Aalexskysilk replied to the thread Watchdog Reboots.then you need to use QOS and/or limit the bw of your backups. this will happen again.

Aalexskysilk replied to the thread Watchdog Reboots.are you sharing interfaces between PBS and corosync? if so, break them up.
-
Aalexskysilk replied to the thread Watchdog Reboots.assuming the logs provided are up to the time of death, this is the likely cause. are you backing up to an NFS target?
-
Aalexskysilk replied to the thread Proxmox Cluster Random Reboot.post the content of your /etc/network/interfaces files. note which interface is being used for what purpose.

Like.
@alexskysilk You're right to call that out. "Very small environments" was a poor choice of words on my part. The distinction I was trying to make isn't about node count, it's about business value. We have customers running three node clusters... -
Aalexskysilk replied to the thread HA configuration for node migration/restart only.hmm. this is where a feature request for "last state" is probably your next step :)
-
Aalexskysilk replied to the thread HA configuration for node migration/restart only.yes. For your test vms (and other non critical) just set the HA request state to ignored. you can still live migrate them just fine.

Aalexskysilk reacted to bbgeek17's post in the thread Questions about Proxmox with shared storage, Redundancy and support for SCSI-3 PR with Like.
Hi @nvanaert , There's quite a bit to unpack here. First and foremost, Proxmox VE does not monitor storage or network path health. An All Paths Down (APD) condition will not result in a node fence, nor does it interact with the VM HA subsystem...
-
Aalexskysilk replied to the thread HA configuration for node migration/restart only.You realize that HA request state of started means, you know, that it should be started. If you dont want that, set a different request state.
-
Aalexskysilk replied to the thread Storage for small clusters, any good solutions?.This implies that the operator has both the skill, experience, and the wherewithal (not having a dozen other responsibilities) to understand the docs and apply them. Ceph is not attractive at the low end precisely because it requires engineer...

Aalexskysilk replied to the thread Best RAID for ZFS in Small Cluster?.If by redundancy you mean disk fault tolerance, the higher the value after "raidz" the higher the fault tolerance. In practice, raidz2+ (never use single parity raidz unless prepared to lose the pool at any time) performance= striped mirrors...
-
Aalexskysilk replied to the thread Pardon my less-than-intelligent question, but is there a way to install Proxmox on a Ceph cluster?.Good plan. I hope you understand that this experiment will not ever be worth any money you put into it. You already have a working solution- and if the "politics" of the money prevent you from putting together a sane configuration you're just...

Aalexskysilk replied to the thread Snapshot causes VM to become unresponsive..I'm sure there would be readers grateful for any such information. any reason you're not just posting it?
-
Aalexskysilk replied to the thread Request: SAS HBA LUN Sharing Between Proxmox Cluster Hosts (Like VMware).@RodolfoRibeiro If you want more direct assistance, post the content of (from both hosts) lsblk multipath -ll -v2 if you have system logs available from the point in time when your vm became corrupted, would be good to look at what happened.

Aalexskysilk reacted to bbgeek17's post in the thread Request: SAS HBA LUN Sharing Between Proxmox Cluster Hosts (Like VMware) with Like.
Hi @RodolfoRibeiro , thank you for clarifying. This matches my initial understanding of your situation. SAS and iSCSI are transfer and connectivity protocols. While the article I suggested is using iSCSI as example, once you are beyond basic...
-
Aalexskysilk replied to the thread Request: SAS HBA LUN Sharing Between Proxmox Cluster Hosts (Like VMware).For the generations of hardware where iscsi and SAS were offered as available SKUs there was no meaningful performance difference- 16G FC simply had more headroom to fill cache. When 25GB iscsi product started shipping, THOSE were faster (even...

Aalexskysilk reacted to Johannes S's post in the thread Pardon my less-than-intelligent question, but is there a way to install Proxmox on a Ceph cluster? with Like.
Although they were about replicated pools (so no ec) following reads might serve as a hint why (outside of experiments/lab setups) it's not a good idea to go against the recommendations...
-
Aalexskysilk replied to the thread Pardon my less-than-intelligent question, but is there a way to install Proxmox on a Ceph cluster?.K=6,M=2 results in 6 data strips per 8 total. 6/8=0.75 in replication you have 1 data strips per 3 total. 1/3=0.33 its not exactly the "same" availability because survivability in a replication group is much higher; you need one living osd per...

Aalexskysilk replied to the thread Pardon my less-than-intelligent question, but is there a way to install Proxmox on a Ceph cluster?."lower" and "higher" are subjective. Ceph achieves HA using raw capacity. suit yourself. this is not a recommended deployment. You are far better served by just having two SEPERATE VMs each serving all those functions without any ceph at all-...
