<p class="MsoNormal">Hi ANS,<o:p></o:p></p>

<p class="MsoNormal">About the soft limits and not receiving any warning or notification when the soft quota is reached, this would be the expected behavior. The soft quota is used together with the grace period to give some “extra” time to the user to remove
inodes/blocks, as per the Lustre Operations Manual:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-family:Courier">Soft limit -- The grace timer is started once the soft limit is exceeded. At this point, the user/group/project can still allocate block/inode. When the grace time expires and if the user is still above
the soft limit, the soft limit becomes a hard limit and the user/group/project can't allocate any new block/inode any more. The user/group/project should then delete files to be under the soft limit. The soft limit MUST be smaller than the hard limit. If the
soft limit is not needed, it should be set to zero (0).<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m not aware of any warnings triggered by Lustre when the soft quota is reached, though that would be interesting to have. I know some people using external tools to monitor Lustre quotas and trigger warnings or similar for users exceeding
their soft quota.<o:p></o:p></p>
