On supernews a drive acted up over night.

The main purpose of this post is for me to record the information. You might not find much useful here.

The host is running FreeBSD 12 and is a FreshPorts development box.

I saw this error in the logs:

Aug  8 03:17:15 supernews smartd[66288]: Device: /dev/twa0 [3ware_disk_00], ATA error count increased from 22 to 23

smart emailed me because I set that up some time ago.

The email looked like this:

This message was generated by the smartd daemon running on:

   host name:  supernews
   DNS domain: example.org

The following warning/error was logged by the smartd daemon:

Device: /dev/twa0 [3ware_disk_00], ATA error count increased from 22 to 23

Device info:
WDC WD740GD-00FLC0, S/N:WD-WMAKE2379003, FW:33.08F33, 74.3 GB

For details see host's SYSLOG.

You can also use the smartctl utility for further investigation.
No additional messages about this problem will be sent.

I logged in and did some looking. I found the above mentioned entry in /var/log/messages

For the record, here is some of the stuff I saw:

I didn’t try to figure out how to start the rebuild, so I rebooted the server. Yeah, hackish.

If you know what I should have done, please let me know.

It took about 30 minutes to complete the rebuild:

But wait! There’s more!

When the above was completed, I went to Nagios and told it to recheck the faulted items. They came back clean, but a new one appeared: VERIFYING.

Checking the logs again, I found:

I think this is similar to a zpool scrub.

Good night

Now it is time for beer and pizza. It’s Thursday night.
