when I run ls on /dev/disk/by-id I see same disk by two different number one with scsi and one with wwn which one should I use? ls -la /dev/disk/by-id/ |grep part2 |grep sde lrwxrwxrwx 1 root root 10 Aug 24 16:35 scsi-36c81f660e2ff3a002926a14604c4fc5d-part2 -> ../../sde2 lrwxrwxrwx 1 root...

Ok great Thank you everyone. this is the link I was looking for. it seems not that complicated at all.

isn't there any corosync config that requires changes? just /etc/network/interface, /etc/hosts, dns will that do it?

I have five node cluster up and running in network X. We are moving datacenter and moving this hardware to new network segment Y. What is best way to redo this? I want to keep all installation and just change IP/netmask/gateway and have cluster back up and running. Then I am redo IPs for LXC...

I was looking around some example on ES on Proxmox. Didn't find much out there. I have finally setup 10xR630 Proxmox cluster and two LXC on a node for first five system. which has dual NVME. using one nvme per LXC (bind mount) as direct mount or pass through does not give enough write...

Bind mount point is 100% better then Storage backed mount point. I run five parallel dd to both and speed is almost double in bind mount point Used same old disk both both test, 7.2k disk. dd if=/dev/zero of=test1 count=10000000 & This is to storage backed mount point, 5120000000 bytes (5.1...

oh well finally decided to test something by self. I will add both type of mount to one system and run dd from host and from LXC. Will put a result out there. Hopefully will help someone

problem with storage backed mount point I saw that when I remove the LXC it remove the storage with it. while bind mount point I don't loose the data.

Which one gives me better performance? I am using is privilege LXC for this LXC I am going to use full 1tb SSD that is available on host. host has two 1TB SSD and going to use two LXC one SSD per host. But OS will be located on separate disk.
