#ZFS COMMANDS TO MONITOR DISK HEALTH INSTALL#
It is included with ZFS and can be installed as follows: apt install zfs-zed vi /etc/zfs/zed.d/zed.rc zed.rc This file should be owned by root and permissioned 0600. To expand the zpool by adding a new disk use the zpool command as given below: zpool add -f mypool sde. That was probably foolish of me.Īlso, none of this will harm your data, you are only typing in commands to gather information so we can assist you. ZFS has and Event Daemon (ZED) that monitors all ZFS events (such as a scrub being completed) and sends an alert email when an event occurs. I assumed you had been running this for a while because you are running FreeNAS 9.1.1.
Those emails could save your data!Īnd I did a foolish thing, I assumed something. You should setup your FreeNAS network and email address info so you can receive email messages when things go wrong with your NAS. To retain the format of text you should be using code brackets (these are the braces you see # when you are entering a message, just below the Font Size selection). Do this for all drives ada0 through ada4: In the shell type the following and record the drive, ID values 5, 194 thru 198, and include the title of each value, for instance 194 should be temperature. I don't want to distract from this but here is what I'd like to see.
I think solarisguy is giving you sound advice to identify your problem. If you have a slow CPU and a RealTek NIC, you are looking to see slow network performance. It is true that they are not as fast as an Intel NIC however sometimes it's only slightly. They work good providing you have a good CPU. First I'd like to address the comment about the RealTek NIC, I have never seen one be the cause of a system failure.
