Hi, we are running several webservers on 8.1-RELEASE-p12 which deliver their data from NFS. 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
