This is more then true IF you try to use a volume on multiple hosts SIMULTANEOUSLY, in which case its not "good practice" its downright forbidden. There are ways to accomplish this with central metadata management (eg, lustre) but not just...
Hate to break it to you, but you only have one pair of interfaces in a lagg; while I cant see what speed the underlying interfaces are connected at, they will not be different per vlan.
You are also comingling this same bond for all your...
at this point it may be worthwhile to see how your network is set up.
Do you want to post the content of your /etc/network/interfaces for your nodes, and describe how they are physically interconnected?
looking at your layout... you are BRAVE. I wouldnt go to production with such a lopsided deployment, and without any room to self heal.
brave is a... diplomatic word.
To add to that- I was initially very excited about Veeam integration until I actually deployed it. It is very much alpha level imo, and I ended up rolling up a pbs instance in my environment despite having a Veeam store already in place (We're a...
look for processes in uninterruptible sleep state, eg
ps -eo ppid,pid,user,stat,pcpu,comm,wchan:32 | grep " D"
post the output if you need further troubleshooting assistance.
1. why is your mgr down?
2. post the content of ceph osd tree and ceph osd df (if you even can)
3. would be good to know crush rules for all 14(!!) of your pools. (why do you have 14 pools?!)
Generally speaking, it looks like you dont have...
troubleshooting USB boot is always the same:
1. use dd to directly copy the iso to the USB (eg, etcher on windows)
2. If it fails to fully boot, use a different USB device
3. if it fails to fully boot, use a different USB port on the host.
4. if...
Generally speaking, an even number of nodes doesn't pose a problem, its just that with 4 nodes your minimum for quorum becomes three nodes instead of two since quorum requires round(n/2+1).
Thanks for the detailed benchmark!
As for your question, it seems to me that there are only two sane ways to utilize the storage:
zfs striped mirror (or two seperate mirrors)
mdadm striped mirror (or two seperate mirrors)
mdadm+lvm will be...
Installing OFED on debian is not done using apt directly. Once you decompress the tarball there is an installation script that has to run. It will prompt you to install its prerequisite packages before it will complete installation. Also, in some...
your config is unworkable.
While you didnt provide your actual crush rules, I can already see they can never be satisfied.
Consider: you have 3 nodes.
node pve2 15.25TB HDD, 1.83TB SSD
node pve3 7.27TB HDD, 0.7TB SSD
node pve4 0.5 HDD, 0.9 SSD...
