In my test cluster in systems with similar RAID cards, I create single-disk RAID-0 volumes. That does the trick.

Those are very good end cards , but do not support jbod . They support raid 0, 1, 5, 6, 10, 50, 60 . lspci shows them as: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05) The firmware Dell uses on the card does not support jbod. My question is how can this be best used for Ceph? Or should it not be used? -------------- next part -------------- An HTML attachment was scrubbed...
