Hi, I found when we exhaust memory, tmpfs will not be able to write anything into it and cannot mount it. I use ZFS and TMPFS at the same time. Florence# cd /usr/src && make buildworld > /dev/null & Florence# uname -a FreeBSD Florence.tamama.org 7.0-RELEASE-p1 FreeBSD 7.0-RELEASE-p1 #5: Mon May 5 00:36:32 CST 2008 root@Florence.tamama.org:/usr/obj/usr/src/sys/KERNEL amd64 Florence# mount -t tmpfs -o rw,size=1024000 tmpfs /tmp/tmpfs mount: tmpfs : No space left on device first 5 lines of top: last pid: 26893; load averages: 1.50, 1.58, 1.48 up 12+01:43:49 05:40:51 146 processes: 2 running, 144 sleeping CPU states: % user, % nice, % system, % interrupt, % idle Mem: 406M Active, 574M Inact, 1775M Wired, 83M Cache, 214M Buf, 126M Free Swap: 1024M Total, 1024M Free I think there should be a "lower bound" size limit. Does TMPFS use kernel-space memory?
