Thirdlane platform General Questions

We are bringing up a TL installation soon and have a question regarding opertaing system support. I see that the bundled TL ISO comes with CentOS, but i am curious about a 64 bit installation. I took a look at the CentOS website and they do have a x86_64 version available for download. Also if i remember correctly the TL ISO comes with CentOS 4.x? is that correct? will it support 5.x of CentOS?

I have a feeling sticking to the TL ISO and its provided OS will be the best bet.

Just trying to feel out our options.

I run CentOS 5 with TL but I am not running x86_64. I tried running asterisk with x86_64 in production a couple years ago and realized that the bugs I experienced were unlike others. I found myself in the minority of bug reporters so getting bugs fixed that resulted in deadlocks and dropped calls never came. Simply running 32-bit on the exact same hardware put an end to the deadlocks and dropped calls.

my advise is to poll the community at large. Its never fun to be in the minority when it comes to bug prioritization.

for what its worth a 32bit install should sufficiently handle all your pbx needs.

We run a mix of x86_64 and i686 on CentOS 5 and CentOS 4. Typically we have no problem with any configuration.

That says, eeman raises an interesting issue, and I thin we might try switching back to i686 for one of our switches that might be having some call stability issues.

I am running MT on a dual opteron 64 with a RAID 0 on CentOS 4. It screams. Do yourself a favor and only work with CentOS 4 until the next major release.

I would advise that setting up 64 is a manual operation, and you don't want to do it from the TL isos. Get the OS running on its own, then manually install webmin and load PBX manager from that.

We are about to release a new CentOS 5.2 based ISO with extra configuration options (RAID), and choice of versions of Asterisk (1.4 - 1.6).

Anyone interested in beta testing?

Not a whole lot, particularly... Just that using an ISO implies reinstalling the machine in order to upgrade (at a minimum taking it offline in order to boot from the CD to upgrade it in place). We run RHEL 5.2, with Asterisk, DAHDI, and Webmin installed from source and most of the dependencies pulled from rpmforge. I also tend to upgrade pretty frequently (Asterisk security updates installed as soon as I can get a convenient downtime window after they come out, etc). If I get the new webmin module I can just drop in that and the new version of Asterisk without having to reload everything else or have a multi-hour downtime window.
