If this variable is not set, NFS version 2 is used. The ZFS on-disk format has been updated to version The ZFS metaslab code has been updated. The ZFS now supports offlining of log devices. They include caching of ACL permission checks, faster handling of stat 2 , mitigation of mutex lock contention. The related OpenSolaris Bug IDs are , , , , , , , , , , and The default value of vfs. Various bugs in the ZFS subsystem have been fixed.
The arp 8 utility has been improved. It now runs faster even when a single interface has a number of aliases. A bug in the b64decode 1 utility that prevented an -r option from handling arbitrary breaks in a base64 encoded string has been fixed. The calendar 1 utility now supports repeating events which span multiple years, lunar events, and solar events. The dhclient 8 utility now reports a reason for exiting and the second period in which the dhclient 8 ignores routing messages has been changed to start just after dhclient-script starts instead of just after it finished.
This change fixes a symptom that dhclient 8 silently exits under a certain condition. Userland support for the dtrace 1 subsystem has been added. This allows inspection of userland software itself and its correlation with the kernel, thus allowing a much better picture of what exactly is going on behind the scenes. The dtruss 1 utility has been added and the libproc library has been updated to support the facility. The du 1 utility now supports a -t threshold option to display entries that exceeds the value of threshold.
If the value is negative, it displays entries with a value less than the absolute value of threshold. The fdisk 8 utility now supports partitions which are provided by gjournal 8 or geli 8 GEOM classes. The gcore 1 utility now supports an -f flag which forces a full dump of all the segments except for the malformed ones. The geli 8 utility now supports resize subcommand to resize encrypted file systems after growing it. The geli 8 utility now supports suspend and resume subcommands.
For more information, see geli 8 manual page. The geli 8 utility now checks the metadata provider size strictly. If the check fails, the provider is not attached. A new option -f can override this behavior. The geli 8 utility now supports -J newpassfile and -j oldpassfile options for loading passphrase from a file.
The gpart 8 utility now supports a resize command to resize partitions for all schemes but EBR. The gpart 8 utility now supports backup and restore subcommands to backup partition tables and restore them.
The gpart 8 utility now supports an -F option for the destroy subcommand. This option forces destroying of the partition table even if it is not empty. The gpart 8 utility now supports a recover subcommand for GPT partition tables. A corrupted GPT is now marked when the following three types of corruption:[ r ].
Changes to the corrupted GPT table are not allowed except for destroy and recover subcommands. The attribute keywords in the command line are bootme , bootonce , and bootfailed respectively. An issue in the newfs 8 utility has been fixed. A UFS1 file system created with 64KB blocksize was incorrectly recognized as one with a broken superblock.
For example, a file system created by newfs -U -O 1 -b -f could lead to this symptom. The ifconfig 8 utility now check an invalid CIDR subnet notation more strictly. It wrongly accepted An accuracy issue in the jn 3 and jnf 3 functions in libm has been fixed. Incorrect behaviors in stuttering sequences and reverse ranges in the jot 1 utility have been fixed. The tar 1 utility now supports a blocksize which is up to 4MB in the -b blocksize option. A bug in the lpr 1 utility that prevented it from working with some files on a ZFS file system has been fixed.
The -p option in the mount 8 utility now displays the rw mount option correctly as in the fstab 5 format. The ncal 1 utility has been updated. The option -b has been replaced with -C and -B number. Options -3 to show previous, current and next month, and -A number to show months after current month have been added. The newsyslog 8 utility now supports an -S pidfile option to override the default syslogd 8 PID file.
Globbing in the file name and circular dependency detection are supported. For more details, see the newsyslog. The ntpd 8 utility is now compiled with shared memory reference clock driver. An off-by-one error in the pax 1 utility when ustar file name is too long has been fixed. The pkill 1 utility now supports an -l option like the kill 1 utility does. The pmcstat 8 utility now supports a file and a network socket as a top source. A new option -O filename specifies to send log output to filename , and another new option -R filename specifies to receive events from filename.
For a socket, the filename is in a form of ipaddr:port. This allows top monitoring over TCP on a system with no local symbols, for example. The pom 6 utility now supports a -p flag to print only the percentage. The powerd 8 utility now supports an -m freq and -M freq to control the minimum and maximum frequency, respectively. The ruptime 1 utility now displays hostnames longer than 12 characters. A behavior of the sh 1 program when an -u option is specified has been changed.
A bug in the sh 1 program has been fixed. A SIGINT signal is now passed through from a child process if the shell is interactive and the job control is enabled. For example, aborting sleep 1 command by Ctrl-C no longer display ok in the following command line:[ r ]. The sh 1 program now supports a bg command consisting solely of redirections. For example:[ r ]. The tftp 1 and tftpd 8 utilities have been improved for better interoperability and they now support RFC , , , , and The uname 1 utility now supports an -o flag as a synonym for the -s flag for compatibility with other systems.
Bugs in vi 1 utility have been fixed. This kind of process termination happens in a swap-intensive workload. The set sharenfs command in the zfs 8 utility now supports sec option. A periodic script for zfs scrub has been added.
Most devices that can be found in or are compatible with ia64 machines are fully supported. The notable exception is the VGA console. As such syscons 4 can not be enabled and the use of a serial console is required.
High-resolution mode is not supported. For background information on the various hardware designs see the Sun System Handbook. If you have a system that is not listed here, it may not have been tested with FreeBSD 8. The following systems are partially supported by FreeBSD. In particular the fibre channel controllers in SBus-based systems are not supported.
Starting with 7. This section describes the devices currently known to be supported by FreeBSD. Other configurations may also work, but simply have not been tested yet. Feedback, updates, and corrections to this list are encouraged. Where possible, the drivers applicable to each device or class of devices is listed. If the driver in question has a manual page in the FreeBSD base distribution most should , it is referenced here.
Information on specific models of supported devices, controllers, etc. This means that some devices, which are supported by multiple drivers, may appear multiple times. Controllers supported by the amr 4 driver include:. Note: [amd64, i] Booting from these controllers is supported. EISA adapters are not supported. Cards supported by the isp 4 driver include:. All major firmware revisions 2. The following controllers are supported by the mpt 4 driver:.
The Ultra SCSI controller chips supported by the mpt 4 driver can be found onboard on many systems including:. The Integrated Raid Mirroring available for these controllers is poorly supported at best. The Fibre Channel controller chipset are supported by a broad variety of speeds and systems. This driver also supports target mode for Fibre Channel cards. This support may be enabled by setting the desired role of the core via the LSI Logic firmware utility that establishes what roles the card can take on - no separate compilation is required.
The SCSI controllers supported by sym 4 can be either embedded on a motherboard, or on one of the following add-on boards:. The ale 4 device driver provides support for the following Ethernet controllers:. The chips supported by the cas 4 driver are:. The following add-on cards are known to work with the cas 4 driver at this time:.
The dc 4 driver provides support for the following chipsets:. The following NICs are known to work with the dc 4 driver at this time:. The ed 4 driver does not support the following Ethernet NICs:. The em 4 driver supports Gigabit Ethernet adapters based on the Intel , ER, PI, , , , , , EB, GB, , , , , and controller chips:.
