This is my first attempt to create a zfs pool manually under Proxmox.
I have created a raidz2 zfs pool with 5 drives (4 WD RED 1TB NAS drives and 1 old 1TB Seagate). I also forgot to specify 2 spares, so I ended up with 5 drives in the pool. One of the HD stopped working properly (sometimes showing as FAULTED, sometimes as UNAVAIL) and the pool became degraded.

I have also created a couple of subdirectories in order to separate the data from the VM's (eg: /storage/share/iso. /storage/share/Movies ...)
storage/share is to be mounted and shared via NFS by a VM. storage/vmstorage is where the vm's are stored.

I was able to access the shared folder from the network and use it as a normal network share with no issues, until the disk broke. I had some data under the /storage/share/* that just disappeared. VM's are fine.
Shouldn't the data still be accessible even in a degraded mode?
Thanks for any help !
