Hi, I have been running FreeBSD 9.0-RELEASE from a USB stick running ZFS. I have created swap file on zfs volume using the md driver. Swapinfo shows Device 1K-blocks Used Avail Capacity /dev/md0 4194304 0 4194304 0% The system has hung twice and all I can find in the log is Mar 22 03:17:30 server kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 927, size: 4096 Mar 23 09:00:26 server kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 55, size: 4096 Mar 23 22:01:26 server kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 49, size: 4096 Mar 24 04:00:38 server kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 60, size: 4096 As the swap is on zfs, I assume it is not failing. Do I need to move swap off of ZFS? Thanks
