Ever since we began using ZFS on the fileserver, we always had to track quota usage, because of the annoying "nfs server not responding" error: when a exported filesystem was full and got write access (including unlink), the server just stopped serving. As of this night, things became more complicated. Webservers either crashed in sync with a "sleepable thread owns a non-sleepable lock" panic or after the following: nfs server 10.0.0.XX:/home/www/XX/YY: not responding nfs_getpages: error -484759920 vm_fault: pager read error, pid 9467 (php-cgi) The not responding filesystem was nearly out of quota. Does anybody know, if these issues with quota'd nfs-exported zfs are fixed in 8.3? with kind regards, Robert Schulze
