It turns out that the result is a list of all FIFO types: # lsof +aL1 /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p/ = | more lsof: WARNING: access /usr/home/root/.lsof_CA72_UFS: No such file or = directory lsof: WARNING: created device cache file: /usr/home/root/.lsof_CA72_UFS COMMAND PID USER FD TYPE DEVICE SIZE/OFF NLINK = NODE NAME sh 187 root 6u FIFO 4294967295,2264989460 0 0 = 609904 /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p = (tmpfs) sh 2447 root 6u FIFO 4294967295,2264989460 0 0 = 609904 /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p = (tmpfs) . . . sh 96552 root 6u FIFO 4294967295,2264989460 0 0 = 609904 /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p = (tmpfs) sh 98284 root 6u FIFO 4294967295,2264989460 0 0 = 609904 /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p = (tmpfs) But there is still the likes of 402 (df) vs 101 (du): # df -m /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p Filesystem 1M-blocks Used Avail Capacity Mounted on tmpfs 1024 402 621 39% = /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p # du -xsAm /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p/ 101 /usr/local/poudriere/data/.m/main-CA7-bulk_a-default/ref/.p/ So I'm still looking to figure out what leads to the about factor of 4 between the df and du results. =3D=3D=3D Mark Millard marklmi at yahoo.com
