The snapshot has then been transferred to a different server, e.g., /storage/backup/data-set@today. With zfs rollback storage/backup/data-set@today, the resulting mount-point will...

    Mounting ZFS filesystem (44/53)

    It's taking forever to mount and for the system to come online. Last time it happened, the hard disk was more or less full. I am not sure it is again out of space, Poudrière had now run in days. I run Poudrière (in a jail) on it and do zfs snapshot & destroy everyday. Chromium took over 44hrs...

    Solved ZFS Permissions Problem with zxfer (zfs receive)

I'm trying to follow the man page and the pull example in Advanced...

    ZFS Horribly slow performance after reboot when attaching HDD with geli and mounting pool

    Hey all, I'm getting a little uncomfortable in my current situation: FreeBSD 11.3, using zfs.

Right...

    ZFS Current ZFS + NFS performance

    In the near future I may have a requirement to provide storage for a couple of VMWare servers that are currently running NFS off an ageing Netapp appliance. As good as the Netapp probably is, the chance of it going wrong worries me as I don't really have a clue what I'm doing with it, and it...

    ZFS GELI/ZFS volumes automount

    Hi, I have tried with both Mate and KDE, but it looks like there is no automatism to mount encrypted volumes. Something like LUKS volumes automount on Linux. It shows a nice dialog box asking for the password and then does all its things. I have a usb "data disk" that I insert when needed, so it...

    When you install FreeBSD using the Auto ZFS option, GPT labels and GPT UUIDs are disabled in loader.conf: kern.geom.label.disk_ident.enable="0" kern.geom.label.gptid.enable="0" The only reference to labels being disabled that I could find is from a 5-year-old PC-BSD bug report complaining...
