Hi, I'm using py-rrdtool 0.2.1 with rrdtool 1.3.0 under 7.0-STABLE, and there's a couple of things about this new version of rrdtool that hurt performance under FreeBSD, but apparently help on whatever they tested on. For every update, the database file is opened, mapped into memory, madvise() is called, contents are modified, msync() is called, and the file is unmapped and closed:

Hi people Just switched to Dovecot yesterday, and I've already got about five reports of users with duplicate mail in their inbox :-/. Not as bad as lost email, mind you, but pretty annoying still. Checking the server log, it says: postfix/smtpd: disconnect from unknown deliver: msync() failed with index file maildir/dovecot.index: Input/output error unionfs: new lower inode mtime

Hi , For reasons I will not go in to does anyone know if you can convert a RedHat RHEL4 box to CentOS 4 ? I am hoping this possible with our re installing . If it if what do I need to do to get the system to run yum instead of the RedHat updates. Thanks Arun -------------- next part -------------- An HTML attachment was scrubbed... URL:

Dear All, My apologies for asking my question on less appropriate list. I did ask it on centos-mirror at centos.org, but that list is really low traffic (and slow response probably - I only got acknowledgement of my post...). On the other hand, I'm sure there are many public mirror maintainers on this list who may help me with my trouble. Upon replacing faulty machine hosting public mirrors

Hello, I am trying to establish a mirror, and when I execute the rsync command, it only creates the directories and selected files. It does not download the entire iso collection or repo files. I am running CentOS 5.4 (which i will update soon as my host does not have a 5.6 or 6 image), and my IP address is 125.7.120.87, being hosted in Sydney, AU. Any ideas or suggestions would be appreciated.

I'm searching for the SRPM corresponding to this installed RPM. % yum list | grep gfs2 gfs2-kmod-debuginfo.x86_64 1.92-1.1.el5_2.2 It is missing from: http://msync.centos.org/centos-5/5/os/SRPMS/ What I need from the SRPM are the patches. I'm working through some issues using the source code, and the patches in the RedHat SRPM

Hi rsync devs and users, I want to use rsync to synchronize home directories on two PCs. It works fine if I start rsync after working on a host each time I leave. But instead of operating modes "host1 -> host2" and "host2 -> host1" I would like to have a mode "host1 <-> host2" to allow synchronizing at any time -> Scenario: - on host1 files A,B have

It wouldn''t be proper to start my first post here without congratulations and thanks to the ZFS team for such an impressive piece of work. Anyway, on to my query. I''ve been trying out ZFS, with a particular focus in reducing latency in a specific application. This application has a fair amount of random writing going on in the background (which, of course, ZFS will make

I've been working on adding support for the PPC 440/450 "embedded" cores to the PowerPC backend. These are used on IBM's Blue Gene L and P supercomputers, but are also used in other environments (like on the Xilinx Virtex-5). Here is my first patch. I'm new to LLVM, and so I apologize if this is the wrong way to do this [the online docs seem to imply that a patch should be

Hi everyone, I am writing a small tool that will compare a file on my machine with the the same file on an rpm repository and then give me a diff. E.g. # rpm-file-diff /etc/samba/smb.conf will show a diff output so that I can see at a glance what changes I have made to my local smb.conf file. I already know about rpmdiff but that compares whole packages and not files. Anyway while fiddling

Another question is about the performance of coverage's at-exit actions (dumping coverage data on disk). I've built chromium's base_unittests with -fprofile-arcs -ftest-coverage and the coverage's at-exit hook takes 22 seconds, which is 44x more than I am willing to pay. Most of the time is spent here: #0 0x00007ffff3b034cd in msync () at ../sysdeps/unix/syscall-template.S:82 #1

Hi All. I've found: This directory (and version of CentOS) is depreciated. For normal users, you should use /6/ and not /6.3/ in your path. Please see this FAQ concerning the CentOS release scheme: http://www.centos.org/modules/smartfaq/faq.php?faqid=34 If you know what you are doing, and absolutely want to remain at the 6.3 level, go to http://vault.centos.org/ for packages. Please keep

Hello, I have few questions about coverage. Is there any user-facing documentation for clang's "-coverage" flag? The coverage instrumentation seems to happen before asan, and so if asan is also enabled asan will instrument accesses to @__llvm_gcov_ctr. This is undesirable and so we'd like to skip these accesses. Looks like GEP around @__llvm_gcov_ctr have special metadata

Hi- Tried 0.99.9-test2 -- had to go back. Various problems in the log. Here's one: Apr 10 08:56:25 mercury mem[10754]: imap(user0): msync() failed with index data file /users/8b/user0/Maildir/.INBOX/.imap.index.data: Cannot allocate memory Apr 10 08:56:25 mercury mem[10754]: imap(user0): Corrupted index data file /users/8b/user0/Maildir/.INBOX/.imap.index.data: Missing location field
