    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    Humm so? OP spoke of WD Green, and I did mention that 2TB+ disks using AF are concerned.

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    and there was the non-alignment issue as well ... Well, end of the day, 4k drives under a 8 ashift pool take a performance hit under certain circumstances.

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    Performance hit under certain circumstances. Sectors are physically 4K long, but the HDD report them to the OS as 1/8th (512 B). For example, consequently, the OS could ask the drive to write 512 Bytes of data, because it thinks the physical sectors on the drive are exactly that size. The...

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    All 2 TB+ drives on the market using Advanced Format still emulate 512 B sectors. Therefore the issue is still ongoing, and users still need to use the known tricks to avoid problems with ZFS (modified zpool executable with hardcoded ashift=12 or gnop command under BSD environments). For WD...

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    For the ZIL part, it is because NFS is making use of synchronised writes, to the contrary of SMB. I guess if I could not solve my issue, I will revert back to SMB.

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    Hello again guys, I currently another more minor issues since to move to Solaris 11. Little background again: following my reinstallation, I decided to switch from SMB to NFS file sharing protocol (I have only one Windows machine left on my home network, and wanted to make better use of my ZIL...

    Wouah I am impressed, it solved my problem ! Guess I inadvertently changed some settings during my tinkering. Thank you so much Gea

    Hello hardforumers, I am using a Supermicro X8SIL-F mobo with two Intel NICs onboard for my Solaris 11 ZFS box. The adapters were working perfectly fine under Solaris Express 11 (no need for manual configuration, working immediately out of the box). Following a HDD failure incident, I took...

    3TB / 4TB drives for zfs (4k advanced format)

    Best thing IMHO is to force 4k sectors on the Solaris pool using the modified zpool commands that circulate. Some people even offered the modified code for this, so you could just compile your own 4k compatible zpool command. I did this one year ago with EARS drives from WD and no issue so far...

    To raid0 2 ssds or.... not to?

    I do not think you will encounter any kind of bottlenecks using one only 6 Gb/s SSD on real life scenarios, therefore not really sure it is worth to deal with the limitations of RAID-0 arrays just for the joy of benchmarking. This plus extra level of gambling implied with using two OCZ Sandforce...

    New ZFS storage server

    On a separate note, as the others told you, regarding the size of your various vdev, you should split your storage by using multiple RAIDZ-2/3 vdevs. A big unique vdev of 40 TB is not recommended (cf ZFS Best Practices).

    Zfs system disk failure question

    If the main pool is lost, you have to reconfigure the groups and users that have the corresponding rights to access the folders/files in the storage pool to make the shares working, however shares definitions are kept.

    New ZFS storage server

    L2ARC cache: Basically, the L2ARC will hold all most frequently used blocks from the pool for read cache purposes. No need to have enterprise *reliable* storage (by that, I mean being concerned about SSD's wear leveling issues -> cheap but fast SSD based on MLC is typically what you're...

    quick zfs question hopefully - RAIDZ or RAIDZ2?

    You're right on that one, but resilvering is stressful because of the raw amount of I/O in short timeframe used to recreate the array (like a scrub, yes).
