I built HA iSCSI targets with ocfs2+dual primary.(Ubuntu 13.04) Each node has SSD raid with mdadm level0. few days later, ocfs2 became frozen sometimes. I figured out that it happens without TRIM. But, I couldn't TRIM ssd raid because ocfs2 only supports offline TRIM(fstrim) and drbd 8.4.4 only supports online TRIM(discard). Then, HOW CAN I TRIM SSDs on DRBD+OCFS2?
