| | | | | | | | | | | | | | | | | | defined by the SNIA Common RAID Disk Data Format Specification v2.0. Supports multiple volumes per array and multiple partitions per disk. Supports standard big-endian and Adaptec's little-endian byte ordering. Supports all single-layer RAID levels. Dual-layer RAID levels except RAID10 are not supported now because of GEOM RAID design limitations. Some work is still to be done, but the present code already manages basic interoperation with RAID BIOS of the Adaptec 1430SA SATA RAID controller. MFC after: 1 month Sponsored by: iXsystems, Inc.

* Some improvements to GEOM MULTIPATH:Alexander Motin2012-04-182-8/+45
| | | | | | | | | | | | | | | | | | | - Implement "configure" command to allow switching operation mode of running device on-fly without destroying and recreation. - Implement Active/Read mode as hybrid of Active/Active and Active/Passive. In this mode all paths not marked FAIL may handle reads same time, but unlike Active/Active only one path handles write requests at any point in time. It allows to closer follow original write request order if above layers need it for data consistency (not waiting for requisite write completion before sending dependent write). - Hide duplicate messages about device status change. - Remove periodic thread wake up with 10Hz rate.

* Major GEOM MULTIPATH class rewrite:Alexander Motin2011-11-122-98/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Improved locking and destruction process to fix crashes. - Improved "automatic" configuration method to make it consistent and safe by reading metadata back from all specified paths after writing to one. - Added provider size check to reduce chance of ordering conflict with other GEOM classes. - Added "manual" configuration method without using on-disk metadata. - Added "add" and "remove" commands to allow manage paths manually. - Failed paths are no longer dropped from geom, but only marked as FAIL and excluded from I/O operations. - Automatically restore failed paths when all others paths are marked as failed, for example, because of device-caused (not transport) errors. - Added "fail" and "restore" commands to manually control FAIL flag. - geom is now destroyed on last path disconnection. - Added optional Active/Active mode support. Unlike Active/Passive mode, load evenly distributed between all working paths. If supported by the device, it allows to significantly improve performance, utilizing bandwidth of all paths. It is controlled by -A option during creation. Disabled by default now. - Improved `status` and `list` commands output. Sponsored by: iXsystems, inc.
