system::onDiskAtime

The atime inode field in IBRIX can be accessed as the system::onDiskAtime attribute from the

API. This field represents different concepts in the lifetime of a WORM/retained file, and it often

represents a concept other than the time of the file’s last access, which is why the field was named

onDiskAtime rather than (for example) lastAccessedTime. (See “Retention properties

assignment” (page 172) for a description of this life cycle).

• Before a file is retained, whether WORM state or not, atime represents the last accessed time,

as long as the file system is mounted with the non-default atime option. If the file system is

mounted with the default noatime option, atime is the file’s creation time, and never changes

unless the file is retained (see the second bullet). See “Creating and mounting file systems”

(page 13) for more information about mount options.

• While a file is in the retained state, atime represents the retention expiration time.

• After retention expires, atime represents the time at which the file was first retained (even if

the file has been retained and expired more than once), and it never changes again, unless

the file is re-retained (see the second bullet).

If you have enabled the auditing of file read events, then reads are logged in the audit logs.

However, file reads do not update system::onDiskAtime even if the file reads are being

audited. All other file accesses modify the system::onDiskAtime with the current value of

atime. Therefore, before the file is retained (first bullet), if the file system is mounted with the

atime option, system::onDiskAtime represents the last accessed time before the last file

modification, not necessarily the current atime or the last accessed time. To list all read accesses

to a file, use the ibrix_audit_reports command as described in the CLI Reference Guide
