I have strange problem with our cluster. Cluster works fine, no issues, I can migrate VM between each node without issues for example. I have 5 nodes from prx01 to prx05. If I login to prx02 and try to see "Summary" page of prx05 or open console on VM running on prx05 I will get "Connection...

Hello, we've tried to upgrade our cluster running 7-4-15 to latest 8. Pve7to8 didn't showed any problems, upgrade was fine as well. The issue is that it does not boot anymore after reboot, neither with new 6.5 kernel nor with old 5.15.x This is what I see in IPMI console, it just stuck I've...

btw, I fixed backup. The problem lies in this line (somehow it didn't get my attention because of INFO level) INFO: tar: ./var/cache/apt/archives/util-linux_2.31.1-0.4ubuntu3.3_amd64.deb: File shrank by 501040 bytes; padding with zeros after removing this file on container, everything works fine.

Thats true, but I do backups to NFS which have pleynty of space, I even deactivated local "tmpdir" in /etc/vzdump.conf And like I've said other containers does no have problems with backup.

Hello, I have proxmox with bunch of LXC containers, I do backups of them regular using "backup" option in Proxmox to my NFS share, everything works fine except one container. I always get this message. command 'set -o pipefail && tar cpf - --totals --one-file-system -p --sparse...

Hello, I have a strange problem. My Proxmox uses ZFS Raidz2 with 68 TB usable space, and has one VM with 40TB big volume. At the moment about 30 TB are already in use on this disk according to `du` running within VM. But ZFS shows that disk uses all 68TB. How is it possible? The VM in question...

I'm not sure where I'm wrong, SSD are faster than spinning drives, even the consumer ones (I'm not talking about 15k SAS enterprise drives of course). I know the link, because I've build Ceph clusters before and agree, you don't want to use cheap SSDs in Ceph clusters (I had good experience with...

Thanks for explanation, for me it still doesn't look right that system had so much IO wait with "sync=standard" which is default. I would understand it on spinning drives, but SSDs, even consumer grade, should be a bit faster. So not sure if it's bug or "feature"

Hi, this post is part a solution and part of question to developers/community. We have some small servers with ZFS. Setup is simple, 2 SSDs with ZFS mirror for OS and VM data. zpool status pool: rpool state: ONLINE scan: scrub repaired 0B in 3h58m with 0 errors on Sun Feb 10 04:22:39...

But I still can create 2-node cluster just without HA, so I can migrate VMs to another host for e.g. kernel upgrades, right? Thanks for the link btw.

Hello, with proxmox 3.x it was possible to have two-node cluster using DRBD, since 4.x two-node HA is not possible and DRBD isn't supported anymore. I think storage replication with ZFS can replace DRBD somehow, testing this right now, but what is the status with HA? I saw on forum, that...

first of all, please post it to ceph's mailing list too, http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com/ you will get much greater response. - not sure about performance, but 3/2 is default these days and it's not coincidence, 3/1 is not recommended anymore. - 6 OSDs with SSD are...
