* Add the Clang specific -Wmissing-variable-declarations to WARNS=6.ed2013-04-191-0/+1
| | | | | | | | | | | | | This compiler flag enforces that that people either mark variables static or use an external declarations for the variable, similar to how -Wmissing-prototypes works for functions. Due to the fact that Yacc/Lex generate code that cannot trivially be changed to not warn because of this (lots of yy* variables), add a NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this specific compiler warning.

Number of BIO_WRITEs and activemap updates are especially interesting, because if those two are too close to each other, it means that your workload needs bigger number of dirty extents. Activemap should be updated as rarely as possible. MFC after: 1 week
* Currently we are unable to use capsicum for the primary worker process,pjd2011-05-141-1/+1
| | | | | | | | | | | | | | | | | because we need to do ioctl(2)s, which are not permitted in the capability mode. What we do now is to chroot(2) to /var/empty, which restricts access to file system name space and we drop privileges to hast user and hast group. This still allows to access to other name spaces, like list of processes, network and sysvipc. To address that, use jail(2) instead of chroot(2). Using jail(2) will restrict access to process table, network (we use ip-less jails) and sysvipc (if security.jail.sysvipc_allowed is turned off). This provides much better separation.

| | | | | | | | | We can use capsicum for secondary worker processes and hastctl. When working as primary we drop privileges using chroot+setgid+setuid still as we need to send ioctl(2)s to ggate device, for which capsicum doesn't allow (yet). X-MFC after: capsicum is merged to stable/8

* Please welcome HAST - Highly Avalable Storage.pjd2010-02-183-0/+779
HAST allows to transparently store data on two physically separated machines connected over the TCP/IP network. HAST works in Primary-Secondary (Master-Backup, Master-Slave) configuration, which means that only one of the cluster nodes can be active at any given time. Only Primary node is able to handle I/O requests to HAST-managed devices. Currently HAST is limited to two cluster nodes in total. HAST operates on block level - it provides disk-like devices in /dev/hast/ directory for use by file systems and/or applications. Working on block level makes it transparent for file systems and applications. There in no difference between using HAST-provided device and raw disk, partition, etc. All of them are just regular GEOM providers in FreeBSD. For more information please consult hastd(8), hastctl(8) and hast.conf(5) manual pages, as well as http://wiki.FreeBSD.org/HAST.
