    Installing multipath-tools-boot for iSCSI?

    This package is necessary to prevent race condition issues at boot; what could happen without it is that VGs get trapped ahead of multipath by the operating system. If you dont have any entries in fstab for your iscsi mounts you dont need it. edit- to clarify, if you're not issuing iscsi...

    Proxmox - best practice to handle (USB) drives

    As long as your PVE box sees the drives (eg, /dev/sdb and /dev/sdc) you can do whatever you want insofar as deployment. You can make them individual VGs, or Single VG on both, or as a zpool, btrfs mirror, or passthrough to guest if you really want OMV. Understand that USB as a disk transport...

    Recover broken Ceph config possible?

    well since the cluster is still up, not all is lost (or at least there is still a chance of recovery.) start with logging into a node containing a working monitor: ceph config dump | tee -a /etc/pve/ceph.conf.rebuild alternatively, if it doesnt work: ceph config show-with-defaults...

    Hardware interface packages best practices

    I'd say that the question is too broad for a reasonable answer; most "software" doesnt care about direct access to hardware. application that need DO need access (eg, GPU) have these methods to accomplish: 1. for exclusive access, a gpu can be passed directly to a guest 2. for shared access, it...

    Mellanox ConnectX-3 & Proxmox 9.1

    1. try proxmox-kernel 2. says who? while the DRIVERS arent provided in the package, mst should work just fine. if it doesnt, you can always uninstall :) 3. that is one way; another would be to make a persistent live usb so you dont have to mess with your install at all.

    Site to Site VM replication

    Site to Site replication can be done to some extent with PDM. third party derived solutions also exist (Veeam, Pegaprox) as well as creative use of PBS. ZFS replication can be used if the sites are single node.

    Shared Remote ZFS Storage

    Ah. this is a sore point for me. the ONUS of decisionmaking is on the purchaser. If the purchaser doesn't understand what he is buying (be it for any reason short of outright fraud) then the fault lies there too; NO technology is without edge cases, and 99.999% uptime still means over 5 minutes...

    CephFS "Block Size"?

    The default stripe_unit size for ceph is 4M, but you may not want to raise that (and maybe even shrink it instead.) the stripe size is a maximum "file chunk" limit for a cephfs object (file). if a file is larger than the stripe size, the next portion of the file is written to A DIFFERENT PG...

    Shared Remote ZFS Storage

    I think I understand your point, but I dont subscribe to the viewpoint that "if I can do it myself there is no justification for someone else to get paid." There is nothing wrong, in my view, for a Nexenta or truenas to use ZFS internally; zfs is tried and true and works well. When you buy a...

    Shared Remote ZFS Storage

    I am really curious about this. Can you point to an "it" a specific vendor does that is not a good idea in your view? more pointedly- what would be an example of "shady stuff?" Interesting. I wasnt even aware that such solutions exist. would you be so kind as to point me to a vendor that...

    W11 Pro license and VM migration

    So... you're both kinda right and kinda wrong. It depends on the TYPE of license and how you bought it. RETAIL licenses are not tied to an underlying Windows server license, and therefore can be moved with the VM. OEM licenses ARE tied to an underlying Windows server. VL licenses are.... maybe...

    Mellanox ConnectX-3 & Proxmox 9.1

    Since mst 4.22 seems to be broken on 6.17, you have a few alternatives: 1. install an older kernel. 6.14 and 6.11 are both available. 6.8 is too I think. 2. use a newer version of mst. The most current version is 4.34.1-10 3. boot from a thumbdrive with a linux livecd. Once you set the...
