This is a disk I/O report for the last 30 days of every #Proxmox node of a cluster. Something happened around March 28 that caused high disk usage, and I can’t figure out what. The replication tasks are failing randomly, and actually, any disk operations are slowed down. Also, there are no significant changes in CPU, RAM, or network usage. I was hoping to find which LXCs are causing this, but they all have similar disk IO graphs. Well, shit. #homelab #ProxmoxCluster #HighDiskUsage #zfs #mystery

Ok, that was kinda premature and stupid panic. #Beszel agent was not reporting Disk I/O until the recent update. All agents are updating automatically, and that happened just around March 28-30. After that, the data began to flow. In fact, I have sudden disk issues only with a single #Proxmox node, and it is clearly visible on the IO pressure stall graph. Spikes before May 30 are backups. Then it went crazy. #homelab #zfs
