    alexskysilk replied to the thread Curious about kernel updates.
    "kernel" being "out" doesnt mean anything directly to a distribution with a support policy. Instead, the maintainers of your linux distribution (in this case, ubuntu) will backport important changes that are deployed to downstream kernels...

    alexskysilk replied to the thread Shared Remote ZFS Storage.
    I would retort with calling a solution shady because its imperfect to be an irrelevant argument to begin with. The difference between "first tier" and not ISNT that they are (perfect), its that they have the engineering capacity and support staff...

    alexskysilk replied to the thread Shared Remote ZFS Storage.
    There are vendors, and there are vendors. NetAPP is first tier. the fact that my wife's nephew put together a NAS using gum and bailing wire doesnt make him of the same caliber. As for trusing your data... on prem storage exists precisely so you...

    alexskysilk replied to the thread Proxmox roadmap - future direction of snapshot‑as‑volume‑chain.
    Not an endorsement since I have not used myself, but Starwind StarLVM (the substrate of Starwind VSAN) looks like it would do what you ask. https://www.starwindsoftware.com/starwind-virtual-san

    alexskysilk replied to the thread confused...CEPH delivering same performance on 100G as it did on 1G test.
    that explains your observed performance. LACP is your first choice. if thats not possible, use active-backup and MAKE SURE the switches have plenty of bandwidth interconnecting them. balance-xor sounds good on paper but not in practice. set...

    alexskysilk replied to the thread Is there a compatibility matrix for hardware?.
    sure. https://www.proxmox.com/en/services/support-services/support I dont see any issues. boot storage could pose some specific challenges depending on hba model, but solvable. see https://pve.proxmox.com/wiki/Storage. shouldnt pose any issue...

    alexskysilk replied to the thread Proxmox with ceph performance.
    network interface mtu mismatch would decimate percieved performance, but there are other possibilities. while I'm not volunteering to check for you, you might want to ceph config dump ceph config show osd.x --show-with-defaults and go over it...

    alexskysilk replied to the thread confused...CEPH delivering same performance on 100G as it did on 1G test.
    This doesnt result in any meaningful benefit vs just having the same address for public and private traffic. OP, if you have multiple switches, I would create laggs for public and private traffic- and make sure to cross physical nics (presuming...

    alexskysilk replied to the thread IBM Plugin.
    looking at the whitepaper, the author did much of the heavy lifting already. there's enough foundation for you to write the plugin. Having said that- making a supportable solution is still not a trivial task.

    alexskysilk replied to the thread Small Datacenter Setup - What is the maximum number of pve servers supported in a cluster.
    Read the link @bbgeek17 referenced. when you're done, you should have a realization that the problem you will run into isnt just how many NODES are in the cluster, but also how much virtual resources. PVE's solution for cluster metadata...

    alexskysilk replied to the thread Proxmox (as a company) - what the HELL are you doing? Kernel update to 7 broke networking IN A VM.
    running software at home and for production are two completely seperate skillsets, mindsets, and realms of responsibility. As others have pointed out, you opted to install an optional kernel, and got bit. it happens. if you did that on a...

    alexskysilk reacted to ness1602's post in the thread Proxmox (as a company) - what the HELL are you doing? Kernel update to 7 broke networking IN A VM with Like Like.
    7.0 is a test kernel,not an enterprise kernel atm, so if you are okay with breakages you use this kernel. If not, you usually pay for enterprise subscription. Why would you be angry on a company giving you a test repo?

    alexskysilk replied to the thread VM not booting up with LVM FC LUN storage.
    I forgot df so we know what /mnt/pve/pVE-ISO points to. it looks like you're only using one of your LUNs for virtual disk use; I only see two volume groups so its a wonder where it is assigned to. do NOT assign it to PVE-DS01 as it is a shared...

    alexskysilk replied to the thread Ceph with 2 Cluster Networks.
    Just be sure you do NOT mix other traffic along with these, most especially corosync. if you have more then 4 interfaces keep the other forms of traffic on different interfaces. If you dont- consider only using two interfaces for ceph and two...

    alexskysilk replied to the thread Ceph with 2 Cluster Networks.
    rather then quoting, I'll try to address all possible alternatives. ceph carries traffic on two seperate networks- public (host) and private (OSD-to-OSD.) Think of this as the host bus and disk bus on a RAID subsystem. While you can have both...

    alexskysilk replied to the thread new drive setup, considering RAIDZ1.
    up to you how you manage your models. in my experience, new models are released every week and I dont bother keeping the old ones. Feel free to keep your hoarded models on the zpool. its not like its getting any use ;)

    alexskysilk replied to the thread new drive setup, considering RAIDZ1.
    keep those on the nvme. they dont need any resilience, and you're likely to be replacing them quite often anyway.

    alexskysilk replied to the thread new drive setup, considering RAIDZ1.
    so yes :) l2arc almost never yields useful results. you're better off just using the drive seperately. More to the point- what is your usecase? in a homelab, its common that your bulk storage can be slow without any real impact. put your...

    alexskysilk replied to the thread IBM Plugin.
    IBM Storage arrays can be one of many different solutions/topologies. It would be useful to mention what model/topology product you're referring to. Having said that- it most likely is a block device so yes, lvm would still be necessary if you're...
