File system concepts (df command)
- by mkab
I'm finding it difficult to understand some stuffs about the df command. Suppose I type df and I have the following output
Filesystem 1k-blocks Used Avail Capacity Mounted on
/dev/da0s1 some number some number number percentage /win
/dev/da0s2 some number some number number percentage /win/home
/dev/da0s3a some number some number number percentage /
devfs some number some number number percentage /dev
/dev/da0s3g some number some number number percentage /local
/dev/da0s3h some number some number -number 102% /reste
/dev/da0s3d some number some number number percentage /tmp
/dev/da1s3f some number some number number percentage /usr
/dev/da1s3e some number some number number percentage /var
/dev/da1s1a some number some number number percentage /public
Are the answers to the following questions correct?
How many physical drives do I have?
Ans: 2. da0s1 and da1s1
How many physical partitions on each disk?
Ans: 8 for da0s1 and 1 for da1s1
How many BSD partition on each physical partition
Ans: Impossible to determine. We have to use the -T to determine its type
How is it possible for the file system /dev/da0s3h filled at 102%? And where is this overflowed data written?Ans: I have no idea for this one
Thanks.
