pjd 2006-03-13 01:03:18 UTC FreeBSD src repository Modified files: sys/geom/raid3 g_raid3.c g_raid3.h g_raid3_ctl.c Log: - Reimplement I/O data allocation to prevent deadlocks. Submitted by: green - Speed up synchronization process by using configurable number of I/O requests in parallel. + Add kern.geom.raid3.sync_requests tunable which defines how many parallel I/O requests should be used. + Retire kern.geom.raid3.reqs_per_sync and kern.geom.raid3.syncs_per_sec sysctls. - Fix race between regular and synchronization requests. - Reimplement raid3's data synchronization - do not use the topology lock for this purpose, as it may case deadlocks. - Stop synchronization from pre-sync hook. - Fix some other minor issues. Tested by: Mike Tancsa <mike@sentex.net> MFC after: 3 days Revision Changes Path 1.55 +540 -272 src/sys/geom/raid3/g_raid3.c 1.16 +39 -8 src/sys/geom/raid3/g_raid3.h 1.14 +93 -72 src/sys/geom/raid3/g_raid3_ctl.c
