Hi, exactly the same problem, identical servers, those with BCM57412 NetXtreme-E 10Gb have problem, but those with intel cards seems ok. in logs on all nodes problem starts with Oct 5 14:11:45 kernel: [135939.389881] unchecked MSR access error: WRMSR to 0x19c (tried to write...

In this folder you have all rdd files from cluster so no need to connect to all nodes to delete files. I don't think there is api way for this - such functionality would be used when you delete vm, but instead it's rrd file live there for ever.

rrd files are in /var/lib/rrdcached/db/pve2-vm

it was just quick install test to check if it will detect the disk - only this version of old virtio iso was on the machine - by saying 'it works fine' i meant 'it detected disk' even with 134 version

works fine with virtio-win-0.1.134

If i understand corectlly this is what you want (selecting disk image and container)): https://forum.proxmox.com/threads/no-dev-mapper-pve-data-after-ve-5-0-installation.36324/#post-178138

Looks like issue with multicast/igmp on switch/router.

You issue trim to free space on lvm-thin regardless of storage disk type spinner or ssd. On windows vm to force trim run in powershell: Optimize-Volume -DriveLetter C -ReTrim -Verbose

create volume: lvcreate -V100G -T pve/data --name XXX mkfs.ext4 /dev/pve/XXX mount it ( and add it to fstab ) under dir i.e. /templates then add it in storage as type directory and select templates,iso and backup

I would power off server and reconnect battery again - if this not help maybe battery is bad. last idea - you can try to force learn cycle: megacli -AdpBbuCmd -BbuLearn -aALL -NoLog

full bbu info: megacli -AdpBbuCmd -aAll -NoLog to force writeback: megacli -LDSetProp -ForcedWB -Immediate -Lall -aAll

probably writeback disabled get megacli from: http://hwraid.le-vert.net/wiki/DebianPackages get info with: megacli -LDInfo -LAll -aAll and look for Current Cache Policy to enable writeback on the fly with: megacli -LDSetProp WB -LALL -aALL -NoLog

Installing jewel do the trick, 4.4 is connecting to ceph again. Thank you.

add second disk and store those files there and exclude this disk from backup

use fstrim in vm and use virtio iscsi with discard

I have pfsense on one physical nic (vmbr0). pfsense have two virtio devices. Second virtio is set with vlan to communicate with wm's on that vlan. Working without problem. Looks like you have routing misconfiguration. For freebsd remember to set System->Advanced->networking->Disable hardware...
