    USB mass storage devices slow to be detected

    I have recently setup FreeBSD 12.0-RELEASE on my HP Pavilion 15-p051us. Most of the hardware works correctly, however one major exception is USB, most specifically with mass storage devices. When I connect a mass storage device to my laptop (on either one of the two USB 3.0 ports or on the USB...

    Installing FreeBSD under KVM with VirtIO

    This is a public "note to self" that I hope will be useful to somebody out there. This evening I wanted to install FreeBSD in a VM under KVM on a Linux VM-host. Also, when I install FreeBSD with ZFS (Read: Always), I like to partition and setup the disks by hand via the "Shell" option in the...

    I set a user and master password on a SATA disk drive and I can not unlock it since. After setting the pw, I've frozen the drive with camcontrol security -f Any idea? I can issue camcontrol inquiry successfully, but most other camcontrol commands fail. Especially, I can not unlock the drive...

    camcontrol standby weirdness

    Other SSD drive appears to have been "downgraded" from SATA 2 to SATA 1

    I have two allegedly identical SanDisk SATA 3 SSD drives connected to my SATA 2 motherboard as a ZFS mirror. Until yesterday both these drives were happily operating in SATA2 mode at 300MB/s but now one of the drives (ada0) is only running in SATA 1 mode at 150MB/s. I've swapped the drive...

    Other LSBLK(8) Command for FreeBSD

    Hi, as we all know there is no single command to show storage devices on FreeBSD system. Some grep the dmesg command, some check /var/run/dmesg.boot file, some try camcontrol command and so on ... as I struggle to create any empathy for Linux systems I really like the lsblk command and I always...

    Solved Best practise to access drives with unique identifiers?

    My new FreeBSD 10.2 server consists of one SSD for the base system, several HDDs for data storage and a hot swap bay which I use for backups. All drives are encrypted with geli and I use ZFS on all internal disks. I have written a small script to automatically attach encrypted disk, import ZFS...
