Is there anyone having problems with NVME device (Intel 750 PCIe 400GB/1.2TB) with the latest updates from OmniOS? r151018 (258cc99) and r151020 (b5b8c75). We are getting a lot of (H) errors on those devices. When i revert back to r151018 (95eaa7e) all is working fine. I guess it has something...

Thanks for the replies :) An option that we also are looking at (MB/CPU platform): Supermicro | Products | Motherboards | Xeon® Boards | X10SDV-7TP4F Has onboard tons of features, but maybe not compatible (Like the 10GB card from the Xeon D platform?) The onboard LSI controller is an older...

In my list i've used the 4K (native) SAS drives from HGST 0F22794 HUS726040AL4210; or do i need the 512e version (0F22795 HUS726040AL5210)? As i've read 4K native is the best choice for ZFS?

Currently we are using NFS for storage protocol to our other VM servers or better choice ISCSI over NFS?

Load on the system will be different VM's (Exchange/SQL servers, VDI desktops) around 40-50 VM's (Servers and VDI) I'm considering a 8x 2-way mirrors, but fault-tolerance must be high so that's why we choose for now a 3-way mirror setup (5x 3-way) but again a 8x2-way is also an option. 70% OP of...

I'm planning a new ZFS (Omnios/NAPP-it) storage server build; need some advice (if needed) on my planned setup. Main goal is a MAIN storage server that delivers good IO/Throughput and maximum safety of data. An all SSD system is not an option atm ($$ and storage capacity) 1 x Supermicro...

Wow big loss when used odd numbers on RaidZ2. 3x7 (raidz2): 31.9T [32T /36T] 2x11 (raidz3): 42.9T [43T /48T]

Oohh.. this is odd... have OmniOS (latest stable) running with on all drives LZ4 compression; turned it off now.. now i can reach 1106 MB/s (bonnie Seq. Read). Turned LZ4 compression on: 235 MB/s Both WITHOUT read Cache SSD. CPU stays steady on 60% idle when compression is on.. Also better...

zdb | grep ashift ashift: 12 ashift: 12 ashift: 12 ashift: 9 Think the 9 is the SSD read cache drive or boot drive? EDIT: ashift: 9 is rpool (boot)

btw new pool is ashift=12 (old samsungs where indeed ashift=9) What about 2x11 in RaidZ3

Yeah now i noticed a lot of space wasted. got usable 40.4TB --> df -h: 32TB. I used zfs send / recv to copy data. So u're advice is to have 2x10 RaidZ2, will i have less space wasted due to block missmatch? I've got 22x RED'2 avail.. got not 21 drives in use and 1 Hot Spare

So i've upgraded my 14 x SAMSUNG 2TB green drives to 21 x WDC RED 3TB's. first i had the samsungs in 2 x 7 (RaidZ2), now i have 3 x 7 (RaidZ2). Previously i reached 300-400Mb/s speeds while reading data, but now with the new drives i only get 100-150Mb/s (bonnie benchmark Seq. Read) Same server...

Ok thanks for the information, but is it also possible to do this "offline" the last inceremental, don't want to have any changes in the meantime.

Thanks! Is it also possible to do an snapshot clone on a live system, and after that an incremental?

Hi there, im using ZFS now for a while, but now i need to expand the pool. Currently im using Hitachi 7K3000 2TB drives (512b) and i allready have the new ones Hitachi 7K4000 (4k), now i want to copy/clone the complete pool to the new pool; cause i can't replace the old drive with a new one due...
