No, not yet. I had those bad experiences with xfs_fsr on a ck patchset patched kernel and after this I didn't try again. Its pretty sure that my file content corruption issues was related to the ck patchset as I was not able to reproduce it with a CFS or mainline kernel. But still I have been reluctant. I think, I give it a try after I made my backups. > I have a shell script that runs in my 'cron.daily' that has two > lines: > ---- > #!/bin/bash > ionice -c 3 /usr/sbin/xfs_fsr & > ------- > > I've never noticed fragmentation above 1% on my disks...but your > mileage may vary ....
