If you help me,I will be happy. 5% space is reserved. This can be modified during formatting with mkfs.ext3 during format time or later with tune2fs command. From tune2fs's man: -m reserved-blocks-percentage Set the percentage of the filesystem which may only be allocated by privileged processes. Reserving some number of filesystem blocks for use by privileged processes is done to avoid filesystem fragmenta‐ tion, and to allow system daemons, such as syslogd(8), to continue to function correctly after non- privileged processes are prevented from writing to the filesystem. Normally, the default percentage of reserved blocks is 5%.
