<div>Last time we had full OSTs that didn't look full it was due to running out of inodes because of a user who had tens of millions of files, all with a high stripe count. So "lfs df" reported heaps of space but "lfs df -i" showed the full devices. Might be
worth a look.</div>

<div dir="auto">Dear All,
<div dir="auto">We are running lustre 2.7.x in our cluster, which was running stable for few years. Suddenly a bug got triggered and basic copy command also fails with message like no space left on device. </div>
<div dir="auto">We were told to upgrade to lustre 2.10. Could we know: </div>
<div dir="auto"><br>
</div>
<div dir="auto">1. If there is any simpler work around available, as we want to avoid upgrade. Upgrade can be complex process.</div>
<div dir="auto"><br>
</div>
<div dir="auto">2. If upgrade is unavoidable, what is way to move from 2.7.x to 2.10 ?</div>
<div dir="auto"><br>

<div dir="auto">Thanks</div>
