mysql-standalone OOMKilled May 8 18:05 (anon-rss 2 GB at the 2 Gi limit). innodb_buffer_pool_size=1Gi plus connection buffers and InnoDB internals don't fit in 2 Gi. Bumping limit to 4 Gi (request 3 Gi) leaves headroom without changing the buffer pool config. /srv/nfs was at 90% (1.7T / 2T); grew the underlying pve/nfs-data LV 1 TiB online and ran resize2fs (now 60% used). Triggered by surfacing during the 2026-05-09 IO-pressure post-mortem; thinpool had ~4.6 TiB free. The post-mortem also covers the stale-NFS-client trigger (legacy /usr/local/bin/weekly-backup pointing at the decommissioned TrueNAS IP) and the resulting wedged kthread on the PVE host. Script removed and node_exporter restarted out-of-band; kthread will clear at next PVE reboot. See docs/post-mortems/2026-05-09-io-pressure-stale-nfs.md.
