    nvme adapter with hp ex900 ssd pci-e nvme

    That's because they are in use by ZFS with their partition names instead of the label names. That's a safety mechanism to keep you from writing data from two places at once. When you remove the bare partitions from the zpool, the label names will reappear.

    nvme adapter with hp ex900 ssd pci-e nvme

    Ok, thanks! In my opinion, you're not doing anything wrong at all, it's quite clearly a bug that should be reported and fixed.

    nvme adapter with hp ex900 ssd pci-e nvme

    Heya! After reading the thread from the beginning, I don't understand what it is you want cmiu147 ? Bugs aside, you've demonstrated that you are able to start the system with and without cache drives. Do you want help confirming there is indeed a bug and not just you "holding it wrong"...

    Shell Fast and easy delete of partition and filesystem data

    Thank you! Your addition limited the execution to only one disk at a time, which is understandable, but I have had to clean drives in bigger chassis, like 24 drives and up, and in those cases, just seeing the drives blink one after another is so satisfying, it's like the closest to storage pr0n...

    ZFS Update: HDD went offline while resilvering is in progress || Is this a valid & up2date guide for replacing existing disks with larger disks?

    I would be very cautious with how to proceed at this point, since the output suggests something confusing in the 'zpool status' output. As I understand it, you have a raidz1 VDEV that you were already resilvering a disk when another one dropped, which to me would suggest a double fault = pool...

    Other SAS Multipath problem

    It's at least good you've pinpointed the issue, something that makes problem reporting easier. Although it does nothing to help you right now, please report it, so that it may get fixed in the future!

    Solved To compress or not to compress a virtual disk?

    Yes, but ZFS doesn't compress "files", it works in 128k recordsizes, that gets compressed.

    Solved To compress or not to compress a virtual disk?

    I have never observed any issues with fixed size disks together with lz4-compression, since it tests whether or not the data is "worth" trying to compress. I do know however, that thin provisioned disks can be problematic, where there have been issues in QEMU/KVM where the guest is writing data...

    Nice digging! Hope it works out for you!

    Other SAS Multipath problem

    I just asked to get the obvious out of the way. I have managed to get multipathing working with HBA in IT mode, with another card, using a different driver (mps), so there may be an issue with that model's driver you are facing?

    Solved To compress or not to compress a virtual disk?

    I have used a FreeBSD server with ZFS exporting NFS to a VMware cluster and have compared no compression vs. 'lz4', where the latter kicked the formers ass, big time, measuring with 'bonnie++' from inside a guest running on disks coming from that NAS, to put it differently :) Sadly, I have...

    Other SAS Multipath problem

    Just out of curiosity, the HDDs (SEAGATE ST6000NM34), are they NL-SAS or SATA?

    Solved To compress or not to compress a virtual disk?

    It may very well come at severe performance costs, depending on which compression algorithm you choose! For example if you choose 'compress=gzip9', well, it's going to suck, big time. But, if you choose 'lz4' instead, you may actually get better performance than without, since the host system...

    FreeBSD or FreeNAS

    OK, so obviously, I won't go into FreeNAS stuff, you'll have to ask on their forums for that, but I will answer- in general- how a NFS mount is made, from a Linux or BSD system. You have made an 'export' in FreeNAS, you specify in it 'who' should be able to access it and with what privilege...

    FreeBSD or FreeNAS

    It's very unclear what it is you're actually after but the closest thing that came to my mind was Cockpit. Sadly, linux only. All other solutions are geared towards a specific goal, like network administration with pfSense or OPNsense. The one general operating system admin utility I've found...

    How to install nosh init system on FreeBSD?

    FWIW, I have read the thread from start to finish and although mostly off topic (how to install nosh), I think that this discussion is definitely worth having, as all other possible enhancements to our favorite operating system! But the discussion on replacing or adding a new service manager...

    Performing an unlimited amount of major version upgrades without lifting a finger

    I have always heard how rock solid FreeBSD is as an operating system and if you only have one or two machines, it's alright, you know, no larger issues. freebsd-update isn't great but it's not terrible either, although it's biggest flaw is that it can't really run unmanaged. It stops and asks...

    Puppet and Foreman on top of Apache/Passenger

    I´ve recently learned something new about Foreman that I thought I should share, about how poorly it handles a lot of network interfaces: General question about RAM usage TLDR; If you have servers with lots of network interfaces, you have to make Foreman ignore them or else it will explode! :)...
