I'm still a student so when I'll get a job I will change all that.
apparently mixing vdevs with different number of disk is not the best
idea either

One suggestion for the future for better reliability.
Avoid using WDC WD20EARS, they aren't great, and hopeless on SAS
controllers.
Avoid mixing disk brands or models in a zpool.
The different behaviour can trigger issues.

first, dont reboot. if you do you might not be able remount the pool.
the data you see is from the disks that are functioning. listing the
files and copying complete files are two different things. if you
dont have a backup you may need to copy whatever partial data you can
from the broken pool.
now let's start by getting the disks back in good shape.
clear the degraded disk
zpool clear c8t50014EE6561DDB4Cd0p0
reseat the missing disks in the hopes they come back then clear them
check cfgadm -al and make sure they are connected and configured
when you reseat them check the messages (or dmesg) to see if the
system notices the re-insertion. if it does see the disk installed
clear the disks in the pool in effort to bring the pool back to an
operational state.

really weird, I haven't disconnected any disk. For several hours
even if it said that the pool was unavailable I was browsing on it
via nfs. I can't anymore.
What do you think I should do ?
