Hints for performance tuning ZFS on Omnios:ġ) Enable lz4 compression to increase write speed. funny detail: i was the person that informed Gea (napp-it developer) of Omnios a year ago. Overall i am happy with the transfer from freenas to napp-it, next week i will convert our second storage box to omnios+napp-it. What i like is that is possible to create a mirrored usb boot stick with napp-it.
NEXENTASTOR INSTALL TO USB DRIVE UPGRADE
I still have to upgrade the zfs pool version.

The interface of napp-it is not as polished as freenas but does the job well. I started a backup of that clone with the same nfs store as target => 70Mb/s which is very acceptable considered that the vm and backup are on the same store. Then a made a clone of a vm to the napp-it zfs store. In omnios i have installed the network and after that the wget.installation of napp-it.Īfter logging in into napp-it i have imported the zfs pools, enabled nfs on 1 dataset and set the acl on everyone rwx.Īfter that i tested again with a backup from local storage to the napp-it nfs storage => ~250Mb/s, this is about the same as freenas. In the bios i set the usb stick as primary boot. Installation was straightforward, i only had to disconnect the 2 LSO m1015's and the 2 Zil SSD's because the omnios installer did not see the USB stick.Īfter the omnios installation i connected the M1015's and the Zil SSD's. Replaced it with a 32GB blank usb stick and installed omnios via an ipmi mounted omnios iso. Yesterday i have removed the freenas 9.1.1 usb boot stick from the storage unit. I have promised to post the results of omnios+napp-it+nfs+proxmox. I have tried to mount the NFS shares as UDP instead of TCP, this did not change the slow read problem. Seems like the NFS read speed is very poor. When i make a backup of that vm the backup speed is very fast at ~250Mb/s. To do some testing i have made a clone of a small vm to the local Proxmox SSD.

The vms reside on an NFS share on dataset 1 and the backup NFS share is on dataset 2. When making a backup of the vms the backup speed is max 10Mb/s which is very slow for the above hardware. Proxmox nodes: Xeon 1240v2, 32GB, 60GB SSD (supermicro hardware)įreenas node: Xeon 1220L, 32GB, usb stick freenas install, 16x3TB hdd (dataset 1 = 6 x 3TB in raidz2 + 1 Intel S3500 80GB for ZIL, dataset2 = 10 x 3TB in raidz2 + 1 Intel S3500 80GB for ZIL).Įach proxmox node has approximately 5 vm's which reside on an NFS share on dataset 1 on the Freenas node. I have a 3 node proxmox 3.1 cluster with freenas 9.1.1 storage backend.
