[OpenIndiana-discuss] io errors in rpool, was surprising error when I try to install a package

Thanks. Indeed this is what I thought. In my case the ssd was dying (the 
bios couln't even see it anymore). I had to replace it.

With SSDs it is actually more internally complex than hard drives, but the principle is the same: the OS doesn't track the defective sectors, the drive does, and fills in with spare working sectors when it gets new data, so the OS doesn't have to care.  This is what the "current pending sectors", "offline uncorrectable", etc in the SMART attributes mean.

For SSDs, it isn't as clear what it means - it could be a one-time event from unexpected power loss, if the drive isn't robust to that (some drive models are designed to handle it, others lose recent writes, and some become bricks), or being powered off for a very long time, or outside its temperature range, or it could be manufacturing defects, etc.
