    NVME SSD durability under Proxmox

    Hi, I'm very satisfied with the SN850x, definitely a good value. But it's probably not the only one. Check around, check comparisons online in video or texts... SN850x 4TB is 4GB of DRAM (for read cache), pSLC for write cache (volume is usually not announed), and TLC based. It also exists in...

    Slow 10Gb network

    MTU won't limit you that bad. I even abandonned playing with that, and stick to the default 1500b because it generated terrible situations, difficult to debug, for close to no benefit. However, as propose @jamiemoles , definitely check your network interfaces, and make sure the "Errors"...

    NVME SSD durability under Proxmox

    Hi, You have to look at the endurance specs of your SSDs, especially DWPD ((full) Disk (capacity) Write per day) or the TBW (TerraBytes Written). For low budget, I prefered to take only 1 SSD for everything, but opted to a quite high end home one with 2400 TBW ...

    What is the best way to mount a CephFS inside LXC

    Seems a recurring problem, and did not find helpful solution so far. There are hundreds of cases you might need to mount CephFS inside your LXCs. In my case, I need to store PostgreSQL WAL archives for PITR. Performances are not important. I have a 3 nodes PVE cluster. I tested : Standard...

    Timeout loading datastore content

    Hi, Same problem : I have an (rclone encrypted) datastore on a S3 cloud storage. The dumps are working, but I have a timeout when listing the backups on that datastore through the GUI. The only way is to list them via command-line ls on the host. The initial listing can take up to a minute, and...

    [Fixed][ceph][mgr][snap_schedule] : sqlite3.OperationalError: unable to open database file

    On every reboot or power loss, my ceph managers are crashing, and the cephfs snap_schedule is not working since 2023-02-05-18. The ceph mgr starts anyway, and generates a crash report turning the ceph cluster in HEALTH_WARN status. I have the issue on every node (3 nodes cluster). Probably since...

    [pve 7.3-4] invalid privilege 'Sys.audit' (500)

    Thanks for the quick reply Fiona, While waiting for the bugfix in 7.3-5, the workaround is easy: use the root user with PAM authentication (maybe other user with PAM auth ?) use the command line ceph osd status to get the osd id, then use systemctl. i.e. for osd 0: systemctl restart ceph-osd@0

    Hi, I'm getting the invalid privilege 'Sys.audit' (500) popup error message when I want to Stop an OSD with a "Proxmox VE authentication server" user that has Administrator as only role. The problem does not show when using the root user with PAM authentication What is strange, is that...

    cephfs mount inside LXC

    Did you find any solution ? Using mount point (mp0) (only via command-line), does the job. BUT, it's then impossible to migrate the VM to another host. Using the kernel driver or the fuse driver both fails because of missing modules... 1. Did you find any solution to mount a cephfs inside an...

    [Solved] HTML table broken for vzdump backup status email reports (PVE 7.2-14)

    Hi, All the HTML is broken on vzdump backup reports: All VMs appears under the same vmid. Time, size, and filename columns are missing (only headers). I did cut the screenshot in 3 to remove all useless parts, but all appear under the single vmid 120. This seems like a backup log parsing issue...

    What is the "Regenerate Image" in Cloud-Init section ?

    I use cloud-init image, so I have the Cloud-Init section. When I change a setting, it's just changing it after reboot, as expected. So I feel the Cloud-Init cdrom image is automatically rebuild on change, and I never needed this "Regenerate Image" button. "Regenerate Image" is missing from...
