by David Hrbáč 04 Mar '10

04 Mar '10

Hi, I have made complete rebuild and backport of Firefox 3.6.1 and Thunderbird 3.0.1 to CentOS 5. Packages come with language packs, debuginfo packages, xulrunner etc. I'm looking for QA testers. Upgrade from distro versions works pretty fine. Thanks, David Hrbáč

YESS. It prevents the tty error from showing up and asks me for a password as expected. BUT, how do I then automate the entering of the password? John Kennedy mentioned using expect which I've used before but found it to be 'finnicky'. I may have to look at it again... Changing settings such as sudo configuration or ssh config may be daunting since I have a large number of systems(150+) that would need to be modified. :-/ --Tim

But I guess that comes with the territory. 8-) The ATA Secure Erase command is generally faster but more difficult - see http://ata.wiki.kernel.org/index.php/ATA_Secure_Erase Ben

removing a md/software raid device
by Bazy 04 Mar '10

04 Mar '10

Hello folks, I successfully stopped the software RAID. How can I delete the ones found on scan? I also see them in dmesg. [root@extragreen ~]# mdadm --stop --scan ; echo $? 0 [root@extragreen ~]# mdadm --examine --scan ARRAY /dev/md0 level=raid5 num-devices=4 UUID=89af91cb:802eef21:b2220242:b05806b5 ARRAY /dev/md0 level=raid6 num-devices=4 UUID=3ecf5270:339a89cf:aeb092ab:4c95c5c3 [root@extragreen ~]# mdadm --detail /dev/md0 mdadm: md device /dev/md0 does not appear to be active. [root@extragreen ~]# mdadm --detail /dev/md1 mdadm: cannot open /dev/md1: No such file or directory Thanks, Bazy

Resync raid1 from disk with unreadable sectors
by Mindaugas Riauba 04 Mar '10

04 Mar '10

Hello, After some fiddling with the server now I have broken RAID1 with the "current" mirror on the disk with few unreadable sectors. If I try to re-add other disk to the mirror resync goes till those bad sectors and then starts from the beginning. And so on. Is it possible to somehow force resync to continue even after errors? Manual resync with dd would require a bit too long downtime. If it is impossible to force resync I'll probably manually rsync all the files from the old broken disk to the new one. Mindaugas

splash screen resolution
by Michael Klinosky 04 Mar '10

04 Mar '10

I installed CentOS 5.3 on a desktop box, and I'm having a problem with the splash screen resolution (during bootup). I suppose that it somehow got configged when I set the GUI's screen (I run in level 5). I think that, in finding the highest res for the GUI, I went past the monitor's capability. But it's good now. During boot, I get a funny 'double' display (2 pointers, 2 sets of text). I can't find where to change it (thru the gui or manually). And, yes, I did try searching (on google.com/linux and the CentOS wiki). I didn't see anything in /boot/grub/grub.conf that would set the res. I read about removing 'rhgb'; I tried it, and at least it uses an appropriate resolution. But, I'd like to use the graphical boot screen. How do I fix this?

SSH Remote Execution - su?
by Tim Nelson 04 Mar '10

04 Mar '10

Greetings All- I'm about to embark on some remote management testing and need a way to login to a remote system running CentOS 4.x/5.x via SSH, su to root (using a password), then execute a command. I currently login to the boxes using key based SSH like this: ssh -i ~/remote_key admin@$REMOTEIP Then, I SU to root. However, if I try to do this automatically like this: ssh -i ~/remote_key admin@$REMOTEIP 'su -l' I'm getting: "standard in must be a tty" So, how am I able to remote login using SSH, su to root, then execute a command as root? All comments and suggestions welcome. Thanks! --Tim

Raid0 with no backups? For real? Backups are for sissies; running a hara-kiri RAID demands *not* having backups. Or did the kamikaze pilots have parachutes?
