It's just one large single RAID5, so it's slightly less than 4.5TB. So, what you're saying then is to either put a small single HD to install CentOS, or make the array smaller than 4.5TB. I could easily make something much smaller, say ~1TB, install CentOS on that. Once that's finished, create the rest of the array as another array at the size that I need. Could use LVM to stitch it all together... I'll give this a try, thanks for the help. Mark

AMD 64 - I20/ I20_blocks
by Karl R. Balsmeier 13 Jul '06

13 Jul '06

I'm trying to install either 32-bit or 64 bit centos 4.3 and I keep getting an error: "No valid devices were found on which to install filesystems". In checking BIOS and RAID, everything seems fine, but I just found some research about I20. An alternative would be the i2o_blocks module. How can I install CentOS 4.3 x86_64 using i2o_blocks? How do I instruct the boot prompt to find this driver and get me past the above error? Even in 32-bit I still get this error as well. -karl

tftp question
by Jerry Geis 12 Jul '06

12 Jul '06

I have tftp running on a computer. done with yum install tftp and yum install tftp-server. The computer has 2 network cards in it. Everything else on this computer is working fine. My tftp config is : # description: The tftp server serves files using the trivial file transfer \ # protocol. The tftp protocol is often used to boot diskless \ # workstations, download configuration files to network-aware printers, \ # and to start the installation process for some operating systems. service tftp { socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -v -s /tftpboot disable = no per_source = 11 cps = 100 2 flags = IPv4 } When I am on the computer and I "tftp localhost" an request a file it will give it to me. when I "tftp localip" it will say connection timeout, when I "tftp INTERNETIP" is says connection refused. note localhost, localip and INTERNETIP are all the same computer. I have the firewall allowing tftp ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:tftp ACCEPT udp -- anywhere anywhere state NEW udp dpt:tftp What might I be missing here? Thanks, Jerry

Problem with CentOS 4.3 and ldap
by Myron Williams 12 Jul '06

12 Jul '06

I currently have a server with centos 4.3 setup to do email. I use sendmail as the receiving agent and Dovecot as the pop/imap server. Users authenticate off of a openldap server. Under a light load things appear to work fine. However under a moderately heavy load connections are left open in a waiting state. This causes some email to bounce with user unknown, users authentications fails with bad username/password all with valid accounts. I am trying to figure out what the cause is to fix it but with out success. By restarting ldap and the ldap server I can minimize the problem because the connections get reset. I find nothing when I google on the subject. I don't believe this is a problem with the ldap server because I have a Fedora core machine using it without problems. Any help or ideas on how to track down the problem would be appreciated. Myron Williams

Hardware Raid cards RAID 0 / 1
by Chris Heiner 12 Jul '06

12 Jul '06

Last week we tried to install Centos on a brand new HP ML150 G2 with AIC-8130/ Marvell SATA Raid card and it was a no go. We tried a few other flavors of Linux as a test and all had trouble as well. Unfortunately time didn't permit so we opted for a Windows solution to get the box into production. We have never had a problem with IDE and Embedded SATA (Non Raid) Next time we want to research the SATA compatibility a head of time. Any suggestions? What cards have worked for you? Thanks.

Freenx full screen mode problem fixed in 0.5.x?
by Steve Bergman 12 Jul '06

12 Jul '06

In early June, there was an update from freenx 0.4.x to 0.5.x in centosplus. It broke full screen mode for Linux clients. I am aware of the ctrl-alt-f workaround. But I have quite a few users at branch offices who depend on NX and with employee turnover and all, it has been a source of confusion for us. Has anyone come up with a fix so that fullscreen works without crtl-alt-f? I've searched the freenx/knx list and have found no mention of anyone there having problems. Just the centosplus version. I prefer to continue using the CentOS-provided package, though. Thanks for any assistance. -Steve

Speaking of 3Ware/RAID/SATA/9550SX...
by Mark Schoonover 12 Jul '06

12 Jul '06

I just built up a server running CentOS 4.3, and trying to boot from a 3Ware 9550SX-16ML, 16 port card. This system has 9x500GB drives, AMD Opteron, Tyan K8SD mobo and 1 GB of ram. I downloaded the latest (9.3.0.4) driver from 3Ware, and after a couple of botched attempts, I got CentOS installed. In my two botched attempts, the problem was X hanging during the formatting of the drives, so I switched to another virtual screen while formatting took place, and the system didn't freeze. My problem now is the system won't boot. I know this is not exactly a CentOS problem, I'm just hoping some kind sole would help me outta this overworked fog I'm in. When the system tries to boot, the cursor just sits there in the left corner of the screen flashing. Nothing happens. I am probably missing something very simple, that will cause me great public embarrassment, but I really don't care right now. Yes, I set the bios to boot from the 3Ware card, and CentOS install did show grub stage(1) and stage(2) getting installed. After that, I'm not exactly sure where to look. I googled, and went through the 3Ware KB, but not much luck there... Thanks! Mark Schoonover IS Manager American Geotechnical V: 858-450-4040 - F: 714-685-3909 - C: 858-472-3816

Raid 1
by CentOS List 12 Jul '06

12 Jul '06

Hi, Is there a tutorial on how to setup raid 1? I like to install CentOS 4.3 on a 160GB SATA drive and do a mirror on another identical 160GB SATA. Thanks
