Advice on partitioning a Dell MD1200 disk array
by Tony Molloy 05 Sep '12

05 Sep '12

Hi, I've just got possession of a Dell PE R720 with 2 MD1200 disk enclosures. Both MD1200 are fully populated with 12 x 3 TB disks The system will basically be a student file-server running CentOS 6.x serving various size files from small c programs to multi gigabyte audio and video files over GB ethernet. The first MD1200 will be configured as the NFS disk. The requirements are for 6 fixed equally sized partitions, one for each cohort of students. For this I was thinking of splitting the MD1200 into 2 RAID5 arrays with a hot spare each. Then partitioning each into 3 ext4 partitions. The second MD1200 will be used to backup the first, using BackupPC and for other storage purposes. As I won't know the storage requirements for the "backup partition" and they will probably change over time anyway. I was thinking of using LVM for it. So how to partition the MD1200 for LVM. I don't want to put all 12 disks in a RAID5 and put a LVM volume on it. Can I split it into 2 RAID5 and have a LVM volume spanning both. Any suggestions. Just remember I'm due to retire at the end of this month so this will be my last big job for the Dept. And due to financial constraints I will not be replaced. So I will be handing this machine over to a co- worker who is basically a Windoze admin with only a basic knowledge of Linux so nothing too fancy. ;-) Thanks, Tony -- Tony Molloy CTO, Dept. of Comp. Sci. University of Limerick Limerick. Ireland

Booting and ignoring sysct.conf...
by John Doe 05 Sep '12

05 Sep '12

Hi, just wondering if there was a way to boot while ignoring sysctl.conf... A colleague messed up one parameter, that ended up crashing the server at boot time. Booting in single was not helping. Fixed it by booting on a live CD and modifying the sysctl file but, it would be convenient to know if there was a kernel parameter to add to the grub entry or something to bypass it... But I see it is run in /etc/init.d/functions, so maybe it is not avoidable. Thx, JD

CentOs6- Use nscd for offline LDAP
by Johan Vermeulen 05 Sep '12

05 Sep '12

Dear All, I'm thinking about connecting the 15 or so laptops in our organisation to LDAP. Now I'm trying to use nscd in order to enable the users to work when being offline. The test laptop is installed for this occasion, updated CentOs6.3. Following the advise I found on a few posts I modified */etc/nscd.conf : * server-user nscd logfile /var/log/nscd.log debug-level 3 reload-count unlimited paranoia no enable-cache passwd yes positive-time-to-live passwd 3600 negative-time-to-live passwd 20 suggested-size passwd 211 check-files passwd yes persistent passwd yes shared passwd yes enable-cache group yes positive-time-to-live group 3600 negative-time-to-live group 60 suggested-size group 211 check-files group yes persistent group yes shared group yes enable-cache hosts yes I also Modified*/etc/nsswitch.conf*and changed the order after passwd - shadow - group : passwd: ldap files shadow: file ldap group: ldap files *This seems to work.* * When stopping nscd, LibreOffice gives the EM: /The application cannot be started. A general error occurred while accessing your central configuration. /*When starting nscd LibreOffice just works. *When enabling nscd a can su to an LDAP user from root, without nscd the user does not exist. *But the problem I'm having* is I was kinda hoping to log back in from a locked screen or from hibernation, in other words continue a running session. Or who knows, even start a new session. Can anyone help me make this work? Thanks for any advise Greetings, James -- IT-medewerker Caw De Kempen Opensource Software is the future.

Recover software raid 10 on CentOS 6.3
by Jacob Hydeman 04 Sep '12

04 Sep '12

The setup is 4 1TB drives running RAID10. I was using the Gnome Disk Utility to verify the integrity of the array (which is a 500MB mirrored md0 and the rest a R10 md1). I believe one of the drives is bad but prior to the system going offline it showed that 2 drives were detached from the array but healthy. A reboot results in a panic complaining that not enough mirrors are available. Is there a method to mount this array from a live CD so I can export the VM images. I have backups of the important ones but I'd lose 18 hours of data and a new PBX VM that was just finished but not backed up yet. I've been reading and testing various suggestions from the web but until I get this unit back up all phones and E-Mail are down, which leads to a slight panic, which makes it difficult to read and understand :) The backup server is at another location so I'm trying to recover first. Any direction would be appreciated. Thanks, Jacob

Gradually adjust NTP sync over time?
by Sean Carolan 04 Sep '12

04 Sep '12

Suppose you have server A and server B. Server B is running 60 seconds too fast, while server A is accurate. Is there a way to gradually move server B's time back into sync with server A, without making a drastic, immediate change to the clock? In other words, we would like to 'smear' the difference across several hours or days to ensure there are no drastic changes in timestamps, etc.
