XFS and nobarrier with SSDs

[Georg Schönberger]

Hi folks!

We are using a lot of SSDs in our Ceph clusters with XFS. Our SSDs have Power Loss Protection
via capacitors, so is it safe in all cases to run XFS with nobarrier on them? Or is there indeed
a need for a specific I/O scheduler?

I have found a recent discussion on the Ceph mailing list, anyone from XFS that can help us?
