hi @guletz, thanks for the great response. I think we will extend the hosts with the M.2 card and remove the pressure :-)

hi, exactly that is what we are try to do. The only sad thing is, that we have to reinstall the hypervisor. On a different host I've choosen a 2 x raidz1 with stripping and it works well with the exact same hardware. But, one question: We have a single M.2 slot, does it make sense to use it as...

hi, problem is, that we have issues with the VMs and a lot of [Sun Oct 14 02:06:07 2018] NMI watchdog: BUG: soft lockup - CPU#3 stuck for 52s! [check_ .... nearly every day. Every check command, which needs to be executes produces the same messages. I think, it happens, while the underlaying...

hi, we've got notifications from our monitoring (Icinga2), which is a VM on a PVE 5.2 host, with WD RED(WDC WD10JFCX-68N6GN0) 6 x 1TB (2.5") as Raidz2, because of timeouts (check_icmp). After a longer investigation, we found out, that these alerts where false positives, because the monitoring...

Hello, I have to say sorry: The VMs had only in sum less than 1TB used for space. df -h had plenty of (4)TB free for usage, also RAM /tmp /run ... and some more I had a closer look ... nothing, also all snapshots (only two snapshots) where deleted .... nothing. But, this host was/is so...

hi, is it possible to create a pool out of 2 x Raidz-1. I assume, that the performance is quite better, than now for a raidz-2 out of 8 disks. Or can I install on a Raidz-1 and add a second Raidz-1 to the pool? cu denny

hi, now it happens again .. my MariaDB nodes was killed and on the Proxmox I have: icinga2[4025]: [2018-05-22 23:16:04 +0200] warning/PluginCheckTask: Check command for object 'qh-a07-pmox-06.inatec.com' (PID: -1, arguments: '/usr/lib/nagios/plugins/check_load' '-c' '8,6.4,4.8' '-w'...

hi, we have very strange behavior on one of our Proxmox 5.x . We had a very bad I/O performance with PVE 5.1 with 8 x 1TB WD Red in a Raidz-2 installation. We did an upgrade to the latest 5.2 and the bad performance has gone, but we had the very strange thing, that one of our VMs stopped. This...

Hallo Wolfgang, ich nutze Icinga2 welcher als Satellite arbeitet. Dieser führt unter anderem SNMP Checks aus. Icinga2 ist so konstruiert, dass wenn ein Check nicht in der Laufzeit n fertig wird, dann wird der Prozess schlicht abgebrochen (kill). Ich habe dieses Phänomen tatsächlich nur auf...

Hi, ich klinke mich hier auch mal mit ein. Wir haben auch einen Server: Proxmox pve-manager/5.1-42/724a6cb3 (running kernel: 4.13.13-4-pve) Mainboard Supermicro X11SSH Broadcom (LSI) 9300-8i Supermicro Gehäuse mit SAS Expander 8 x WD Red 1TB 5400U/min 64GB Ram DDR4 ECC Xeon E3-1270 v5 (3.6Ghz)...

Hello, we have to migrate a rpool on a raidz, to smaller disks and asking for the best way. At the moment we use 2 x Crucial M550 1TB (953.9GB) disks and want to switch to 2 x Samsung 960 1TB (894.3GB). The Samsungs are slightly smaller, so we can't just replace them. The next problem is, that...

hi, ich habe das gleiche Problem. Ich habe 6 Nodes von Proxmox 5.0 auf 5.1 gehoben und bei einem fehlt /dev/zvol. Ich have das Volume rpool/swap entfernt und neuerstellt, aber es hat nichts geholfen. cu denny

hi, it is the MTU 9000! After I set the MTU to default 1500, than the ceph commands working as expected. But I don't understand, why. The MTU is set on all Switch ports and all other hosts. May I have to reboot the switch. What may related ... the new Mon doesn't get a quorum (Quorum = no) I...

hi, the MTU looks fine ... but I enabled debug .... for example: ceph auth list # ceph auth list 2017-10-06 16:42:15.525808 7fea7eaac700 1 Processor -- start 2017-10-06 16:42:15.525869 7fea7eaac700 1 -- - start start 2017-10-06 16:42:15.526561 7fea7eaac700 1 -- - --> 10.3.0.2:6789/0 --...

hi Fabian, that was one of the first thing, testing ceph auth list. On the five nodes, it was working instantly after install ceph (pveseph install) on the node. On the failing node, there is simply nothing. Every command related to Ceph ending in a timeout/hang. The ceph keyring is on the...

hi, i have the same problem. I have six nodes and started with the first one. On the first three nodes, I was able to create a mon. On the forth not. The fifth and the sixth went fine. First I got messages about electing on node 4.... than that this mon had not quorum. I removed all references...

hi, @guletz that isn't the full-truth ;-) Indeed Zabbix and Icinga CAN do execute commands, like scripts for restarting or what ever (sending notifications is the same). Under Zabbix you create triggers and under Icinga events. The only difference is, that you have to create commands first...
