I hope this is the right mailing list for this question. I bought a new USB3.0
(Intenso slim line 16G) and did a clean root on zfs on it. After 3 months I
noticed a couple of file corruptions in /usr/src and /lib. zpool scrub/clear
changed nothing. So I fixed the single file in /lib by deleting and
reinstalling it, which worked. I thought I do the same with the /usr/src.
Deleted the whole dataset and created a new one, but when I downloaded the src
into the new dataset everything crashed. The system didn’t respond at all and I
had to recover it to a new USB drive. The old one is showing up correct with
camcontrol devlist and gpart shows the correct Partition layout but thats it. I
think its irrevocably destroyed but I´m not sure. /var and /tmp are in a
different pool and atime is turned off on zroot. I am afraid that something
like that could happen again in a couple of months. What did I do wrong and how
can I prevent it. Was it just bad luck with the hardware or should I move
/usr/src also away from the USB to reduce read/write?
Is the memory stick you bought intended for professional use? Flash
usually wears down and if the firmware doesn't take its precautions
you'll loose data simply. Are there any errors printed in dmesg from
GEOM, like read/write errors?
