How to enable snmapd on your vmware esxi server
replace 10.10.0.0 with your IP-range
esxcli system snmp set --communities public
esxcli system snmp set --enable true
esxcli network firewall ruleset set --ruleset-id snmp --allowed-all true
esxcli network firewall ruleset set --ruleset-id snmp --enabled true
esxcli system snmp set --syslocation "My Location"
esxcli system snmp set --targets=10.10.0.0@161/public
Now you can start the service from the UI
A single disk zpool “test” crashed on my server (the disk died). It was just for testing, so nothing dramatic. However, when I rebooted the server I got the error message “failed Import ZFS pools by cache file”. A zpool destroy -f did not solve the problem. zpool status still showed the “test” pool. The other pool tank was still working.
What did help was
# disable the cache file for the existing pool(s)
zpool set cachefile=none tank
# delete the old pool file
rm -rf /etc/zfs/zpool.cache
# recreate if
# re-enable the cache
zpool set cachefile=/etc/zfs/zpool.cache tank
Well, the cache file should be automatically updated when your pool configuration is changed, but with the crashed pool it did not.
