SATA Raid 5 and losing a drive
by Andy Green 11 Apr '06

11 Apr '06

Hi Folks - Using CentOS on a server destined to have a dozen SATA drives in it. The server is fine, raid 5 is set up on groups of 4 SATA drives. Today we decide to disconnect one SATA drive to simulate a failure. The box trucked on fine... a little too fine. We waited some minutes but no problem was visible in /proc/mdstat or in /var/log/messages or on the console. I ran mdadm --monitor /dev/md0 and no problem was shown. We rebooted still without the drive and finally mdadm --monitor reported that the array was running in a degraded state. We reconnected the SATA drive and still nothing was reported and nothing happened with the raid state according to /proc/mdstat. I expected the box to keep on trucking but to become freaked out with warnings all over the shop. What should I have expected in this case and what should I do to become aware of evil events like the drive melting remotely? -Andy

Postfix on VLANs
by Andrew Vong 11 Apr '06

11 Apr '06

Hi All, I'm having some problems getting postfix to relay mail. I'd appreciate any tips. Perhaps there are some settings which I may have missed, somewhere. The postfix mail server is on VLAN 250 (192.168.250.0) whilst I have several other users on other VLANs (e.g. 91, 92, 93, etc... 192.168.91.0, 192.168.92.0, 192.168.93.0, etc...). So, if I had a PC sitting on VLAN 91 with IP 192.168.91.1, I am unable to relay mail BUT checking mail via POP3 works fine. In /etc/postfix/main.cf, I have set the following:- mynetworks_style = subnet mynetworks = 168.168.91.0/28, 127.0.0.0/8 Do you know what setting I may be missing? Thanks. Best Regards, Andrew

Issues with aacraid
by Karl Fischer 11 Apr '06

11 Apr '06

Hi there, I'm currently trying to install a server with Centos 4.3 x86_64. I have issues installing drivers from a Driver disk, I got a driver(2810SA) from the Adaptec site, I started it up with "linux dd" It reads the disk fine .... I can see the aacraid module in the list but as soon as I choose it. Then I get a screen saying "Do you wish to load more Driver Disks?" I can see in the logging that it can't find the driver it also gives a "Can't find a valid FAT filesystem on dev fd0". I have dd'ed the image ... it is a ext2 Filesystem and used RAWRITE. Is there more that I can try ? Any Suggestions ? Thanks Karl -- ----------------------------------------- Karl Fischer Drone, Human and Gnome User I support 10x10.

gtkmm-2.4 for Eiciel?
by Yanik Doucet 11 Apr '06

11 Apr '06

Hi everyone, I'd like a nice frontend to setfacl and getfacl. I'm getting lost with those ACL commands. I've found Eiciel which is a nice gnome frontend to setup ACLs. The problem is it need gtkmm-2.4, and centos seems to have gtkmm-2.0 only. Is there a safe way to upgrade? Do you have a repo to suggest? Or anyone knows of another graphical ACL editor with more conservative dependancies. Thanks Yanik

yum repository conflict resolutions
by Dave 11 Apr '06

11 Apr '06

Hello, I'm setting up a test mailserver on centos4. I want to use stable rpm packages but ones that don't have conflicting lib requirements. I've got the standard yum configuration with one excdeption i've enabled the centosplus yum repository. I've read that dag's repository has a package i'm going to need courier so i figured to set that up. Here's my problem, if i then do a yum update on this box and more than one repository has a package say kernel which does it get? Or, if a package has a library dependency and that is installed and it conflicts with another, how would this be resolved? Sorry about the confusion any help appreciated. I'm also going to possibly have a need to roll out custom-made rpms not sure yet on that one, and it's been a while since i did them, rh7 i think was the last time. Does anyone have a Centos-specific howto on this not for modifying an existing srpm, but for creating an rpm from tarball? Thanks. Dave.

redirecting some addresses with sendmail
by Tony 11 Apr '06

11 Apr '06

I have a fully working cyrus+sendmail mail server hosting all users for foo.com. Company foo has been acquired by company bar and it has been decided that bar.com is the new domain of choice. The administrator of bar.com has added a pile of redirects to send various user(a)bar.com addresses so they come up to my server at foo.com. My users have changed their From: addresses to user(a)bar.com and we have a basic working system. However, if one user in former company foo mails another user in the same office their mail now goes offsite to bar.com's mail server and is then redirected back in again, which works but is bad for bandwidth. Ideally I'd like to teach sendmail that a subset of bar.com users are now local. However if I try this in the /etc/aliases file, I get the warning "cannot alias non-local names". Has anyone got any better ideas how to do this- or a better suggestion as to where I should ask this question again? -- Cheers, Tony

question about mouse and kvm switch
by mrrs 11 Apr '06

11 Apr '06

Greetings all: I have a CentOS 3.6 and 4.3 box sharing a kvm switch. Switching from the 4.3 box to the 3.6 and back again, the mouse stops responding. The keyboard works just fine, and I can ssh into the box. I have tried <ctl><alt><bksp> and while it does restart the x server, it doesn't seem to affect the mouse. Is there something I can run to get the mouse recognized again short of restarting the computer? thanks markus __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
