Hello, I was testing the raid0 configuration for the iscsi device ( /dev/sdb and /dev/sdc). For writing a 512MB in a LAN environment it was taking 24 hrs. i was going through the source code of raid0.c and certain things doesn't made sense to me. 1> what role does the Hash bit play. 2>If my chunk size is 8 byte. Does that mean it will write 8 byte into device 0 and then into device 1. Is the write request to the disk in synchronous or asynchronous mode. 3> Is wite_disk_sb in md.c responsible for writing into disk??. Is fsync_dev responsible for synhronous write ??. If so can i change to asynchronous write.I will really appreciate if somebody can tell me what all routines I need to go through to figure out the functionality of raid0 behaviour.
