    [SOLVED] vzdump failure with stopped LXC: .zfs/shares EOPNOTSUPP: Operation not supported on transport endpoint

    Good day, Busy cleaning up LXCs that I had shutdown, but seems to keep getting this error with the methods SNAPSHOT & STOPPED Backup works fine after starting the LXC, but want to backup the "downed" LXCs with the troubles/issues that could happen with starting these (if any)

    [SOLVED] Hypervisor and all VMs hungs during high IO loads

    That is the reason to force the arc smaller, perhaps even drop caches (sending 3 to vm.drop_caches) just before the expected RAM pressures. I've seen similar with a system that had a very high number of files (LXC) that caused ARC pressure problems during backups, as the ARC was under pressure...

    Forwarding Proxmox logs to Graylog

    It seems to be possible to get something more automated than manual copy-pasting. Still, if it's there, then it's queriable

    Forwarding Proxmox logs to Graylog

    you tag the filename_upid and a special tag like this_is_upid_detail, and then when you get a UPID in the mainlog, you can do a query on the this_is_upid_detail with filename_upid == UPID to fetch the relevant details. incron/FAM/etc.[1] is adding a tad more... fragile complexity, to the...

    [SOLVED] Hypervisor and all VMs hungs during high IO loads

    perhaps should've limited ZFS's ARC sizing?

    Forwarding Proxmox logs to Graylog

    I did :) Bit.. of a bigger challenge when you want to stream the logs to a central logger/store (Like Loki / ElasticSearch) using a quite static tool (like Promtail / Fluentd / Graylog )

    Forwarding Proxmox logs to Graylog

    My question, as I'm busy with a central logging project on multiple ProxMox clusters to log to Loki via Promtail: is there a hook script of sorts to be able to know when the next file is created/closed/etc.? A bit counter productive to scan the directory every couple of minutes, and then to...

    Promtail (to Loki) for task logs?

    One of the questions that arise with this: is there a hook that would be called at the end of tasks? Then it'll be an easy method to use that to send the task output to the central logger

    Promtail (to Loki) for task logs?

    Good day, Anybody done promtail configs for getting task logs into Loki/etc. ?

    Advice for memory optimisation / overcommit

    The same way as ISPs oversell bandwidth by playing a numbers game ie. expecting that, on average, users will not use more than 50% of RAM, thus 100 x 2G VPS's expecting to not use more than 100*2*0.5GB of RAM. Some even enforce (inside VMs) echo 3 > /proc/sys/vm/drop_caches and others have...

    Synchronization over latency links - parallel fetches?

    That is/has been the "solution" to assist in catching up, but it becomes.... tedious to load/create them all. But then it gets stuck with the single big DB which is then single synchronous thread.

    systemtap compatible kernels?

    I've got a situation where I need to run something like systemtap to track especially DNS requests. Found this solution https://serverfault.com/questions/192893/how-i-can-identify-which-process-is-making-udp-traffic-on-linux/192920#192920 that would've be a "perfect" solution, but PVE kernels...

    Synchronization over latency links - parallel fetches?

    I have a case where the latency for a cross continent synchronization, is being slowed down by the "small" requests from the pulling PBS. If I start up multiple synchronization jobs for multiple backups groups, I do get the full (expected) bandwidth, but when it's "stuck" on a single group's...

    Secrets vault or similar to Instance metadata and user data (AWS IMDSv1/2)

    I'm starting to hit my head into the needs for something similar to AWS's IMDS (using IPs fd00:ec2::254 & 169.254.169.254) with something connected to a Vault (ala HAshiCorp's Vault) for secrets and automated secret sharing/etc. without the secrets/passwords being unencrypted in the VM/LXC...

    Machines lose network connectivity after host network restart

    One reason: OpenVSwitch's deamon needs to restart, and that kills the bridge during updates/upgrades of the `openvswitch-switch` package

    FAI(me) .ISO for guests - with cloud-init suport?

    Good day I've stumbled on FAIme https://fai-project.org/FAIme/ which creates a "nice" ISO installer that mostly just work... except for the requirement/need of DHCP (not an option at present, unless you could advise a ISC KEA option/replacement with cost effective (for me) static host API...

    VM network crash after openvswitch-switch upgrade

    well... that replug via GUI is just.... not feasible when you have tens of VMs/LXCs to do. Where is that `ifreload` documented? I wished it was something part of the upgrade documentation/etc. or at least triggered with a warning whenever OpenVSwitch is involved
