We are doing incremental backup with use of hard links the initial size was 10 TB and we added 1 TB weekly .
du -hs week2 reports 11 TB; it is ok as inode are same and
du considers it to create disk usage find with it ..
but when we do
/backup (40TB) volume it is reporting backup1 (10T)+week2(11T)+week3(12T) = 33 TB --
this is bit critical as
df suspects that volume is growing fast (which is not since it only adds 1TB per week) and we are getting alarms about space ...
Is there any way we can tell
df not to count hard links ? or any other command to find the exact free space in volume?
