Update: I can't tell that ionnice helps at all, but entering anything into bwlimit seems to slow the backup down.

I've also read through this posting, which basically shows the same as I'm seeing. Would a ICSI share be expected to fair better?

I saw in another thread that this might be helpful. Currently running a backup. THis VM is doing nothing, and is currently the only VM running on this node (R720, dual 8 core, 192GB ram, dual 10G copper broadcom ethernet). Can't tell if these are good or bad, but the second set seems to say a...

And now I've tried putting my new FreeNAS server on the main cluster 10G network 100, and still get ~80MB/s backups. Frustrating.

So, I've tried IONOICE, BWLIMIT, and local disk, and I can't tell that any of these are getting me faster backups. Is someone actually doing better than this, and if so what settings did you use?

Nope, my migrations are very fast now, on the whole, so that's good. I also added all 3 networks to my CoroSYNC config, and added teh cluster 10G network at ring0 just in case that was slowing things down and (after a brief scare where I boofed the config) that's working, but backup and restore...

So, if I check the route it seems like it should be going out the right bridge interface to get to my FreeNAS servers on the 101 network.

UPDATE: I was able to stop the cluster service, force it into local mode, and make the edits in the /etc/corosync directory, reboot, and get the cluser back up by using this article, so I think I'm back up...

Hello, I really need some help. I have a 4 node cluster, and I was trying to add redudant ring addresses to the cluster and blew it up. I tried to follow this guide, I did copy and backup the configuraiton. I made a mistake, and now when I try to edit the Corosync file I get a permissions...

I did setup a 1G corosync network and this went away.

I'm realizing that I don't know enough about Linux networking as I need to, and try as I might I can't seem to gleen what I need to know from searches. Here's a picture of what I'm trying to accomplish. I think this is the actual issue that I started working in this post. 192.168.100.0/24...

UPDATE: I just found the migrate option in datacenter.cfg and set the migration to be on my 10G host network and now migrations are awesome (2020-03-06 23:36:34 migration speed: 819.20 MB/s - downtime 594 ms), so I think I just need to add a default route somewhere for the SAN traffic flow...

UPDATE: Somebody on Reddit tipped me to try ionice in vzdump. I just set it to 2 with little affect. The previous backup too 16:42, this backup 16:03. I guess I could look at the local temp directory next. If I do that, does it need enough space for the entire VM, or will it start to spool...

Backup from node 4 to new FreeNAS peak and stay a about 100Mbps. Note that the VM is on FreeNAS host #2, and the backup is going to FreeNAS host #4, so same network but didn't boxes. () INFO: starting new backup job: vzdump 505 --storage FN4_Backup --remove 0 --mode snapshot --compress lzo...

I'm looking to improve my backup (well, and overall VM, but that's a story for another day) speed in PVE. I've looked around, and haven't found anything on optimization, or even what normal or 'good' performance would be. I have 4 nodes, all on PVE6.1-7, all 12th gen Dell R620/R720 machines...

Yea, thanks, that's really helpful actually. My search skills might suck, but that's no crime, and you can choose to not reply rather than lambaste folks for having weak search skills. I'm not a unix guy really, and this is for my home setup; I'm an engineer but I don't do this for a living...

S-u-p-e-r helpful, Dad... Oh, and I'll be late for dinner. Thanks!
