Not every file system or device is mounted during boot time. On servers it sometimes happens that a server log might already being rotated.

How to find out when a mounted file system or device was mounted?

Note: Answers should be general, rather than specific to a particular file system. But specific file system answers would be better than nothing.


tune2fs -l devname will give you the last mount date for local ext? partitions.

  • I would be ideal if the tool could also do this for cifs mounts etc – frlan Jan 5 '16 at 22:55
