I'm running glusterfs on CentOS 6.6 two nodes, (the SSD (samsung 840 1TB x2) is RAID 0 on the HP DL380 G6) x2, and trimming is not enable on it by checking /dev/sdb1/xxxxx/discard_max_bytes=0. Do I still need trimming? Somehow my filesystem is fine with 35-30% free space and running very fast.
Thanks for any comment you may add.
