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.

FYI, both hard drives and SSDs internally reallocate defective sectors onto working ones when the problem
"block" is written over (it is really just an address, and it changes out the physical storage
location backing 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 hard drives, some sectors going bad is an early sign that there may be a
catastrophic failure in the near future. 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.

Hi Toomas,
Indeed I have problems with the local storage. This notebook has a
single ssd drive (rpool) and scrubbing it finds unrecoverable errors
ml@mosquito:/export/home/ml# zpool status -v
pool: rpool
state: DEGRADED
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

Loosing a few blocks on a 1 TB ssd is acceptable if the OS can avoid
using these faulty blocks in the future. What does zpool do if I do a
zpool clear: the faults will disappear from the status but will the
faulty blocs be avoided henceforth ?
The corrupted files are lost but, if I do "pkg refresh --full; pkg
update -v", I assume they will be replaced.
However if the faulty blocks are not removed from the list of usable
blocks, the faults will happen again and the drive must be considered as
lost and to be replaced

Hello,
I got a surprising error when trying to install packages (any package, even
xeyes) on one of my computers running openindiana: *Error encountered while
retrieving data from: [Errno 5] I/O error.*
Anybody knows what to do ?
Thanks and best regards
Marc
there are two possible causes, either it is some sort of network issue (truss
-f pkg…. and see what will get EIO), or it is issue with local storage (zpool
scrub?).
rgds,
