    Best way to set up 24-drive ZFS NAS?

    Hi all, Your wisdom and experience would be highly appreciated with the following query. I am setting up a 24-drive NAS (QNAP TS-h1283XU-RP). The hardware seems decent (Xeon E-2236 6-core 3.4 GHz, 128GB ECC RAM). The system volume will reside on an m.2 drive. For cold storage, there are 12...

    Virtualization and ZFS

    I would be interested in your opinion because I am migrating all my machines to Virtualized solutions (mostly Proxmox VE, still have one ESXi Box). For the Host (or AIO using OmniOS + Napp-IT) filesystem I'm without doubt using ZFS. Does it matter the FS that the Guest will be using? Of it...

    Is it possible to shrink, in-place, ZFS pools?

    I have an Intel NUC NUC8i7BEH with a Samsung 970 Pro 512GB M.2 NVMe SSD installed in it. My OS is Linux Mint Cinnamon 64-bit 19.2 . I'm running off of ZFS root with two pools : rpool and bpool, where bpool is everything under "/boot". Just yesterday, while performing an update, the update failed...

    Bunch of 2 TB HDDs, best RAID/array solution?

    I've been coming into a lot of 2 TB enterprise drives recently and was thinking of getting an array going. Looking for an inexpensive (sub-$100) solution to build an array, ideally maximizing storage space with a bit of redundancy (RAID 5/6?). This would primarily be for media / general file...

    ZFS, Largeblocks, Recordsize, and VDEV Drive Counts

    Hey all, So, I've been in a middle of a project of one by one replacing and resilvering my old 4TB drives in my pool with 10TB drives in order to grow it in capacity. My plan is to use my old drives, 12x 4TB WD Reds in a a spare backup server and use them for backups. In the old days, prior...

    35 Disk ZFS Pool, Go or no?

    Ok, I am about to upgrade my last set of 2TB hard drives to 4TB and am wondering how bad of an idea is it to make just one large pool instead of 3 smaller vdevs Right now I have 3 vdev at 11 raidz3 disk each (11x4TB, 11x4TB, 11x2TB), I want to go to one 35x4TB raidz3 + hot spare (36 disk...

    Napp-it AiO NAS wont boot after power outage

    Hey all, we have an AiO Napp-it NAS running in a JBOD. We had to use a USB drive to run Omni-OS since we didn't have enough SATA ports. We had a power outage recently and now the server will not come back up. Looks like the boot structure is corrupt. If I were to setup another USB drive with...

    Building a (low cost) Linux-based ZFS High-Availability Clustered NAS

    I thought I'd share this here since I've used bits and pieces of advice from the forum in the past. I was frustrated with the limitations and cost implications of using commercial ZFS solutions in a high-availability setup. NexentaStor, QuantaStor and Zetavault either had cost or support...

    Home lab ZFS Server Build

    I'm in the process of building out a ZFS file server for three XenServer Hypervisors. This is in one of the HP Prolait G6 2U chassis with 25*2.5 SAS bays sitting in the front. (2*L5520's + 48GB memory) These all are hooked up to an LSI HBA (not sure of the model, it's one of 'em that plays nice...

    ZFS high cpu load with low io and cpu usage

    Hi, We are using zfs on one of our servers. Both deduplication and compression features of zfs are also enabled in it. We were trying to migrate a vps disk from an ext4 server using 'DD', but the migration process seems to be resulted in an increased load on zfs server and hence the migration...

    ZFS and 512n vs 512e vs 4kN drives

    Guys, I will try to keep it very short as I tend to get into unnecessary details. My ultimate goal is to choose between using 512n, 512e, or pure 4kN drives for a new ZFS storage appliance that will either consist of eight 4TB drives in four mirror VDEVs, or eventually Raidz2 in order to...

    ZFS Pool config for new SAS expander chassis

    Arriving in the mail today is the 45 bay Supermicro SAS expander chassis I got off eBay. My plan is to fill it with 3TB drives, I already have about 25 drives and am looking to purchase some additional white label drives off eBay in the next few weeks. My current thought is 3 15 drive RAIDZ3...
