The user explicitly requested expanding drg-k8s disk storage to 512 GB to resolve disk pressure, and explicitly authorized proceeding while Wiki.js was unavailable. The existing 256 GiB VM disk was expanded to 512 GiB (549755813888 bytes). No data was deleted. The user performed the reboot after the live SATA rescan did not expose the new capacity.
Owner: host infrastructure administrator. Purpose: existing drg-k8s operating system and Kubernetes root disk. Source: Kryptovisor /mnt/fastdata/disks/drg-k8s.qcow2; libvirt domain drg-k8s, UUID 1d198cfa-3514-4e1d-a39b-cccc009779bc, target sdb on SATA, guest /dev/sda. Existing fastdata ZFS pool was healthy, with 2.54 TiB available and no dataset quota. This enlarges an existing VM allocation; virtual capacity is bounded at 512 GiB, while qcow2 metadata and snapshots can add host-side overhead. No storage-tier migration or retention changes. Existing host-health-monitor and codex-storage-hygiene timers verified active. Build-placement restrictions remain applicable; additional root space is not an authorization to move AutoCoder builds here. Backup coverage was not verified in this task; no new snapshot was created. Growth rate was not measured.
virsh blockresize drg-k8s /mnt/fastdata/disks/drg-k8s.qcow2 512GiB on Kryptovisor. Hypervisor reported the requested capacity.growpart -N /dev/sda 2, then ran growpart /dev/sda 2 and resize2fs /dev/sda2. Root filesystem was grown online at 18:03 UTC. Partition start and identifiers were preserved.sfdisk --verify /dev/sda: no errors. Root write, fsync and readback passed; task-owned probe removed.This verifies storage relief and Wiki.js recovery, not every hosted application. Hypervisor domblkerror continued to show sdb: no space from the earlier state even after successful resize and guest reboot; pool capacity, guest filesystem writes, and kernel checks did not show a current space exhaustion or new filesystem I/O error. The old hypervisor status was not forcibly reset. No filesystem shrinking or automatic rollback is safe after online growth; any recovery requiring restore or reduced disk size needs a separately reviewed offline procedure and verified backup. No temporary task files remain.
