Description
At least on FreeBSD available space is calculated by (number of blocks * fragment size).
from statvfs(2) manpage:
f_frsize The size in bytes of the minimum unit of allocation on this file system. (This corresponds to the f_bsize memβ ber of struct statfs.) f_bsize The preferred length of I/O requests for files on this file system. (Corresponds to the f_iosize member of struct statfs.)
For example,
$ df Filesystem Size Used Avail Capacity Mounted on /dev/md0 62M 8.0k 57M 0% /ufs tank 27M 31k 27M 0% /zfs tmpfs 64M 4.0k 64M 0% /tmpfs localhost:/zfs 27M 31k 27M 0% /nfs
and see (f_avail * f_bsize) for them
statfs("/ufs") = 60,313,600 (avail = 14,725, bsize = 4,096, iosize = 32,768) statvfs("/ufs") = 482,508,800 (avail = 14,725, bsize = 32,768, frsize = 4,096) statfs("/zfs") = 28,739,584 (avail = 56,132, bsize = 512, iosize = 131,072) statvfs("/zfs") = 7,357,333,504 (avail = 56,132, bsize = 131,072, frsize = 512) statfs("/tmpfs") = 67,104,768 (avail = 16,383, bsize = 4,096, iosize = 4,096) statvfs("/tmpfs") = 67,104,768 (avail = 16,383, bsize = 4,096, frsize = 4,096) statfs("/nfs") = 28,739,584 (avail = 56,132, bsize = 512, iosize = 65,536) statvfs("/nfs") = 3,678,666,752 (avail = 56,132, bsize = 65,536, frsize = 512)
And so --session-info for remote client is almost always wrong about free space in download directory.
