Bug ID: 197356
Summary: mountlate is too fast for some iSCSI / UFS
configurations
Product: Base System
Version: 10.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: freebsd-bugs at FreeBSD.org
Reporter: prj at rootwyrm.com
In some scenarios, /etc/rc.d/mountlate is still too fast for late filesystems,
specifically observed in an iSCSI configuration. Relevant devices arrive just
slightly too late, which results in mountlate aborting and dropping to single
user.
/dev/ufs/osrc /prod/odev/src ufs rw,late 0 0
/dev/ufsid/54d3d4231491292f /opt/scratch ufs rw,late 0 0
Both of these entries failed due to mountlate successfully racing against
iscsictl. Rough estimate is that it's probably around 0.5s too quick.
No patch as the fix is really, really simple. Adding 'sleep 1' at line 24
(after 'err=0' before 'echo -n') in /etc/rc.d/mountlate fixes this problem with
no known side effects.
