If you just want to keep the pool alive and safe, then you can attach another drive to the single disk, FreeBSD's GEOM system has always allowed the drive's write-cache to be enabled regardless of how the drive is accessed, which made this a non-issue on FreeBSD. In such a scenario, If I had 7 disks, I would create a pool like this: pool: tank state: ONLINE scan: none Since receiving a couple of disks I have now created what should become my final file server, and with that I have created a ZFS pool by running zpool Bobi B. My plan is to create a zpool on a USB stick for files that I use in between workstations (more of a learning project for ZFS). eli da7. Sorry for the messages as above # After that I did this: Sep 4, 2018 · ZFS doesn't allow you to just create a new ZFS file system, for example, on /usr/ports unless both /usr and / are each their own ZFS file system (created via zfs create). If not, you can use this as a template to add more disks etc. Note that there is no way to undo the creation of a multi-vdev pool, make sure you get it right or you'll have to recreate your pool from scratch using a backup if you mess up something. 3 # zpool create -f storage da0 # zfs set mountpoint=/backup storage See the changes we have made so far # gpart add -t freebsd-zfs -l storage -a 1M da0 make: a) Create a partition.

FreeBSD Manual Pages man apropos apropos home | help ZFS(8) System Manager's Manual ZFS(8) NAME zfs -- configure ZFS datasets SYNOPSIS zfs-?V zfs version zfs subcommand [arguments] DESCRIPTION The zfs command configures ZFS datasets within a ZFS storage pool, as described in zpool.

The newly created pool is mounted at /new-pool. It's going to matter if you use 4 disks (with 2 for fault-tolerance; 2 effectively usable) or 10 disks (2 fault-tolerance; 8 usable). 0+ - original ZFS import, ZFS v6; requires significant tuning for stable operation (no longer supported) 7.

The pool names mirror, raidz, draid, spare and log are reserved, as are names beginning with # zpool add zroot /dev/ada3 invalid vdev specification use '-f' to override the following errors: mismatched replication level: pool uses raidz and new vdev is disk # zpool add -f zroot /dev/ada3. Second, use zpool status to examine the current ZFS pool. b) Leave a space of 1MB at the beginning to make an alignment on the disk that supposedly improves performance. Home; About. If you go and use the raw disk device like in your example commands, ZFS will use the whole disk and clobber your partition table. Each dataset can be customized with specific properties, such as compression or quotas. Being quite new to FreeBSD and especially ZFS, this filesystem seems to squarely I set up a couple of jails and ports trees with iocage and pot and poudriere, which all use zfs. I have started ZFS.

If the properties are not set with the "zfs create" or "zpool create" commands, these properties are inherited from the parent dataset. eli da1. That allows you to take a 2-disk mirror vdev, add a third disk, resilver the data onto that disk, then "zfs split" the disk off the mirror, turning it into a stand-alone pool.
