* Remove an accidental #include.Greg Lehey2003-05-051-8/+30
| | | | | | | | | | | Maintain sector sizes for all objects, not just for drives. Some of this could do with improvement: in particular, we get an error if the components of an object have different sector sizes. Clean up some comments. Notes: svn path=/head/; revision=114717

* vinum_scandisk: Make sure the config is locked before we mess aroundGreg Lehey2003-05-051-15/+22
| | | | | | | | | | | | | | | | | | | | | | | | with it. Finally implement read policies. The previous "implementation" didn't work because it referred to plexes which were almost invariably when referred to. Instead, deprecate the "prefer" keyword for volumes (though it's still there for the moment) and add a keyword "preferred" to the plex definition. The relationship is like this: Old: vol foo ... prefer foo.p3 New: plex foo.p3 volume foo preferred print_config: Print "preferred" where appropriate. No longer print "prefer" on volume config entries. Notes: svn path=/head/; revision=114695

The super devices are high-order volume numbers. This gives vastly more potential volumes (4 million instead of 256). As a result of the minor number changes, split out the superdevice handling into a separate function, vinum_super_ioctl. This was most of the code of vinumioctl. attachobject: Improve error checking.

* Centralize the devstat handling for all GEOM disk device driversPoul-Henning Kamp2003-03-081-1/+0

* - Add an interlock argument to BUF_LOCK and BUF_TIMELOCK.Jeff Roberson2003-02-251-2/+2
| | | | | | | | | | | | | - Remove the buftimelock mutex and acquire the buf's interlock to protect these fields instead. - Hold the vnode interlock while locking bufs on the clean/dirty queues. This reduces some cases from one BUF_LOCK with a LK_NOWAIT and another BUF_LOCK with a LK_TIMEFAIL to a single lock. Reviewed by: arch, mckusick Notes: svn path=/head/; revision=111463

* Finally make vinum ready for the root filesystem in FreeBSD 5.x. (AJoerg Wunsch2003-02-053-22/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | similar patch has been in 4.x for a while, but is more hacky there.) For this to work, vinum has to be loaded early (e. g. from boot/loader), for obvious reasons. If the kernel env variable (aka. loader variable) "vinum.autostart" is set, vinum then asks the sysctl kern.disks for all available disks in the system, and scans them for possible vinum headers. For statically compiled kernels, this behaviour can be obtained even without boot/loader by using "options VINUM_AUTOSTART" (though this is not the recommended way). Alternatively, the 4.x way to specify "vinum.drives" is also supported. No further hacks (like the 4.x "vinum.root" variable) are needed, since in 5.x, mountroot() asks back at the drivers to have them resolve the name of the root FS into a dev_t (using the dev_clone eventhandler). (The MFC reminder below is for a partial MFC for vinum.autostart, the rest is already there in 4.x.) Timed out on: grog MFC after: 2 weeks Notes: svn path=/head/; revision=110417
