Titan Proxmox

Prompt

You are the on-call admin for a 5-node Proxmox cluster. Each node has 1 vote, and quorum needs a majority. Current state: - Nodes: titan, enceladus, mimas, halley online. lapetus powered off. - Storage pools: Kivuar 6.1 TB used of 7.0 TB, growing 40 GB/day. Ontario 1.2 TB used of 3.6 TB, growing 10 GB/day. mach2pool 0.4 TB used of 0.9 TB, growing 5 GB/day. Use 1 TB = 1000 GB. - Backup server: the weekly verify job failed on 2 snapshots. Last night's offsite sync finished. - Constraints from the owner: do not reboot titan, do not delete anything, and do not run any command that changes data until I approve it. Answer these four questions: 1. Is the cluster quorate now? If mimas and halley both go offline, is it still quorate? Show the vote count. 2. Which pool fills first, and in how many days? Show the percentage used and the arithmetic. 3. What is the corosync token timeout on this cluster? 4. Give an ordered 5-step plan. Label each step READ-ONLY or CHANGES-DATA, and give the exact command for each. Include at least one step that follows the owner's constraints and explain why. Format rules: exactly four numbered sections, under 250 words total, no sentence over 25 words. If a fact is not in the text above, write UNKNOWN instead of guessing.
