    alexskysilk replied to the thread Ceph performance seems too slow.
    What you're describing is a mesh network. for the purposes of the conversation, this is the same as having a single active link on each node for both public and private networking. so you're sharing the IO for any PG between the client and disk...

    alexskysilk replied to the thread Ceph performance seems too slow.
    you DO understand that your "speed" can't be faster than the transport. and if you are using the same interface for both public and private traffic that essentially caps your performance at 5gbit/s. this is your drives' observed latency, and has...

    That doesnt apply to ANY software applicable to an internet connected device. Security vulnerabilities are constantly identified, exploited, and patched in a never ending cat and mouse game. Moreover, a hypervisor is complex and problems are...

    yes. see https://pve.proxmox.com/wiki/User_Management#pveum_permission_management you will not be DENIED support, but the first answer to any issue would be "make all cluster members the same version." This isnt unique to Nutanix or Proxmox; its...

    While I dont see what firmware is on your controller, the host bios gives me an idea of how long it's been since you've updated it; time to get the latest SPP.

    Thats the problem though isnt it; "linux" wont see the drive until you do.

    I just noticed this little bit for the drive in slot 0 you will need to reformat this disk before you can use it. its possible that the controller firmware will not let you map it until you do; so you will need to plug the drive into a real HBA...

    what about the rest of the devices? if none worked, time to see to firmware updates (run lifecycle) and/or call dell support.

    you missed a step.

    if you intend to use this in production, I suggest you spend some time familiarizing yourself with the tool (megacli.) there are many resources online for that. To answer your specific question, megacli expects enclosure:slot, so your command...

    that step might not be necessary for your specific controller; PERC cards can serve raid and jbod simultaneously.

    ahh right. ncurses5 is not available to trixie- but the good news is that we dont actually NEED it. we just need to fool the system into thinking we already have it, like so: apt install -y libncurses6 ln -s...

    Luckily for you, you dont have to be dependent on the firmware controls. once booted to PVE, install megacli/perccli. from there, you can /path/to/MegaCli64 -pdlist -a0 /path/to/MegaCli64 -AdpSetProp -EnableJBOD 1 -a0 /path/to/MegaCli64...

    alexskysilk replied to the thread OSD errors.
    What you're seeing isnt actually errors. It is, however, an indication of OSD resource starvation; if osd 4, 6 and 8 are all on the same host, check overall host load, and might need to make some adjustments hardware-wise. Alternatively, you can...

    SAS3 drives have a "SAS Power Disable" pin which does not exist on SAS2 or earlier backplanes. How are you attaching the disk to the host bus adapter? what kind of backplane does your server have?

    alexskysilk replied to the thread Recovery: OS Drive Died and Now I'm Trying to Recover My VMs.
    if you can see the location on the filesystem, you can use this to create matching fstab /etc/pve/storage.cfg entries in your new pve installation. You will need to create the configuration files for your resources manually, however- effectively...

    vmbr= linux bridge. its not a bond. think of it as a switch. you have one bond defined, bond0, and it is using enp1s0f0 and enp1s0f1 as its captive interfaces (slaves.) if you want to use eno1 and eno2 in a bond, then that's what you should...

    you have vmbr0 using two uplinks directly and bridge stp turned off. Either turn it on, make sure the uplinks do NOT go to the same switch fabric, or make sure STP is turned on upstream from you. not really sure what you're after- if you can...

    See, I was right there with you till the word "drastically." Especially when that statement preceding was Please share your statistics backing "your rule." the word drastically has pretty substantial implications, and if the whole basis for...

    Not sure where the connection between PLP and user scripts lie. wear out on any SSD made in the last 10 years is such a remote concern as to not warrant any thought at all. I bet you dont have a single SSD that is ANYWHERE CLOSE to wearout- I...
