When running pmg7to8 we see: WARN: systemd-timesyncd is not the best choice for time-keeping on servers, due to only applying updates on boot. It's recommended to use one of: * chrony * ntpsec * openntpd as this is mentioned in pve too, we checked it (all our servers running...

I would not recommend pve as desktop virtualization. that's what you are describing. pve's focus is on datacenter virtualization / private cloud I'd simply use KVM e.g. virt-manager. probably virtualbox.

clonezilla multicast setups ftw :) (massiv parallel setups of 50 pce cpe per run, back in the days....)

you can (I guess :)), but you should not (definitly). reducing fs is not that easy though. if you want the system ssd for ceph you are better off bying a small new ssd for the system and use the former system ssd as osd. if you do your system just for testing and fun, do it and try it. that's...

go to datacenter, define a local storage with your zfs pool, create a vm with a disk on this storage. install nfs in this vm. any other vm can use this nfs export. the nfs server is just one of many vms

if you really want to share a local mountpoint by nfs i'd go for the nfs server installed on localhost too. apt install nfs-kernel-server edit /etc/exports and you are in. but why not just use the zfs as proxmox storage and create a guest (nfs server) using it (storing the virtual disks...

afair there is a LSI cli tool to query status and configure the controller. Either you just run a simple cronjob kind of if-then-alert or you integrate it in an existing monitoring solution like nagios, zabbix and so on

die option per user / per domain zu disablen wären auch unabhängig von Ticket systems wünschenswert

journald I guess. rsyslogd is legacy in current debian

wenn du physischen Zugriff hast mit Hilfe von mii-tool (an ab stecken) und wenn nicht sagt dir der switch welche mac am anderen Ende angesteckt ist. die mac nic zuordnung kannst du zb mit ip address show (ip a genúgt) ansehen.

ah, ic... will check this. thank you

Hi thought so, thx. ("no compatibility guarantee for clusters with v5.x and v7.x nodes" <- good point) it's not my first dist-upgrade of clusters, but this one is a very time- (and coordination-) consuming 'cause not all VMs can live-migrate (5x doesnt allow live-migration with local storage...

Hi I have to dist-upgrade a cluster currently running 5.x (already corosync-3). your recommendations are welcome: can I dare to dist-upgrade each host 5->6->7 (not 5->7 but 2 dist-upgrades while the rest of the cluster ist still 5.x)? or should I better go the slow way and dist-up to 6 the...

this depends on the cabling of controller/motherboard and backplane. if you assume slot 1 is most up/left 9f your slots. thats ok. mostly. but what is slot 2? the disk right of it or below it? had both. and I had machines where slot 1 is the most left/down(bottom) slot. so no pci or any other...

Beides. Einen VLAN-Switch bekommst du fuer ein paar Euro (kurz bei geizhals reingeschaut, ab 20 EUR 5 ports). Ich würde einen gebrauchten Server in Betracht ziehen (zb Intel XEON E3 oder E5) wenn er nicht durchlaufen muss/soll oder einen alten Laptop. Mein Test-Cluster besteht zb aus Dell...

ich würde mehr wert auf möglichst viel ram und schnelle cpu legen. das ist imo wichtiger um wirklich testen zu können. mit vlans kannst du im testbetrieb alles an einer nic machen, zuwenig ram oder langsame cpu behindern aber wirklich.

normally systemd should recognize remote mounts automatically, but you can try _netdev as mount option in fstab. this tells systemd to mount after network is online.

I dont know if zfsunlock has a feature to do that, but on the shell you can accomplish this with "expect" regards Peter

we too would appreciate neutral language

thx. the destination is a fully licenced cluster anyway. the open question was "when" to do the licensing of the new cluster hosts (that will stay while the oldest ones will drop out).
