    Operation not permitted from dd

    I need to update the bootsector after upgrading zfs pool. In 10.3 the command to disable the Operation not permitted error was: sysctl kern.geom.debugflags=0x10 But that doesn't seem to work in 11.0: root@crayon2:~ # sysctl kern.geom.debugflags=0x10 kern.geom.debugflags: 16 -> 16...

    zfs default compression algorithm

    I'm a bit confused as to what compression my system uses From man zfs: compression=on | off | lzjb | gzip | gzip-N | zle | lz4 Controls the compression algorithm used for this dataset. Setting compression to on indicates that the current default compression...

    ZFS System crashes on "zpool status tank" on 11.0-RELEASE-p2

    I have a zfs pool encrypted with geli. After a clean system boot, I mount the geli devices, then do zfs status tank so the pool is discovered. The system panics. I found and old thread documenting a similar issue (involving SSDs and GELI), but it still seems to be happening. Here's my stack...

    NFS3 sharing multiple filesystems

    I have a ZFS file-system (project) that contains numerous ZFS file-systems (project001, project002...project120). How can I share this with NFS3 as just a single share? On Linux there is a crossmnt option that does this. I have separate file-systems as I need to be able to snapshot each...

    camcontrol standby weirdness

    I'm trying to spindown disks in a zpool to save energy costs. This concerns a home NAS setup. I've broken in down to a single disk. Here I want the disk to go into standby mode after 20 minutes of idle time: camcontrol standby ada2 -t 1800 What actually happens is the disk spins down...

    ZFS ARC cache larger then the pool itself?

    Hello, Just of curiosity did anybody noticed this interesting stuff? I got this VM with 16G RAM and 6GB disk. The disk has only one pool - zroot and looks to me like the ARC cache takes more memory than the pool size is. root@system:~ # zpool list NAME SIZE ALLOC FREE EXPANDSZ...

    ZFS Finding /user/home in pool

    Hi, I'm new to ZFS and loving it! I have a pool (pool0) which was created when I moved from Linux. It has my home directory on it from my first adventure with BSD. Playing with TrueOS I ended up with a new install on two mirrored SSDs (tank). Meanwhile I still have my old /usr/home sitting on...

    /boot/entropy and zfs bootpool

    When installing a new FreeBSD 11.0 with zfs root, the installer creates 2 zfs pools and puts the contents of /boot in zfs:bootpool/boot. /boot is a symlink pointing to /bootpool/boot Normal boot process then does not mount bootpool (nice little security extra there) so the /boot symlink points...

    Solved ZFS with SSD L2ARC

    Hello, I am building a PC currently. I want to use 1 HDD and 1 SSD as ZFS file-system. The problem is I don't know how to do it manually. I want to use SSD as cache to HDD. From what I've read I understand that I should use L2ARC partition on SSD. Is that correct? And where can I find how to...

    To be or not to be

    This Sunday, my FreeBSD box has entered some weird state. This machine is following 11-stable, and, - after calling delete-old-libs maybe, I don't really know - a lot of modules and commands fail on missing libjail.so.1 I checked out this file within /lib and ls confirmed that the file was...

    Other Add external storage eSATA with disk enclosure and zfs

    I've got a FreeBSD 11 box running and now I'm in the process of adding storage to the machine. The machine is a mini-itx box and therefore I don't have any physical space left to add internal drives. I'm running ZFS on the system today and I want to run ZFS with raidz on these new drives as...

    Solved stable/11 buildworld ZFS linking issues

    I am running 11.0-PRERELEASE and am attempting to upgrade to the latest revision of stable/11. When building world I get linker issues involving ZFS libraries. Some experimentation I have done indicates that the builder is actually trying to link to my own system's ZFS libraries. As a test I...

    ZFS Migrating ZFS pools between GNU/Linux and FreeBSD?

    I have a 3 x 500 GB drive ZFS pool left after a prior installation of Arch Linux and I would like to learn whether there are any mechanisms that would allow me to safely convert the pool in question to one compatible with FreeBSD. For now I received tons of errors about "unsupported" features...

    ZFS Replacing entire pool?

    I would like to replace all 3 spinning drives of a raidz pool with (smaller) SSDs: the smaller SSDs will still be more than adequate for my storage needs, and should be significantly faster. The system has a limited number of SATA ports (4): 1 is in use for the system drive (which is already an...

    Solved Recovering bad loader.conf

    Greetings, I was reading a tutorial (now lost) that suggested adding a vesa="YES" directive to my loader.conf for one reason or another. Apparently, this was no good as the bad setting is preventing me from successfully booting into FreeBSD. What I would like to do is to use the LiveCD to...

    ZFS retaining /home after reinstall on zfs

    I'm new to FreeBSD and for the moment it seems easier to reinstall to a known condition after battling with xorg for a while. I had a fully working system and all of a sudden X does not find my video card. Not sure if it was related to trying to get some Wine up and running. Anyway, I've decided...
