Software Raids Questions (I have only ever used hardware?)
by James Bensley 28 Sep '09

28 Sep '09

Hey List; I have no experience with software RAIDs; at work we only use hardware RAIDs and I'm looking to implement, probably a RAID 5 set up at home for a media server however I have a few questions; I have three 1TB drives in various places; one is inside a USB caddy, one is inside my PC and in is inside my existing media centre. Is it possible to add these three drives to another one to give me 4TBs of space in a RAID setup without having to wipe the drives as in my experience which is only with hardware RAIDs, I have normally formatted all the disks before creating the RAID? The thing is, if that is the case I will need to transfer 3TB of stuff somewhere (I have an idea where, if this were the case), make the RAID then transfer it all back but I really don't want to do that as I'm sure you can imagine. Also, if the above where possible; in the future could I then keep adding more drives and expanding the RAID? Note: Obviously I know for this to be a RAID 5 I would need extra drives but the RAID level is undecided, but provisionally I think it will be RAID 5. On a side note, I cobbled together my new media centre running Ubuntu but I might move it back to CentOS, it was originally CentOS and that is my favoured distro, but I would rather not now it is running Ubuntu happily I'm just wondering, is this all achievable in Ubuntu? Granted people on the CentOS mailing list might not know that, but if anyone knows that it is all achievable in CentOS then I would move back? Thanks for reading.

Pbone says there is a package for FC6, and also offers an rpm from sourceforge. That may be a possibility too.

IP aliases of CentOS Guests not accessible running 2.6.18-164.el5xen
by Devraj Mukherjee 28 Sep '09

28 Sep '09

Hi all, First of all I am posting this on two lists for a reason, because the issue being reported by me could be because of a change delivered by a Kernel update or due to Xen. I have recently managed to update all Xen Guest domains running CentOS 5.3 to the latest bunch of updates + Kernel. My Xen host also runs the same CentOS 5.3 updated to all recent packages. The Guest images in concern had IP aliases assigned to them. Everything worked until I ran the updates and restarted. Since I have restarted the aliased IP addresses are no longer accessible from the outside world, they can still be accessed from all machines (guest virtual machines) in the subnet (ping, services like http). I have removed all firewall rules to test if that would have effected it without any change (any the fact that I can access them within the subnet proves its not the firewall). Is there anything special I have to do to enable aliasing? May be this is a Xen issue? I am suspecting the Xen host, but not sure how to go about proving this. Any information would be greatly appreciated. My Guests do run fail2ban (delivered via atrpms) and iptables (allowing only HTTP, HTTPS and SSH) connections. PS for obvious reasons I am not posting IP addresses and routes etc first up, I can make that information available if required. -- "The secret impresses no-one, the trick you use it for is everything" - Alfred Borden (The Prestiege)

Using yum with CentOS-2 mirrors
by Matt Arnilo S. Baluyos (Mailing Lists) 28 Sep '09

28 Sep '09

Hi all, I was having yum errors while updating our CentOS-2 box. Further reading lead me to a readme file on the mirrors (http://mirror.centos.org/centos-2/readme.txt) and it gave me the new URL to use for CentOS-2 mirrors. I have edited /etc/yum.conf with the new URLs but I'm still having issues with yum giving me "ValueError: unpack list of wrong size" errors. Has anyone been able to update their yum configuration to be still able to use yum? How were you able to configure it? I understand that CentOS-2 has now reached its EOL but we have a legacy application that won't run on newer distros. -- Stand before it and there is no beginning. Follow it and there is no end.

External Backup Systems?
by M. Hamzah Khan 28 Sep '09

28 Sep '09

Hey everyone, My home server just had a disk failure a few weeks ago and like a lot of people I haven't ever really made backups on a regular basis. So I was looking into backup solutions which will save me from this situation again. Now I have Bacula setup, and backing up my files onto my home server. Although this works great, I have one issue: The disk in my server was the one that actually failed, and so, even with RAID1, could fail again. So to get around this I wanted to backup to external media aswell. I don't really think external hard drives are that great considering they are just as reliable as internal hard drives which would be pointless as RAID1 should be reliable enough in that case. Backing up to DVDs are quite unreliable too, a simple scratch could render the backup useless. Also it would require quite a lot of DVDs to backup my data (at least 500GB!). The only other option I could think of is to use tapes, but this option can be quite pricy for a home user. So I was wondering what you guys use for external backups for a home system containing at least 500GB worth of important data? Regards Hamzah -- M.

rsync not getting all files?
by Scott Ehrlich 27 Sep '09

27 Sep '09

I ran rsync on a combination of Ubuntu and CentOS systems and it doesn't seem to grab all files, such as .cshrc or .bashrc (and they do exist). This makes me wonder what other files rsync may be missing, and how do I tell rsync to grab those missing files? Thanks.
