180 days, whichever comes first. Use tune2fs -c or -i to override.

#man tune2fs
ReplyDelete-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 fragmentation, 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%.
