    Proxmox version comparison for compatibility

    Guess you're right, the server is a new install, so there may be no relevant updates at the moment, but it's a matter of time and so I'll have to enable no-subscription repository, even if it is a production environment. Well, that way I'll be sure that both test and production environment will...

    Proxmox version comparison for compatibility

    Thank you for your reply. Well, pve-1 is my production environment, the server were I'll be putting the VM machines to good use and I want to have the best stability possible. I don't have a subscription and assuming the no-subscription may bring some issues, I guess I'm being too cautious...

    Proxmox version comparison for compatibility

    Hi, I need your opinion to understanding the compatibility between two proxmox machine versions, or how can I check for any possible compatibility issues. I have the following machines: pve-0: A proxmox originally installed with 6.0-4 ISO, then upgraded a few days ago to version 7.3-6...

    Best approach for a TrueNAS VM

    Oh, ok ... that changes the game around. I'll take a better look at that, but suddenly the PCI passthrough starts looking as a better approach... Thanks.

    Best approach for a TrueNAS VM

    Thank you for your quick reply. With disk passthrough I was thinking that I could just remove the disks and connect to another PC in case of such need, and would be able to re-mount the storage as they are all part of the same ZFS pool. But you're right, having them set as virtual disks, I...

    Best approach for a TrueNAS VM

    Hi, I'm thinking about setting a truenas VM on a proxmox server and scenarios which I can choose for that job. On proxmox installation I have a ZFS raid10 pool for VM storage. I would create a VM for the truenas, but what would be the best option for the truenas storage? Scenario #1: One...

    Setting network bond for VMs only

    A few more tests ahead, I tried to change the bond mode from balance-rr to balance-alb, and ended up with the following config on /etc/network/interfaces: auto lo iface lo inet loopback iface enp65s0 inet manual auto eno1 iface eno1 inet manual auto eno2 iface eno2 inet manual auto eno3...

    Setting network bond for VMs only

    Hi, I'm testing some network settings on a proxmox server (pve 7.3-3) and I'm having trouble setting up a network bond to work. On this server, I have a network card with 4 ports: eno1, eno2, eno3 and eno4 I added another network card that would be used for the management console only...

    vzdump : Unknown option: –dumpdir

    Wow! That was driving me crazy. After all the checks, the terminal showing the same visual representation of those distinct chars, only with a more close look I would find the problem after posting the message here. That was clearly a copy-paste from the documentation I was checking online. :)...

    vzdump : Unknown option: –dumpdir

    Hi, I'm trying to make a full backup of a VM to an usb drive, but somehow I'm getting an unexpected error about the parameters being used. So I've started by mounting the usb drive, setting an ext4 fs, mount it to /mnt/usb and creating the folder /mnt/usb/vm.backups where I'll be storing the...

    Proxmox with HDD SAS disks

    Ah, I just saw what you are saying about ashift setting per vdev, also the openzfs#566 commit allowed the setting to be included in add/attach/replace commands: zpool add -o ashift=12 tank disk1 zpool attach -o ashift=12 tank disk1 disk2 zpool replace -o ashift=12 tank disk1 disk2 Which...

    Proxmox with HDD SAS disks

    Reality check: Whenever I feel I'm getting more into it, something new just pops up reminding me that I still have a long road ahead... :) But hey, that's the fun part of it, and that's what makes me keep coming back... From what I've read in a few minutes about ZFS special devices, it really...

    Proxmox with HDD SAS disks

    So you only have a single zpool and use the SSDs as cache? But you still had to choose what ashift to use right? You made any testing with ashift=9 vs ashift=12, or in your case you may be switching latter on for 4k disks and opted for ashift=12 right from the start? Thanks.

    Proxmox with HDD SAS disks

    Thank you for that detailed answer. Still struggling to understand as much as I can... As for the disk info, I've run an fdisk -l command and retrieved this results on the HP 146Gb and HGST 600gb disks: Disk /dev/sdd: 136.73 GiB, 146815737856 bytes, 286749488 sectors Disk model: EH0146FARWD...

    Proxmox with HDD SAS disks

    Thank you for your tip, I'll check them out to see what they are reporting. I'm aware that ashift can't be changed latter on, and if I replace one disk with a 4k sector size it will have a negative impact with some excessive writes, that's one of the reasons I read some places that nowadays it...

    Proxmox with HDD SAS disks

    Well, I can put a pair of HP EH0146FARWD 146GB 2.5" SAS 15K and set them on Raid1 for proxmox OS. That would give me more reliability on the OS. Yes, going for SSDs would give me a lower power consumption and greater performance, even on SATA connectors. The thing is I wanted to keep costs as...

    Proxmox with HDD SAS disks

    Hi, I'm currently starting the process of creating 2 proxmox servers for very similar objectives, both with very similar specs. The main hardware specs are: - 2x Xeon E5-2695V2 processors; - 128Gb PC3L 12800R RAM; - SAS Controllers in HBA IT mode. The usage will be to install a couple of VM...

    Will a Dell PowerEdge R720 be up to the task?

    Sorry to revive this thread, but I'm looking into a possible upgrade, and going for PC3L 12800R modules. I'm not familiar with those types, maybe someone can help me understand: The PC3L means it is an LRDIMM and thus it will not have the rank rule when adding more memory modules? Or it simply...

    Samsung SSDs a right ashift size for ZFS pool?

    I noticed that low value, and some others like the total gb writes. It's a bit worrying if one is able to change smart data, from that point it means that no one can trust that info when buying disks that are not new... But then again, other indicators like "Reallocated_Sector_Ct" or...

    Samsung SSDs a right ashift size for ZFS pool?

    Hi, Well, I followed your advices and I will replace the EVO SSDs with a pair of PM883 SSD disks. I prefer to be on the safe side, even though budget doesn't always help. Testing the 2 disks I now have, I found them to be in very good shape. Basically they seem like new drives to me, am I...
