Do people use moose boxes for other roles ? Sometime ago I made a moosefs linux ISO cd (not a respin) however the installer wasn't insert cd and job done. Taking it any further was beyond my capabilities. Is such a thing needed or desired ? Any collaborators Steve |

The chunk server daemons are very low footprint for system resource requirements. Enough so they are suitable to coexist with other system services. Where if you have a cluster of physical machines each with a local disk, just making every compute node also be a chunk server for aggregated file system capacity. Most of the time lately though we put everything in virtual machines on virtual machine hosting platforms now. Which I guess I kind of feel it is ot as efficient to have the chunk servers spread out everywhere, all VMs are backed by the same SAN anyway, so the performance over spread out disks goes away right. So lately I create a Virtual machine just for running the chunk server process. We have a "standard" of using CentOS for our VMs. Which is arguably kind of wasteful to just use it as a chunk server process, but it is pretty much set and forget and appliance-ized. I have often thought about creating a moose fs stand alone appliance. An embedded nano itx board in a 1U rackmount chassis, solid state boot, and a minimal linux distribution, with a large sata drives. Both low power and efficient, out of our virtualized platform. At least probably cheaper to grow capacity than buying more iSCSI RAID SAN products :P But this is still in my to do some day pile.

Travis, Yes I guess the world is moving on with VM's only something ive recently dabbled first ESxi and Proxmox which I currently have a vm mounted that is stored on moosefs. As only a hobbyist/home user most of my moose boxes are on various recycled PC's bits however most have ssd boot. I do have one atom based chunk although just in regular case for cheapness. I did some years back try 1u cases with the intention of having a rack but found them very noisy and the hardware expensive for home use and now have a custom homemade walk in cupboard with ample power points and LAN points for each shelf. With all cabling hidden behind including patch panel. Yes a standalone unit was in my mind when I dabbled with the distro some years ago with the idea of inserting the cd and answering little more than one question to determine the boxes role. Again hardware has moved on with usb stick more the norm for booting and ssd drives. Steve -------Original Message------- From: Travis Hein Date: 05/01/2012 16:13:03 To: moo...@li...

Hi, We run the chunkservers completely from memory, they boot from USB and only use a small partition of the USB drive for the graph data so that the history isn't lost between reboots. Every chunkserver has 6x1TB disks and 3GB of ram and there are startup scripts that initialize new disks on boot if required, so a new server can just be put into the rack with a USB stick plugged in and it will clear all the disks and setup for MFS if it is not like that already. /Oli On 5.1.2012, at 16:11, Travis Hein wrote: > The chunk server daemons are very low footprint for system resource > requirements.

On a related note - we were using USB sticks to boot chunkservers, but now we are using network boot for that. On chunkservers themselves is only data. This allows us to very quickly add new servers - just add new node in configs and plug the server in. In our experience using network boot is faster and safer than USB sticks (and also cheaper).

PXE netboot is a great choice when managing a bunch of identical machines, especially MooseFS chunk-servers that don't need any particular variation in the config files, and you can use the entire disks for the volume! I had a good experience with Debian Live http://live.debian.net/devel/live-boot/ (unfortunately this isn't in production but not for technical reasons): every machine bootstrap via PXE, download from a TFTP server the generic kernel and initrd with live-boot scripts, that downloads a squashed rootfs via HTTP and mount it. The last init.d script will mount the available machine disks on know locations and mfs-chunkserver is started. When a software upgrade is required, we simply generate a new squashed rootfs with updated software, test it under a virtual machine, and when you are sure it's working, reboot every node in sequence. -- Giovanni Toraldo http://gionn.net/ |

We actually use NFS root, allowing us to have single read only base FS for every chunkserver. We can upgrade, if needed chrooting to base on master and then restarting all chunkservers. Also this system allows using different mfshdd.cfg for each chunkserver, allowing us to remove/add disks if they get hardware errors.

NFS is a good choice but may be a single point of failure if the server is not redundant. With PXE, each node is independent after the first boot, since their entire rootfs is kept compressed in ram (or can be written to disk after download, thanks to live-boot script support). In addition, rootfs auto-enable aufs support, so it's possibile to change files manually or via a custom post-boot script, that get lost on reboot or that can be saved on a custom partition/usb/flash. -- Giovanni Toraldo http://gionn.net/ |
