Hye, I still try to access application side I/O size on a ZFS file system.
( example : if /var/zfs_fs is a ZFS file system /var/zfs_fs:# dd if=/dev/urandom of=file bs=4k count=100000000000000 i try to get an information simple as execname == "dd" block_size = 4096 in order to trace a specific application I/O profile I've tried with both "fbt::arc_access, fbt::arc_write, fbt::arc_buf_evict, fbt::arc_change_state, fbt::zio_create, ...", but i can't retrieve this information. Some times, block_size doesn't match 4k (e.g 128k, ..., or 0 with the zio_create probe) Some times, execname is "sched" and hide the application name wich initiate the I/O. I've read a lot of the ZFS ans ARC source code, but can't find any DTrace probe that provides me those informations. Please, need some Help R. -- This message posted from opensolaris.org
