I am using drbd-0.7 with ext3-Filesystem (data=journal). Samba, NFS and Sybase SQL-Anywhere are running fine and fast. There are no lost (commited) Transactions of Sybase SQL when resetting the primary node. I have a performance problem with DRBD and Informix Dynamic Server 9.40. Informix Server opens its database files with O_SYNC in case of normal files, so writes a very slow. Is it possible to use /dev/nbX as RAW-Device? Then Informix will open without O_SYNC. Or is ist possible to prevent O_SYNC without touching Informix-Server? Best regards Thomas
