relatime
and noatime
¶Filesystems usually feature access, creation, and modification time tracking for their folders and files. These times are updated by the operating system, and later written to disk, increasing disk access.
Modification and creation times are no big deal, but access times can carry a strong performance penalty, given read-only access is access. These access time updates can, over time, lead to missed performance on the table, and shorter lifespans for drives.
In order to mitigate this, Ironclad allows filesystems to be mounted
relatime
and noatime
. relatime
will make it so access
times are only updated if the modify time is greater, making it so only one
access post-modification is tracked. noatime
will not update access
times at all.
These flags can be applied on mount. mount/umount.
