I logged into one of my Synology NAS boxes and saw a flock of disk errors:
And these, too:
I decided to replace the disk, even though it was part of a RAID 6 volume. But then I noticed that the Synology OS was out of date. I upgraded to the supposed latest version, restarted, updated some apps that wouldn’t work with the new OS, and noticed that Synology was now offering me yet another OS upgrade. I took it. It then was happy:
The new OS sure is pretty, but I couldn’t figure out how to shut it down from a web browser, so I went down to the server room, shut it down with the power button, pulled the bad drive, plugged in a new one, and powered back up.
When the OS had booted, I found the drive in the storage manager and told the system to effect a repair. I looked around for a progress bar. It took a while, but I finally found a down arrow that looked promising. I clicked on it, and found what i was looking for:
I looked at the disk info on the new disk, and saw that it must have had a one-day burn on at the factory:
The new OS GUI is slick, but short on tasteful colors. Here’s an overview of the load during the rebuild:
Unsurprisingly, a rebuild is more reads than writes:
It looks like it will take about 32 hours to rebuild. I updated the OS and apps on my other Synology boxes. Good thing I didn’t have much to do today.
[Added later. The rebuild slowed down. It now looks like it will finish a little over two days after it started.]
