README.md

check_mdstat.sh

This script reads from /proc/mdstat to get the status of a RAID devices.

Other than check_md_raid and [check_md_raid updated](https://exchange.icinga.com/jasem/check_md_raid updated/) not all RAIDs are checked simulataneously, but only one specific. This gives the possibility to query some "performance" data and later add more granular checks.

Arguments

  • --raid | -r: Name of the RAID, e.g. md0
  • --input | -i: Input file. Defaults to /proc/mdstat
  • --debug | -d: More debugging output, cannot be used with icinga2

Results

  • CRITICAL: if any device failed
  • CRITICAL: if the state of the RAID is not active/started
  • WARNING: when recoverying/resyncing
  • CRITICAL: if the number of active devices is smaller than the number of active devices.

Known issues

Probably I did not get things right with spare devices.
