Freebsd add disk to zfs pool When a pool is imported, the /boot/zfs/zpool. It returns "cannot remove da2: only inactive hot spares, cache, top-level, or log devices can be removed". Next, pick one or more disks you want managed in the ZFS storage pool. Zfs in freebsd/freenas doesn't allow the removal of devices that don't have redundancy. If set labels here (-l <label>) use labels for following commands. It's not harmful but the system tries to import the original pool, recreating the zpool. I would like to use a ZFS raid-z3 pool consisting of 14x 12TB SAS or SATA drives (this will be a rare-write/many-reads situation). x server? Introduction: ZFS is a file system for FreeBSD operating system. You're mixing ada0 and ada1 in your commands. Moderator. I've read a lot about ZFS and all that but I'm still a bit confused about how I'm going to set this thing up. Jul 7, 2018 #4 After you got a name you can then proceed to the actual import process. Let's assume our pool is called zroot (a mostly common name). That is, the pool was created like this: zpool create pool0 raidz ada0 ada1 ada2 This means the disks have ZFS disklabels, rather than FreeBSD disk labels. You can check if your has the correct ashift value by doing: move to raidz3 vdevs (tripple disk parity) add a hot spare that can immediately start rebuilding in the event of issues replicate your pool, which you're doing (async raidz20, haha!). There are 2 important things to keep in I need to move the /var/log to a non-root pool for performance reasons. zpool import newpool, if necessary zfs attach newpool <12TBdrive1> <12TBdrive2> zfs scrub newpool. 1-RELEASE-p3 - ZFS 2 disks mirror (AHCI controller) Data pool (zdata) - 6 disks raid10 (raid 1+0 n x 2-way mirrors) (LsiLogic SAS controller) 'zdata' pool created with da* (Ignore the root on ZFS part but pay attention to the note at item 7. I can't figure out how to do this in a bsdinstall script without modifying bsdinstall itself. 2-RELEASE, where /boot is on a 'freebsd-zfs' partition on the same disk as the bootcode, boots without issue. 12. To import a pool you must have a version of OpenZFS installed that supports all enabled features. To create a RAID-Z pool, specifying the disks to add to the pool: # zpool create storage raidz da0 da1 da2 I would like to migrate this pool to new ZFS mirror pool which I can create from two new ssd disks. Another way would be to add new disks to a pool, One could (but shouldn’t) have a pool with a raidz2 vdev of four disks, then add a two disk mirror, making the pool like a hunchback, then add a single disk (which would act like a raid0 vdev) then add all sorts of vdevs. ) constructing the data requires both disks to be intact and available. Practice first on a virtual machine, and then on the live system. an image of a single zfs disk is not going to "contain" Presumably I need a pool name, but don't have one. 4. If you attach disks that contain a ZFS pool, or were part of a pool, to a new computer, zpool import should scan all disks and show you what it can find. Other details that zfs-snapshot(8), zfs-send(8) and zfs-receive(8). If you need to enhance the speed (=IOPS) "beyond available hardware disk IO" of, especially, spinning platters(*), ZFS also offers the possibility of adding a SLOG or Separate intent LOG SSD; see How do I configure an encrypted ZFS pool to store data on this disk? How can I add encrypted ZFS pool on FreeBSD 11. The "ashift" value is only set when creating the vdev, so you don´t need to create another NOP device for a replace. This means using physical disks for zfs should be cross-platform. 7T) 7813629549 407586 - free - That linked guide is outdated. ) Then, after doing any partitioning you need, just do zpool replace . If you’re familiar with the iostat command—a core tool on FreeBSD, and a part of the optional sysstat package on Debian-derived Linuxes—then you already know Mar 1, 2016 · Also, the system is not reading the pool details from disk as the pool only has one device, and that is unavailable. All attemps to import, including zpool import -F -T 12855264 -R /mnt -f rpool, resulted in Dec 4 12:56:54 1. In my case, takes 1-2 days with moderate load on the pool. g. I reinstalled FreeBSD 13 but this time on the two 8 TB HDDs instead of the NVMe SSD. Aug 31, 2017 · If I did, I would have either made a 7TB pool of two mirrors, or put 4 disks in one mirror, then removed the old disk. The pool was created like this. 7. If the controller doesn't support those, then create a bunch of 1-disk RAID0 arrays. The only thing to consider is each pool has feature flags that specify which features have been enabled on the pool. Now attach the new drive to the zroot pool: I'd be careful connecting a disk directly used by ZFS (i. if I go out and buy an equally sized disk to add to the pool, will zfs automatically reorganize the data so existing data is striped? Or will the two disks be in the same pool but two completely vdevs? I'm a little confused. Both the old and new pool was created using whole disks. ZFS overwrote the primary table at the beginning of the disk but the secondary table at the end survived. It only makes gpart(8) happier. With the ‘gpart’ command we can check those partitions are existing. The ZIL on disk is intended to function as a quick temporary storage facility for data that needs to be saved in a non-volatile manner but has not yet been written to its final location on disk as part of the normal ZFS data structures. Jun 13, 2022 · It's not a requirement but to tidy up the system. Donate to FreeBSD. zfsboot is installed in two parts on a disk or a partition used by a ZFS pool. ZFS and the ZFS In order to fix this I did a zpool export <pool> and then ran zpool import -d /dev/disk/by-id <pool> This seems to have kinda worked, but rather then grab the disk-id, it seems to have grabbed the wwn. The idea is to grow the pool by adding more disks, exchange them by larger ones - using the benefits of ZFS, or when the day come simply physically move the whole data pool only into the new machine, but not to copy data between pools anymore. Idea was to have an encrypted disk to share data between FreeBSD and Debian (and maybe even WSL). I think it may offline a disk if it gets too many errors but I'm not 100% on that, or what the limit is if it does. Another, older system, upgraded to 13. config: NAME STATE READ WRITE CKSUM zroot DEGRADED 0 0 0 raidz1-0 DEGRADED 0 0 0 gpart add -t freebsd-swap -s 32G -l freebsd-swap ada0; swapon /dev/ada0p2; gpart add -t freebsd-zfs -l system ada0. For testing purpose, I set up a test environment with loopback Use zpool attach tank existing-disk new-disk to add a disk to an existing disk in the pool,so it becomes a mirror if it was a single disk vdev, or a three disk mirror if it already was a two disk mirror. The new pool uses the same disk devices (da1-da8) as the orphaned pool. Debian root is on an EXT4 file system. I have been looking at chassis like the SuperMicro SC846BE1C-R1K03JBOD. I didn't find any documentation on how to replace disk in this situation or information was deprecated. You cannot add the same disk (or partition) to more than one pool. For FreeBSD this answer on serverfault seems to be helpful. ) # geli init -l 256 -s 4096 ada0p1 ada1p1 ada2p1 (enter passphrase) # geli attach ada0p1 ada1p1 ada2p1 (enter Adding the disks to the pool zpool add san mirror ada0 ada1 mirror ada2 ada3 gpart create -s gpt ada8 gpart create -s gpt ada9 gpart add -t freebsd-zfs -b 2048 -a 4k -l log0 -s 8G ada8 gpart add -t freebsd-zfs -b 2048 -a 4k -l log1 -s 8G ada9 gpart add -t freebsd-zfs -a 4k -l cache0 ada9 gpart add -t freebsd-zfs -a 4k -l cache1 ada9 Add them to the zpool. Would it be better (or neccessary) to partition the disks before with gpart or doesn't it matter if I use the whole disks My understanding is ZFS puts all kinds of metadata on the disks that keeps track of this stuff. very different RAID copies everything. The system on the USB disk may complain about failed cache file import of the original pool because the new pool is a exact clone and in the zpool.

FreeBSD sees the secondary table and warns you about the situation. Exact copies of the partition tables and partition sizes, of course, but different, larger disks. Now I want to add another 4TB disk (ada1) to enlarge the size of the mirror to 4TB. Considering that ZFS is well supported under FreeBSD and Linux systems, ZFS may seem to have been the ideal filesystem for this scenario. If the new SSDs are larger than the existing drives, then you can do zpool replace [pool] [device] [new device] for each disk, waiting for one to complete before doing the next. 0-RELEASE The partition layout generated by the installer for both disks, ada0 and ada1 are: root@odissey:~ 2048 4194304 2 freebsd-swap (2.
