  21. AgentI'm looking at line 4 of the fstab, which mounts /srv/data by UUID and has a device timeout set. The device is missing, so I'm planning to add the nofail option to only that line, after backing up the file first. I'm checking whether the firewall blocks the in-place sed edit, and it isn't on the list, so that should be fine.

PayPal-Request-Ids: two ticks per money call

Each call is written to the outbox with its PayPal-Request-Id before it is sent, so a retry never moves money twice. PayPal's synchronous answer is the first tick; the verified webhook is the second.

Diagnosis and plan

a bad /etc/fstab entry stops the boot in emergency mode

  • [ TIME ] Timed out waiting for device dev-disk-by\x2d■by-uuid/7d1e3c55-2b8f-4c1e-9a0d-5f2a61c0b9e4.
  • [DEPEND] Dependency failed for srv-data.mount - /srv/data.
  • [DEPEND] Dependency failed for local-fs.target - Local File Systems.
  • You are in emergency mode. After logging in, type "journalctl -xb" to view

1. Confirm the fault by logging in at the emergency shell and running journalctl -xb to check for the fstab mount failure of /srv/data. 2. Open /etc/fstab and find the entry for the UUID 7d1e3c55-2b8f-4c1e-9a0d-5f2a61c0b9e4 or the /srv/data mount point. 3. Mark that line as nofail or comment it out so the boot does not wait on the missing device. 4. Save the file, then run systemctl daemon-reload and mount -a to check that the remaining entries parse. 5. Run systemctl reboot and confirm the system reaches a login prompt.

Owner probe, fixed at checkout

A capture happens only after this check passes twice, far enough apart, with no failure between.
