Getting info on hardware RAID
by Matt Arnilo S. Baluyos (Mailing Lists) 27 Aug '07

27 Aug '07

Hello everyone, I'm doing an audit of all our servers here (there aren't that many maybe around 5-10) and one of the things I'm doing is taking note of each server's hardware specs (processor, memory, etc). I can't seem to figure out how to get the information for the hard drives. The drives are in a hardware RAID5 array and are all SCSI types. I would like to get each physical SCSI drive's specifications (like, disk capacity). Also, we have another server that also uses Hardware RAID and there's a RAID5 and a RAID1 array in there and I would also like to get as much information as I have on them. How do I get this information from the console? Is this possible? I don't have physical access to the servers and can only log in remotely. Thanks, Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

"Site down for maintenance" - How is this accomplished?
by Matt Arnilo S. Baluyos (Mailing Lists) 27 Aug '07

27 Aug '07

Hello everyone, Although we use CentOS primarily on our servers, this query is actually more of a general networking question than something specific to CentOS. In the next week or so, we shall be migrating our in-house servers to a data center. While we're doing that, we'd like to show a "Site down for maintenance" message while the servers that hosts our websites (we have around 15 sites hosted btw), are down. So, how is this accomplished? While I can probably hack something on our name servers, I'm sure there are people on this list that have been doing this and could give some recommendations as to the best practices for this type of task. Thanks in advance, Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

NX on 4.5 vs 5.0
by Scott Moseman 27 Aug '07

27 Aug '07

NX connections to my 4.5 server give "cramped" looking fonts (as if the resolution were wrong). Connections to my 5.0 server look great regardless of the resolution. Both use GNOME. Is there anything I can do to the 4.5 servers to increase the quality of the NX connections? Thanks, Scott

We have several large projects will use ORACLE 10Gr2 database with CENTOS 4.X. Does anyone have performance report on 32 Bits O.S. (with 32 bit ORACLE) VS 64 bits? Thanks. ____________________________________________________________________________________ 杜絕網路駭客，保障帳號安全 - 馬上設定 Yahoo!奇摩安全圖章http://tw.info.yahoo.com/seal/index.html

Avoiding mounting other installation's partitions and volumes
by Ioannis Vranos 27 Aug '07

27 Aug '07

OSes: CentOS 5.0 x86, CentOS 4.5 x86. Hi, I have CentOS 5.0 x86 installed on an IDE HDD. [john@localhost ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 224G 8.5G 204G 4% / /dev/hdc1 99M 16M 79M 17% /boot tmpfs 506M 0 506M 0% /dev/shm I want to install CentOS 4.5 x86 on another hard disk, but from my past experience, when using one installation, it also automounts the logical volumes etc of the other installation during boot. How can I avoid this?

by Dave 27 Aug '07

27 Aug '07

Hello, I've got a centos5 box that originally did not have x on it as it was headless. It's purpose has now changed and x is now needed. I'd like to install it and gnome preferably without having to reinstall the os to get the ease of install, it just works when anaconda does it, is this doable? Thanks. Dave.
