@chrcoluk thanks, I'll find out about transport_hugepage and txg. For 5 months my servers have been running with a bad workaround: a cron job which drops the memory cache every 15 min :rolleyes:

Hi, I got the same issue on a second node : https://0bin.net/paste/++4Q1++1#Z9wbvOTP71W4pZylTMoWELlMJEAG0GWg5sLlz-tce0t I think there is a problem with the kernel version 5.4.103-1-pve. I'll try to downgrade on 5.4.78-2-pve since I have a node on this version without kmv crashes...

Hi, My KMV got an out of memory, 3 times since yesterday, any idea ? syslog: https://0bin.net/paste/9hcAzeJa#Wm976GOGKHVrMIZBk1yqz5ptcFqUHQ4824uwcQoxeNs

It works by adding "transport: udp" ! This option only works with "crypto_cipher: none" and "crypto_auth: none ". I think disabling cryptography is not a problem since nodes are connected with a specific vpn. My final corosync.conf: logging { debug: off to_syslog: yes } nodelist { node {...

Average ping is about 14.5ms through tinc vpn and 13.5ms without vpn. Nodes are on different agencies connected by an enterprise network. So it therefore seems difficult to get LAN performance. Currently, the easiest way to edit corosync.conf is to restore the cluster by downgrading to corosync...

But why it works well with corosync 2 ? Is there a way to increase the timeout ? And seems I don't have latency issue (ping ~14ms).

After restarting lrm, crm and corosync : https://hastebin.com/ebaxujaqed After restarting pve-cluster : https://hastebin.com/opedatudiq Here a part of the second: May 13 08:49:45 node3 pmxcfs[29854]: [status] notice: cpg_send_message retry 30 May 13 08:49:46 node3 corosync[27946]: [KNET ]...

@gradinaruvasile I tried but it didn't change anything @t.lamprecht I have the same result on all nodes: root@node1:~# md5sum /etc/pve/corosync.conf 0164366e7424ffcdc99c881ac5c7960d /etc/pve/corosync.conf root@node1:~# md5sum /etc/corosync/corosync.conf 0164366e7424ffcdc99c881ac5c7960d...

Hello, my cluster doesn't works after upgrading corosync from 2.4.4 to 3.0.3 logging { debug: off to_syslog: yes } nodelist { node { name: node1 nodeid: 1 quorum_votes: 1 ring0_addr: 10.10.10.1 } node { name: node2 nodeid: 2 quorum_votes: 1 ring0_addr...

I know it's an old topic but this could help someone : EXAMPLE : rename an LXC container from 100 to 101 1- Be sure there are NO VM with the target id (here 101) 2- Please be CARREFUL, be sure you know what you are doing and check every line and name that it is correct (do not use the names in...

Ok, thanks !

To remove and re-add, I need to previously clone disks ? (zfs clone something...).

Windows

Thanks for your answer. The disk is SATA, is there a way to change into scsi ?

Hi, I have a proxmox with 3 containers and 2 virtual machines, all on a ZFS storage. There is one thing that is automatic with containers and that I would like to do with VMs: I create a virtual machine with a 500 GB disk. On the ZFS, I enabled the "Thin Provisioning" function, which means that...

I just added a patch on an existing feature request : https://bugzilla.proxmox.com/show_bug.cgi?id=1824

I found a solution : update the file /usr/share/perl5/PVE/Storage/ZFSPoolPlugin.pm line 672 (pve 5.2-9): replace my $cmd = ['zfs', 'send', '-Rpv']; by my $cmd = ['zfs', 'send', '-RpvcD']; It is not necessary to restart any service. It's not a very clean solution (and it can possibly be...

Thanks, zfs send -c seems very useful. But is there a way to configure this option through proxmox web interface ? Or in /etc/pve/replication.cfg ?

Hi, Is there a way through proxmox (pve 5) to replicate with compression ? Something like : zfs send -Rpvi tank/vm-100-disk-0@__replicate_100-0_1538395933_ tank/vm-100-disk-0@__replicate_100-0_1538474876_ | bzip2 -c | ssh node2 "bzcat | zfs recv -F tank/vm-100-disk-0"
