df -k command shows duplicate information in solaris machine, How to get the exact

Question

I am using df -k command to get the total size of the disk space for solaris machine.

But, i am getting duplicate info like listing disk space for every user under the same partion.

Here user spaces of soluser1,2,3,5 were located under /export. It will give wrong result if i sum up all those values available under Available field.

Whereas in linux, i can get the correct space using the same command. How to get the correct disk space in solaris, please advice.

Answer 1

You are getting the correct results from df -k. You only get the wrong results if you sum them -- so don't sum them. That doesn't make sense anyway. It makes no sense to sum things that partially or fully overlap.

Answer 2

Solaris is using the ZFS filesystem which allows filesystems to share free space. Use the 'zfs list' command or the "zpool info" command to show more information about ZFS filesystems and pools.
