Hi, I'm running several jails on this box and df doesnt seem to report the filesystems that are mounted within the jail. When using : fbsd5# sysctl security.jail.getfsstatroot_only=1 i see : 22:37|admin@j1:~> df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/md0s1a 495726 148894 307174 33% /usr/local/jails/j1 when setting it to 0 fbsd5# sysctl security.jail.getfsstatroot_only=0 i see fbsd5# df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 253678 56490 176894 24% / devfs 1 1 0 100% /dev /dev/ad0s1e 253678 932 232452 0% /tmp /dev/ad0s1f 29282666 1891884 25048170 7% /usr /dev/ad0s1d 253678 32750 200634 14% /var procfs 4 4 0 100% /proc /dev/ad0s2e 30460626 2 28023774 0% /usr/local/data /dev/ad0s3d 5077038 420388 4250488 9% /usr/local/jails/d1 /dev/ad0s3e 5077038 4 4670872 0% /usr/local/jails/d2 /dev/ad0s3f 5077038 4 4670872 0% /usr/local/jails/d3 /dev/ad0s3g 5077038 4 4670872 0% /usr/local/jails/d4 /dev/ad0s3h 10152148 2 9339976 0% /usr/local/jails/d5 /dev/ad0s4d 24876810 2049060 20837606 9% /usr/local/mdisks /dev/md0s1a 495726 148894 307174 33% /usr/local/jails/j1 /dev/md0s1d 126702 296 116270 0% /usr/local/jails/j1/var /dev/md0s1e 364974 24 335754 0% /usr/local/jails/j1/home devfs 1 1 0 100% /usr/local/jails/j1/dev fdescfs 1 1 0 100% /usr/local/jails/j1/dev/fd procfs 4 4 0 100% /usr/local/jails/j1/proc ... but shouldnt i see from within the jail this : /dev/md0s1a 495726 148894 307174 33% /usr/local/jails/j1 /dev/md0s1d 126702 296 116270 0% /usr/local/jails/j1/var /dev/md0s1e 364974 24 335754 0% /usr/local/jails/j1/home devfs 1 1 0 100% /usr/local/jails/j1/dev fdescfs 1 1 0 100% /usr/local/jails/j1/dev/fd procfs 4 4 0 100% /usr/local/jails/j1/proc because otherwise it's not easy for the jail administrator to know how much space is left on his /var. If there any way to accomplish this on this 5.3-STABLE system ? Previously, on my 4.x systems i was using a kernel module provided by Pawel Jakub Dawidek on his website and it worked wonderfully. Many thanks, Tom
