Hi, for me, centos is the choice of OS for enterprise usage for two reasons: 1. you receive longer software/repository updates 2. rpm / yum updates/upgrades can be taken back. So you can rollback on a privous software version you used. Both is not present in ubuntu/debian/apt based OS's, afaik. In both, ubuntu and centos, in combination with ceph, you should anyway use a (more) recent kernel with your customer optimizations for your individual hardware / software requirements. And for ceph, it does not matter if the software in the repository is not up2date. You anyway wont install anything else but ceph on ceph nodes. Same goes for the community support. Since you are just using ceph, you wont need community support ( except of the ceph community ). So all in all, i dont see a single reason to pick ubuntu, right now, especially for ceph-only environments. The only thing what is a bit biting, is that/if ceph specific systemd files are not working, not complete or for what ever reason not working as its expected. That already happend in ubuntu, as well as in centos. -------- BUT in the very end: the only smart choice is to use the OS YOU are most familar / fine with. In case of emergency/troubleshooting, its ALWAYS best, if you work with a known system ( and dont need to rely too much on searchengine input/support of 3rd party ). So, in the very end, take that, what you can work with -and like most ! :) -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 05.05.2016 um 14:26 schrieb Jan Schermer: > This a always a topic that starts a flamewar > my POV: > > Ubuntu + generally newer versions of software, packages are closer to > vanilla versions > + more community packages > + several versions of HWE (kernels) to choose from over lifetime of the > distro > - not much support from vendors (for e.g. firmware upgrades, BIOS, > binary packages) > > CentOS+ more "stable" versions > + more enterprisey (unchanging) landscape, with better compatibility > + generally compatible with RHEL, means that binaries and support are > usually provider by vendors > - frankenpackages of ancient versions patched ad nauseum with > backported features > - documentation lacking on "specialities" that are not present in > vanilla versions (kernel is the worst offender) > > My experience is that Ubuntu is much faster overall, can be better > "googled" or subverted to your needs, LTS versions seldom break during > upgrades but I've seen it. > CentOS is more suitable for running software like SAP or application > servers like JBoss if you need support.
