deleted file using memory
 

Hi all
I am booting Linux from CF card. When I am deleting any file, file is deleted but memory not get free.
output of df -h
Filesystem Size Used Available Use% Mounted on
/dev/hda1 244.0M 231.6M 12.4M 95% /initrd/mnt/dev_ro1


How can I solve this problem?



Thanks & Regards

What version of Linux is this? To me the /initrd/mnt/dev_ro1
suspiciously looks like /dev_ReadOnly1 ... which would explain
the inability to delete stuff (maybe it copies stuff into RAM
and your deletion only takes place there?) ....

initrd often uses cramfs or romfs. These filesystems do not support deletion since they are special purpose filesystems, used when that is not usually a desired operation. The optimisations (size, simplicity, speed, compression capability and so on) gained by not implementing such functions are worth the limitation.
