    H310 Mini no raid mode with ZFS?

    Good day everyone, I have recently purchased a Dell R320 server with the H310 mini card. This card has a no raid mode where the disks show up individually (AFAIK, it does not create a raid 0 array for each disk). I would like to know if using this mode is safe for ZFS? BTW, the mini card cannot...

    Slow NFS/SMB/AFP, but fast SCP read performance

    Hi! My FreeBSD 11.2 box has the strange behavior that copying a file via NFS, SMB, or AFP is always capped at exactly 60 MByte/s. However, copying the same file to the same client via SCP immediately hits GBit line speed at 110 MByte/s. It shouldn't be a hardware limitation, I can read the...

    ZFS can't import zroot pool after failed freebsd-update (unresponsive tx->tx state)

    I did freebsd-update from 11.1 to 11.2-RELEASE, but I did not have enough disk space and "freebsd-update install" stage failed (No disk space error) - so my system is screwed.
