ZFS plugin returns SSD cache errors.

[Fever-Wits]

Hello, I use the zfs plugin to monitor the zfs pool. I have added an SSD for cache. I occasionally get the following error in librenms: ZFS L2 cache has experienced errors

As far as I understand, the plugin outputs information from: /proc/spl/kstat/zfs/arcstats As far as I understand the script takes l2_writes_error, l2_cksum_bad, l2_io_error and outputs them.

I am trying to understand what the errors are and what they are due to. I call the Dell R720 + HBA to the front backplane. OS: CentOS 9 Streem In zpool status I have no SSD errors. I looked through the logs and I don't see any errors anywhere. Can anyone direct me to what I should be looking for as a problem or is it just the script reporting wrong

# cat /proc/spl/kstat/zfs/arcstats | grep err
l2_writes_error 4 0
l2_io_error 4 0
l2_rebuild_io_errors 4 0
l2_rebuild_dh_errors 4 0
l2_rebuild_cksum_lb_errors 4 0

# ./scripts/zfs | jq | grep err
