(ZFS RAIDZ2) Missing around 1TB in files!

[Pheoxy]

So I've had a zfs raidz2 pool running for a while but due to work I haven't been using it in a while. As in I get home go to sleep and then work again.

So I've come back to my NAS and was about to watch some TV shows and every few episodes are coming up 0 bytes. I know these files were fine before and also checked around the NAS and its heeps of files that have the same problem.

Does anyone know what I can do to fix this and what caused it?

post the status of the zpool,
if its says no errors then its not zfs.

I'm assuming this is what you meant.

so one of your drives failed? you should look into that.

but zfs did not report any file system errors. so it must be something you have done.

I'll set everything to 777 on my shares and copy it all off. Would it be skipping files if it doesn't have the permissions to copy? It should at least come up I'm sure.
