<div>Having our metadata NSDs fill up was what prompted this exercise, but space was previously feed up on those by switching them from metadata+data to metadataOnly and using a policy to migrate files out of that pool. So these now have about 30% free space (more if you include fragmented space). The restripe attempt is just to make a final move of any remaining data off those devices. All the NSDs now have free space on them.</div>
<div> </div>
<div>df -i shows inode usage at about 84%, so plenty of free inodes for the filesystem as a whole.</div>
<div> </div>
<div>We did have old .quota files laying around but removing them didn't have any impact. </div>
<div> </div>
<div>mmlsfileset fs -L -i is taking a while to complete, I'll let it simmer while getting to work.</div>
<div> </div>
<div>mmrepquota does show about a half-dozen filesets that have hit their quota for space (we don't set quotas on inodes). Once I'm settled in this morning I'll try giving them a little extra space and see what happens.</div>
