Thank you. Just to be nit-picking over the details, * A zpool dataset hosting swap may lock-up. * As work-around, we want to enable SSD-based 1G partition as fall-back swap (only last resort) * My system DOES suffer from lockups (when poudriere is compiling), but the spindle-HDD hosted zpool/swap is not why (swap space usage barely maxes at 15%). The lockup is probably due to CPU (unlocked core). * Does a /dev/gconcat device, (zpool first, SSD partition as number 2) function as designed (and I mean does the SSD partition work as fallback), if and should the primary swap on zpool/swap have a lockup for some reason. Difficult to call IMHO. Thanks again. ----- FreeBSD-11-current_amd64_root-on-zfs_RadeonKMS -- View this message in context: http://freebsd.1045724.n5.nabble.com/Questions-re-swap-on-zfs-tp5848720p5864850.html Sent from the freebsd-fs mailing list archive at Nabble.com.
