    CEPH - NVME

    Hello, Consumer grade SSD's (including NVMes) performance usually drops in a considerable way once they fill their cache. Once you are in this state latency will also go up. Ceph does more IO operations than other filesystems like ext4 and it is also more sensitive to latency, so you are more...

    Extremely bad network speed between PVE nodes

    Hi, I just discovered a rather interesting fact - it seems that the issue only persists, once a Windows VM is involved. If i use iPerf3 on Ubuntu VMs that resides on different PVE nodes, i get a full gig link - but on Windows i get limited. And yes - the VirtIO driver is installed :)...

    Extremely bad network speed between PVE nodes

    Most consumer grade disks are notorious for becoming excruciatingly slow after they fill their cache, by doing a 2gb benchmark you are not going to hit this limit. On the other hand, day to day operations on VMs will probably fill the cache of a consumer SSD/NVMe rather quickly. This is...

    Production server

    Why disable service? They work on the disk system and can reduce ssd life?

    Production server

    I may be doing this all wrong, but I would go with ZFS, disable disable corosync, pve-ha-crm, and pve-ha-lrm, and then keep an eye on the health of your drives. I am using a ZFS mirror pool for two NVMe drives for my VM storage and a separate ZFS mirror pool for two SATA SSD drives for my OS...

    Just checking before buying my new machine

    A short guideline: - SMR HDDs -> avoid at all cost - CMR HDDs -> only useful as additional cheap cold storage - QLC SSDs -> avoid whenever possible - TLC conumer SSDs -> might be fine for a low demanding small consumer grade homeserver with ext4/LVM - Enterprise/Datacenter SSD with power-loss...

    Proxmox Freezing/Crashing During Backup on Dell PowerEdge R820

    Hello Proxmox Community, I'm currently running a Proxmox VE setup on a Dell PowerEdge R820 with the following specifications: CPU: 4x Intel(R) Xeon(R) CPU E5-4650 0 @ 2.70GHz RAID Controller: PERC H710 Adapter Memory: 64GB RAM Storage: 3x Dell Enterprise-grade SAS 900GB hard disks 1x Samsung...

    Storage recommendations for home workload?

    Aside from endurance, I don't see how it's worth it to invest in an enterprise SSD for a very light workload like mine (I'm still learning all these technologies after all). Also, the enterprise SSDs I can buy in my region (D3-S4510, D3-S4520, PM893, Micron 5400 Pro, D3-S4610) perform about the...

    RAID problem.

    ...The SSDs firmware doesn't know about your UPS, so it won't cache data that shouldn't be lost under no circumstances. Here a HW raid with BBU + cache comes handy, as it can cache those sync writes before they hit the disks, so sync writing to HDDs or consumer grade SSDs should be magnitudes...

    Newbie questions

    No. If it doesn't got power-loss protection and no 1+ DWPD thats not a enteprise disk. BX500 is terrible QLC consumer grade SSD and more usable MX500 is TLC consumer grade SSD. BX500 would be terrible with ZFS and MX500 are debatable. Some people use them and think they are fine, some complain...

    [SOLVED] Upload Iso-Dateien

    PVE schreibt dir viele GBs am Tag an Konfigdateien/Logs/Metrics auf die Systemdisk. USB-Stick/SATA-DOM/SD-Karte geht schon, da brauchst du dann aber entsprechende Industrial/Datacenter Versionen die dank SLC/eMLC NAND das dann aushalten. Und ich vermute du willst keine 100+€ fur einen 16GB...

    Disk configuration recommendations please

    You could run pveperf /path/to/your/NvmeMirrorsMountpoint to see how well those NVMe SSDs perform. For comparison, this is a SATA SSD ZFS mirror: FSYNCS/SECOND: 5048.26

    Cluster getting really ssssllllloooooowwwwww :-(((((((((((((((((((((((((

    Yes, got me :) these are slow/standard (500MB/s) consumer grade SSDs (the NVMEs were consumer grade as well, albeit faster). Okay, but say I buy Samsung OEM Datacenter SSD PM893 / Enterprise SSD PM893 They are not (or only minimally) faster at 550 MB/s. So what kind of load does Ceph...

    Openning Proxmox to the WEB for Management and its VMs. Multiple questions for final networking-securing-backup-imaging of Proxmox and its VMs.

    low energy HW suggestions

    If you ever had a bad RAM module you won't want non-ECC again. Here 3 DIMMs failed, one after another and that corrupted hundred of GBs of data on my TrueNAS over a few weeks. If you don't keep your backups for months, you are screwed, as your backups will also contain the corrupted data. Would...

    Virtuelle Disks unterschiedlich häufig sichern

    Aus der Ceph mailing list (Quelle): Und hier noch via StackExchange (Quelle): Habe dazu früher auch schon immer in Verbindung mit Ceph gelesen, dass man von SSDs ohne PLP die Finger lassen soll und HDDs nur zusammen mit WAL/DB auf NVMe (mit PLP) nutzen soll aufgrund der Thematik. Unsere...

    [SOLVED] Proxmox VE 7.4-13 High I/O Delay Only With Windows 11 VMs

    At this point I'm desperate to get this working correctly so I'm willing to purchase new storage devices if it would eliminate this issue permanently. I assume this is a really bad fsync rate? root@proxmox2:~# pveperf CPU BOGOMIPS: 79872.00 REGEX/SECOND: 7026403 HD SIZE...

    Disk for os?

    Hello!!! how are you? I hope you all are okay. I have a mini pc in which I want to install pbs. but enterprice sata ssd drives cannot be placed in the mini pc. It only accepts m2 disks. pbs wears out ssds as much as proxmox does? Or can I install the OS on a consumer grade nvme m2...

    [SOLVED] Proxmox VE 7.4-13 High I/O Delay Only With Windows 11 VMs

    any consumer drive without supercapacitor (plp protection) will be slow. (because the supercapacitor is like a battery, and write/fsync are keeped in ssd memory). so both m2 and sata ;) (and I don't think they are any m2 format with plp, as it's too small physically) The problem with...
