Bring the archive back

The machine has two archives: /mnt/photos and /mnt/reports. The nightly export to ~/export-lab broke off on a read error. Use the kernel log to find the damaged filesystem and bring it back into service: mounted at its old place, writable, with no errors recorded in the filesystem itself and with its files intact.
