zfs destroy snapshot doesn't free space

[Andreas Mayer]

In the meanwhile, some Web applications (they don't even access /var
but only /srv) don't work anymore because of very strange "file not
accessible" and "file not found" errors although I haven't changed
anything and the file system isn't full or something like that. I
think the whole pool or serveral file systems are corrupted... can
that be true or am I panicking? Is there any chance that I can repair
it without reinstalling the whole system?
