* MFgraid/head:Alexander Motin2011-03-244-0/+368
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new RAID GEOM class, that is going to replace ataraid(4) in supporting various BIOS-based software RAIDs. Unlike ataraid(4) this implementation does not depend on legacy ata(4) subsystem and can be used with any disk drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4) with `options ATA_CAM`). To make code more readable and extensible, this implementation follows modular design, including core part and two sets of modules, implementing support for different metadata formats and RAID levels. Support for such popular metadata formats is now implemented: Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage. Such RAID levels are now supported: RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT. For any all of these RAID levels and metadata formats this class supports full cycle of volume operations: reading, writing, creation, deletion, disk removal and insertion, rebuilding, dirty shutdown detection and resynchronization, bad sector recovery, faulty disks tracking, hot-spare disks. For Intel and Promise formats there is support multiple volumes per disk set. Look graid(8) manual page for additional details.

| | | | | | | | | | | Make `geom XXX list` and `geom XXX status` outputs more consistent: Add -a options to print all geoms, not only ones with providers. Add -g option for `status` to report geom's names, not provider's. Make `status` by default report provider's status (if present), not geom's. Make `status` report consumer's statuses, not only "synchronized" field. Notes: svn path=/head/; revision=219969

| | | | | | | | | | | | | | | | | our info about worker processes if any of them was terminated in the meantime. This fixes the problem with 'hastctl status' running from a hook called on split-brain: 1. Secondary calls a hooks and terminates. 2. Hook asks for resource status via 'hastctl status'. 3. The main hastd handles the status request by sending it to the secondary worker who is already dead, but because signals weren't checked yet he doesn't know that and we get EPIPE.

* In hast.conf we define the other node's address in 'remote' variable.Pawel Jakub Dawidek2011-03-2114-36/+124
| | | | | | | | | | | | | | | | | | | | | This way we know how to connect to secondary node when we are primary. The same variable is used by the secondary node - it only accepts connections from the address stored in 'remote' variable. In cluster configurations it is common that each node has its individual IP address and there is one addtional shared IP address which is assigned to primary node. It seems it is possible that if the shared IP address is from the same network as the individual IP address it might be choosen by the kernel as a source address for connection with the secondary node. Such connection will be rejected by secondary, as it doesn't come from primary node individual IP. Add 'source' variable that allows to specify source IP address we want to bind to before connecting to the secondary node. MFC after: 1 week Notes: svn path=/head/; revision=219818
