<div>Hello,</div>
<div> </div>
<div>We’ve recently noticed that one of our file system is runnig out of free space :</div>
<div>df -k</div>
<div>Filesystem 1K-blocks Used Available Use% Mounted on</div>
<div>/dev/drbd1 61925464 54821544 3958292 94% /xxx</div>
<div> </div>
<div>Having a look with ‘du’ shows, that only 35GB are used.</div>
<div>When I mounted that file system on the secondary node, all values are okay:</div>
<div>/dev/drbd1 61925464 34424544 24355292 59% /xxx</div>
<div> </div>
<div>What ist he reason for the difference of 20GB? (Activity log or other meta data?) And what can I do now to get free space back?</div>
<div> </div>
<div>Output of /prod/drbd on primary node (the one with the size problem) :</div>
<div>version: 8.4.1 (api:1/proto:86-100)</div>
