    Size mismatch VM windows with Proxmox ZFS?

    Disclaimer: I am not a proxmox user, but am well familiar with KVM and have used ZFS for many years. I am curious if you figure out a way to do this. What I've seen is that Windows will not unmap blocks in a way that ZFS sees as "freed" when stored as image files (e.g. qcow2) in a zfs...

    HGST: Unknown smart status after low level format

    It says unknown (I'm pretty sure) because there are no thresholds detected. Did this drive ever work in your possession? Try in a linux machine and use gdisk?

    nvme enabler cable?

    Yeah if you have bifurcation support on your board, just jump on the linkreal. I have a linkreal pci-e switch card with 4x 8643 on my ryzen system (I don't have bifurcation support) and it works great.

    nvme enabler cable?

    they're expensive and not worth it at all. I couldn't get more than 600-900MB/s on 2TB Intel P3500 drives. I was using a Lenovo 530-8i erased and put on stock Broadcom firmware (equivalent to 9400-8i). Also, the smart data refused to pass through. My advice is walk away and go buy a proper quad...

    Asus Strix X399-E U.2 (sff-8639) to SATA using mini HD SAS to SATA

    Highly doubtful. I would point you towards reading the manual for the board to confirm, but that is almost assuredly only for carrying PCI express.

    Ubuntu Server & L2ARC on Same Drives

    What use case are you trying to target here? Storing your movies? Multiple people accessing documents/roaming profiles? Virtual machine storage? A lot of usages have no benefit to L2ARC and will just wear your SSDs out. Is this for a hobby/home use or is this for something important/production use?

    ZFS/By-ID = wwn??

    I work with ZFS day in and day out for my day job and use it at home personally. think of wwn like a mac address (it basically is the equivalent in storage land). I've never seen issues using wwn. I would leave it as is. You can create a pool however you want and then re-import it using a...

    Need recommendation for 16x nvme JBOD (for zfs)

    look up Ceacent and LinkReal on Aliexpress. Example here 39.0US $ |ANU04PE16 NVMe Controller SFF8643 SFF8639 4 port PCIe3.0 X16 SSD Exp Riser (not with cables,not support LSI 8643*2 to 8639*2 )|Add On Cards| - AliExpress I'm assuming ROME8-2T has bifurcation support. You will need to turn...

    Experiences with NetApp DS4243

    I have one DS4243. The first thing I did was put in a pair of Dell Compellent 6Gbps controllers (as you've referenced) that use normal SFF-8088. Sometimes these can be found cheap. Example here Genuine Dell Compellent HB-SBB2-E601-COMP 0952913-07 6GB SAS EBOD Controller OEM 787421252224 | eBay...

    Need some basic Linux help

    Just add it in /etc/fstab is the short answer and probably the right way to go. There should be plenty of examples for this. You should be able to use documentation not specific to mint since fstab is a generic part of Linux for mounting filesystems in a pre-defined way.

    Multi-NVMe (m.2, u.2) adapters that do not require bifurcation

    Honestly, I think your money is much better spent getting a SAS-2 controller like LSI 9211-8i, Dell H310, or IBM H1110. You should be able to get a card for $20 and maybe another $10 for wiring to get 6Gbps speeds. I think NVMe generally speaking would be a waste (ignoring the money factor)...

    Any advantage to nvme hba other than saving pcie slots?

    I have a pair of Lenovo 530-8i flashed to standard 9400-8i firmware. The NVMe performance was garbage (800MB/s) and it required the proprietary cable from Avago. My advice is save your money and get something from this list I posted. These are simple PCIe cards with PCIe switches. No...

    AOC-SHG3-4M2P

    If you don't get any answers from someone who has one, here are my thoughts. Your logic behind heatsink = pcie switch is what I'm thinking as well. If you're looking to already mix hardware up in terms of vendors, I'd probably suggest getting one of the ones from aliexpress that I've outlined...

    Seeking SAS2 raid card recommendation

    Just get a Dell H310. It will take care of Raid 0 and Raid 1 easily at full speed. If you ever decide to switch to software defined storage, you can use the same controller. $30
