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>
