The data-notify.sh ZEDLET serves a very similar purpose to io-notify.sh, namely, to generate a notification in response to a particular error event. Initially, data-notify.sh was separated from io-notify.sh since the "data" zevent does not (as I understand it) pertain to a specific vdev device. This stands in contrast to the "checksum" and "io" zevents (both handled by io-notify.sh) that can be attributed to a specific vdev. At the time, it seemed simpler to handle these two cases in separate scripts. This commit adds support for the "data" zevent to io-notify.sh, and symlinks io-notify.sh to data-notify.sh. It also adds the counts for vdev_read_errors, vdev_write_errors, and vdev_cksum_errors to the notification message. Signed-off-by: Chris Dunlap <cdunlap@llnl.gov> |

Shell scripts are the recommended choice for ZEDLETs that mostly call other utilities and do relatively little data manipulation. Shell scripts MUST work on both bash and dash. Shell scripts MUST run cleanly through ShellCheck: http://www.shellcheck.net/ General functions reside in "zed-functions.sh". Use them where applicable.
