[CentOS] Ext4 safe for production use?
As part of my current research for upcoming setup, I started reading up on filesystems (was actually looking up fencing which leds to node crash and file integrity on different fs) to see if there would be any significant improvement to using a different filesystem for networked storage. e.g. glusterfs on top of ext4 nodes. Initially, the reading suggested that ext4 would provide a significant performance boost. Quite possibly since it delays write longer, latencies of the network storage is hidden even better especially for temporary files. After subsequent reading, it seems that the cost of the massive delay allocation that could blow up really bad in the event the system crash. However, this may also be limited to poorly written applications, i.e. since some massive arguments last year over Firefox 3.0, sqlite and ext4 problems, ext4 now detects situations where it should flush to disk immediately to avoid zero length files on crash. Assuming I'm using the most likely disk writing applications I'm using is KVM, exim, dovecot, mysql and postgresql, would ext4 be safe for production use or should I stick to ext3? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Put it in an local repo and install it with yum in the %post section of the kickstart. This will be exactly the same as installing with yum after an install, so you can test it outside of kickstart.

Second, you'll notice that the diagram and the table do *not* mention L3 caches, so the architecture's a bit different. Finally, note where the article says, If an error is recoverable then it does not raise a Machine Check Exception (MCE or mc#) when detected. The recoverable errors, broadly speaking, are single-bit ECC errors from ECC-protected arrays and parity errors on clean parity- snip If an error is irrecoverable then detection of that error will raise a machine check exception (if the bit that controls mc# for that error type is set; if not you'll either never know or you pick it up by polling). The mc# handler can extract information about the error from the machine check architecture registers as before, but has the additional responsibility of deciding what further actions (which may include panic and reboot) are required. A machine check exception is a form of interrupt which allows immediate notification of an error condition - you can't afford to wait to poll for the error since that could result in the use of bad data and associated data corruption. --- end excerpt --- So, it is, in fact, serious, and non-recoverable, so they have a problem with their hardware, and you've paid for a service that they provide, including hardware that's supposed to be up 99.whatever you paid for% of the time.

The current xulrunner-devel (1.9.2.4-9.el5) actually has 46 dependencies (91 on x86_64). The previous version (1.9.0.19-1.el5_5) had 28.

You might also add native (untagged) vlan 1 to the existing tagged vlans - then you can set up a pxe-booting network on vlan 1 and once things are installed you can add the tagged vlan interfaces and optionally remove the IP address from the untagged (base eth device) interface. No, these are per port settings and do not require coordinated changes to any other switches, switch ports, or hosts. With the proposed config, untagged data between the host and switch would be processed as VLAN 100 - unbeknownst to the host. The host would have the base eth device setup without VLANs - this is VLAN 100. Any additional VLANs are setup as normal eth.vlanXX devices. As was said, this is just one way of doing things. Personally, I might propose that PXE setup be performed on a dedicated VLAN, once the server is setup it would then utilize a different set of VLANs for communication. --Blake ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Perhaps there's a third-party repo with updated packages that I haven't found? CentOS is based on RHEL (RedHat Enterprise Linux). When a base version of RHEL is released (eg RHEL 5.0 [CentOS 5.0]) the versions of all of the software is 'frozen'. RedHat, however backports security and bug fixes (which CentOS passes along). So although the *appearent* version of Postfix is 2.3 in the repo, it will have the esentual security and bug fixes of the current version (2.7.1). [It may not have any feature enhancements of the current version though.] Fedora is the *beta testbed* that feeds into RHEL. Fedora is generally NOT recomended for production servers, since it is not generally stable enough. Also, its support lifetime is short (like about a year or less). This means you need to to fresh installs for each new version of Fedora and all sorts of things will likely break (means your production server will be down for days or even weeks every year -- not really good for business!). RHEL / CentOS has a support lifetime of 7 years (from the X.0 release). There are third-party repos (epel, rpmforge, elrepo) with some updated packages, but you need to be carefull -- it is possible to cause dependency conflicts that could break things. There is also the CentOSPlus repo that has selected updated packages as well.

Re: [CentOS] how to properly change the timezone
Stephen Harris wrote: I have a Centos 5.5 server with no GUI installed. I have several times changed the timezone by copying the correct file to /etc/localtime, however something keeps changing it back. I'm not sure if this is a yum update or what. Without installing the graphical tools, how can I update the timezone in such a way that the /etc/localtime file won't keep getting clobbered. /usr/bin/system-config-time (from the system-config-date RPM package) It will work in text mode. (Essentially /etc/sysconfig/clock is the config file that also needs updating) Thank you. I'm hoping that the problem was caused by not updating /etc/sysconfig/clock which I have done now. I'm guessing that when the tzdata package gets updated it copies the latest timezone file to /etc/localtime, based on the timezone specified in /etc/sysconfig/clock. I tried yum installing system-config-time, but it wanted to install two pages worth of additional dependancies. I'm trying to keep my server installations a little less bloated. There where no symbolic links. All I had done was to copy the correct timezone file to the file /etc/localtime. Some have warned that symbolic links are a bad idea, because then if something tries to update the timezone it may clobber the data file in /usr/share/zoneinfo.

Not possible for any other box to be assigned the same ip internally via dhcp and definitely not the same Internet ip. Perhaps you care to explain why BOTH vlan interfaces stopped working? The odd chance that two other boxes each took one of the other ip address? I'm you have another Linux machine on the same network that is not having the same problem, try installing arpwatch. It should pick up the conflict with 30mins or so. The box with the problem just so happens to be the only box using bonding, 802.1q and a four port Qlogic Netxen NIC. I think the chances of there being a problem between these three more likely than some 'ghost' boxes getting assigned the same ip addresses when I am the only admin around. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
