Update: I have a ZFS filesystem mounted at /var/lib/mysql. I unmounted the filesystem, and the DB started–although with errors (it’s progress, though). Anyone have any ideas if this is specific to ZFS, or just having /var/lib/mysql be a mountpoint? I have several other servers running in the same config (ZFS FS mounted at /var/lib/mysql) running stock mysql with no problems. ---

Hi, I’m using Ubuntu and I had no problem to install and starting PS.5.5.x on it ofcourse I’m not using ZFS. so look like it mightbe issue with filesystem. I’m not sure. Can you provide ls -l for datadir and my.cnf? Can you try to start with option default-storage-engine=myisam ?
