Bug ID: 1202292
Summary: quota: 'Usage crossed soft limit' not generated in the
log
Product: GlusterFS
Version: mainline
Component: quota
Assignee: bugs at gluster.org
Reporter: vmallika at redhat.com
CC: bugs at gluster.org, gluster-bugs at redhat.com
Sometimes Test-18/20 fails from: ./tests/bugs/quota/bug-1087198.t
Test-18
TEST grep -e "\"Usage crossed soft limit:.*used by /$QUOTA_LIMIT_DIR\"" --
$BRICK_LOG_DIR/*
Test-20
TEST grep -e "\"Usage crossed soft limit:.*used by /\"" -- $BRICK_LOG_DIR/*
Problem is. Consider below scenario in the quota xlator.
T1 - write with delta1 bytes on fd1
check_limit sees that delta1 bytes is not exceeding soft limit
T2 - write with delta2 bytes on fd1
check_limit sees that delta2 bytes is not exceeding soft limit
T3 - delta1 and delta2 bytes are written to the disk.
Here delta1 and delta2 are checked separately and do not exceed
limit, but they together exceed the limit which is not checked.
