my research project, supervised by Prof. Mark Tehranipoor<http://tehranipoor.ece.ufl.edu/> and Prof. Farimah Farahmandi<http://farimah.ece.ufl.edu/>, I need to use Clang LLVM DataflowSanitizer library in KLEE. However, I have faced some difficulties (explained below) while

Hello, probably it is too late to be involved in GSoC, by I want discuss following idea: KLEE can generate tests only for main function level without any modifications of original code. It passes args specified by command line. I want implement automatic testcase generation for any imported function from tested code without its modification. First: parsing test code would collect input/output

Are we likely to see patches to allow 16TB ext3 in the mainstream kernel any time soon? I am working with a storage box that has 16x750GB drives RAID5-ed together to create a potential 10.5TB of potential storage. But because ext3 is limited to 8TB I am forced to split into 2 smaller ext3 filesystems which is really cumbersome for my app. Any ideas anybody?

Folks, I do have a couple of problems I hope you could help to solve. I have searched the net, but had little success of finding documentation about samba 3.2 and AD. I do have Win server 2003 domain and AD in native mode. The new samba server should be a member server in the domain. The idea is to have same UIDs as the RIDs in the AD. The enviroment is as follows. Sernet packaged samba 3.2.3-37

I created a filesystem as follows: mke2fs -j -O dir_index -O sparse_super -T largefile /dev/drbd/6 Here's the the output from df Filesystem Size Used Avail Use% /dev/drbd/6 475G 33M 452G 1% It seems that ext3 has taken 23 GB, which is about 5% of the total disk size, for itself. Is that right? If that is, indeed, the case, why does df just list 33M as being
