[LU-5680] sanity-hsm uses /etc/motd (which is probably of size 0)

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.12.1
• Affects Version/s: Lustre 2.11.0, Lustre 2.10.4
• Labels: hsm ubuntu
• Severity: 3
• Assignee: James Nunez (Inactive)
• Reporter: John Hammond

Description

In various tests sanity-hsm copies /etc/hosts, /etc/passwd, or /etc/modt for use as the test file. /etc/motd is likely of size 0 and may defeat the use of bandwidth control for timing. Uses of /etc/* should be replaced with a generated files of known suitable size. We should also add explicit tests using files of size 0.

There are still a lot of place in sanity-hsm where /etc/{passwd,hosts} are used. Maybe this ticket should be reopened.

Patch http://review.whamcloud.com/14021 replaces all uses of /etc/* with creation of a small file of known size. A second patch will be created to add archiving of zero byte files to sanity-hsm.
