 ./quotacheck -avu
quotacheck: WARNING -  Quotafile /home/aquota.user was probably truncated. Can't save quota settings...
quotacheck: Cannot remount filesystem mounted on /home read-only so counted values might not be right.
Please stop all programs writing to filesystem or use -m flag to force checking.
