Hi, I went back and checked the reasoning for our not using bgp. Using static routes works too. see https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-43/Layer-3/Routing/Static-Routing/ "You can use static routing if you don’t require the complexity of a dynamic routing...

Spirit that link mentions vrr not vrrp . did you mean use vrr ?

I just check kernlog at one of the cluster nodes, and the dmesg info is very different. there are lines like these: Sep 12 07:39:41 pve2 kernel: [ 3385.014666] INFO: task jbd2/rbd0-8:4096 blocked for more than 120 seconds. Sep 12 07:39:41 pve2 kernel: [ 3385.014698] "echo 0 >...

Hello, i added this to /etc/pve/pve-local crontab and got a hit from a standalone pve system we use for off site backups. cron: 55 */4 * * * root dmesg -T | grep hung email from cron [Sun Sep 12 09:45:13 2021] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this...

Hello Spirit As far as I know, and will recheck we use VRR and do NOT have bgp and ecmp set up. would you suggest we just use VRRP ? my understanding of networking is not great and I could use advice on which way to set things up. we have 5 pve hosts, 1 pbs host, pfsense and 4 netgear...

- yes they are used as router. per the following in pfsense lldp . ------------------------------------------------------------------------------- LLDP neighbors: ------------------------------------------------------------------------------- Interface: em0, via: LLDP, RID: 1, Time: 0...

however I am certain that it is likely that I had or have something mis-configured in software settings. Or there is a bug at the switch etc. usually operator errors occur more often then bugs.

- we use connect-x4 and -x5 - the mlag switches are mellanox 2500sn running cumulus . as for the loop i am certain the cables go from the connect-x* cards to the switch. cumulus has this command that shows the lldp of each connection. I ran this on both switches to verify that the port...

so in our case the network we think was the cause. I will leave the thread open as someone else posted their issue, and will wait a few days to make sure there is not a repeat.

also we get emails when ceph -s shows warnings and saw these: cluster: id: 220b9a53-4556-48e3-a73c-28deff665e45 health: HEALTH_WARN 1 slow ops, oldest one blocked for 82322 sec, mon.pve4 has slow ops services: mon: 3 daemons, quorum pve15,pve11,pve4 (age 22h)...

1- I am fairly sure it is related to this seen at dmesg on pve hosts # dmesg|grep hung [Sun Sep 12 07:39:32 2021] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [Sun Sep 12 07:39:32 2021] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [Sun...

Hello I am seeing slower migrations with pve7 then pve6 . We do have a network issue that I have been trying to track down over the last week, which is probably the cause. However I wanted to see if others have noticed slower migrations. thank you for reading this.

thank you Fabain. this is what worked in our case: proxmox-backup-client backup etc.pxar:/etc home.pxar:/home -exclude */.cache/ -exclude */Downloads/ -exclude */.thunderbird/*/ImapMail 2>&1

Hello i am trying to get -exclude to work. we do not want to put a .pxarexclude at each system proxmox-backup-client backup etc.pxar:/etc home.pxar:/home --exclude home/*/.cache:home/*/.thunderbird/*/ImapMail I've tried a few different ways over the last hour. each time i see: warning...

after installing pbs and before doing any config. when creating a zpool use same name as original system 0- the transfer will create the zfs on the target. if target exists receive failed here. [ could be because i had already set up a datastore on the target . in any case i am unsure on...

probably there are just few more things besides datastore and /etc/proxmox-backup/ to scp / rsync over . do you happen to know the location of keys etc? after that move IP address .. PS thanks for the zfs send/rcv suggestion .

Hello we are moving pbs to new hardware. zpools / zfs have been set up with same names rsync of datastore is in progress and will take some hours. for configuration , besides /etc/proxmox-backup/ is there anything else that needs to be copied over?

so i went and removed pve , installed bullseye rebooted and installed pve . so all is working. the issue started with the hold of ceph-common . our other stand alone system had no issue with pve6 to pve7 when ceph-common was un held .

also this is a standalone system that does not use ceph
