https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254721 crest@rlwinm.de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |crest@rlwinm.de --- Comment #4 from crest@rlwinm.de --- The (long and) short of it is: writing to ZFS can require heap allocations making ZVOLs unsuitable as swap devices (swapping to normal files on ZFS mounts would be even worse). The only reliable solution is to use something simpler as swap space e.g. a gmirror+geli partition. I know this sucks if you have no space left on your disks. -- You are receiving this mail because: You are the assignee for the bug.home | help
