Hi, Swen. Do you test with direct or cached ops or buffered ones? Is it a write test or rw with certain rw percenrage? Hardly believe the deployment can do 250k IOs for writting with single VM test. 2 февр. 2018 г. 4:56 пользователь "S. Brüseke - proIO GmbH" < s.brues...@proio.com> написал: I am

AW: KVM storage cluster

2018-02-01 Thread S . Brüseke - proIO GmbH
I am also testing with ScaleIO on CentOS7 with KVM. With a 3 node cluster with each node has 2x 2TB SSD (Samsung PM1663a) I get 250.000 IOPS when doing a fio test (random 4k). The only problem is that I do not know how to mount the shared volume so that KVM can use it to store vms on it. Does an

a bit late, but: - for any IO heavy (medium even...) workload, try to avoid CEPH, no offence, simply it takes lot of $$$ to make CEPH perform in random IO worlds (imagine RHEL and vendors provide only refernce architecutre with SEQUNATIAL benchmark workload, not random) - not to mention a huge lis

Thx Ivan for sharing, no reboot issues because of problematic Intel microcode ? This is just Meltdown fix for now, and btw congrats on courage to do so this early (since no final solution yet). FYI, CentOS/RHEL has already patched everyhing (kernel and qemu/libvirt) but we are also on Ubuntu..

Actually, we have this feature (we call this internally online-storage-migration) to migrate volume from CEPH/NFS to SolidFire (thanks to Mike Tutkowski) There is libvirt mechanism, where basically you start another PAUSED VM on another host (same name and same XML file, except the storage volume

Vladimir, the original error seems as MySQL timeout for sure (I assume because of HAPROXY in the middle), and we also had this setup originally (MGMT server using HAPROXY on top of galera nodes...) but this has confirmed to be issue, no matter what we changed on HAproxy or Mysql, and at that time

No, the primary storage is local (in this case), but the primary storage isn't being involved, as I'm creating a template from a snapshot which resides on a secondary storage. The snapshot's size is ~300GB. On Wed, Jan 31, 2018 at 06:18:43PM +, Simon Weller wrote: > Is your primary storage
