Pierre, What was the "old" storage? Was it local or NAS? This question is to
compare against your new storage. How do you have the 8x8TB disks
configured? A pool of mirrors? RAID-Z2? Are you 1G or 10G or faster between the
hosts and the NAS?MikeSent from my Galaxy

NFS as primary storage, performance issues Hi all,We're working on upgrading
our storage solution to a proper networkattached storage.Before this, we had an
NFS share on some mounted disks on the managementserver. Our new setup is a NAS
running TrueNAS (zfs) with 64 GB ram and8x8TB, 7200 rpm hard disks mounted to
cloudstack over NFS.It seems the performance is however much lower than before,
resulting insomewhat unusable virtual machines. In VMs, IOPS can be as low as
<10 IOPS,vs 100 with the management server setup.Is there a recommended setup
for primary storage to yield betterperformance?All the bestPierre,kthcloud
