Add GEOM module compilation shims. 2003-05-31 18:36:41 +00:00			`# $FreeBSD$`

Don't recurse into geom_apple and geom_gpt. They have been moved into the g_part framework. 2007-02-07 21:37:02 +00:00			`SUBDIR= geom_bde \`

A GEOM cache can speed up read performance by sending fixed size read requests to its consumer. It has been developed to address the problem of a horrible read performance of a 64k blocksize FS residing on a RAID3 array with 8 data components, where a single disk component would only get 8k read requests, thus effectively killing disk performance under high load. Documentation will be provided later. I'd like to thank Vsevolod Lobko for his bright ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug. 2006-10-06 08:27:07 +00:00			`geom_cache \`

Add "GEOM_FOX", a class which detects and selects between multiple redundant paths to the same device. This class reacts to a label in the first sector of the device, which is created the following way: # "0123456789abcdef012345..." # "<----magic-----><-id-...> echo "GEOM::FOX someid" \| dd of=/dev/da0 conv=sync NB: Since the fact that multiple disk devices are in fact the same device is not known to GEOM, the geom taste/spoil process cannot fully catch all corner cases and this module can therefore be confused if you do the right wrong things. NB: The disk level drivers need to do the right thing for this to be useful, and that is not by definition currently the case. 2003-06-18 09:29:28 +00:00			`geom_fox \`

Introduce GEOM_LABEL class. This class is used for detecting volume labels on file systems: UFS, MSDOSFS (FAT12, FAT16, FAT32) and ISO9660. It also provide native labelization (there is no need for file system). g_label_ufs.c is based on geom_vol_ffs from Gordon Tetlow. g_label_msdos.c and g_label_iso9660.c are probably hacks, I just found where volume labels are stored and I use those offsets here, but with this class it should be easy to do it as it should be done by someone who know how. Implementing volume labels detection for other file systems also should be trivial. New providers are created in those directories: /dev/ufs/ (UFS1, UFS2) /dev/msdosfs/ (FAT12, FAT16, FAT32) /dev/iso9660/ (ISO9660) /dev/label/ (native labels, configured with glabel(8)) Manual page cleanups and some comments inside were submitted by Simon L. Nielsen, who was, as always, very helpful. Thanks! 2004-07-02 19:40:36 +00:00			`geom_label \`

Add gmountver, disk mount verification GEOM class. Note that due to e.g. write throttling ('wdrain'), it can stall all the disk I/O instead of just the device it's configured for. Using it for removable media is therefore not a good idea. Reviewed by: pjd (earlier version) 2010-01-16 09:52:49 +00:00			`geom_mountver \`
First cut at GEOM based multipath. This is an active/passive{/passive...} arrangement that has no intrinsic internal knowledge of whether devices it is given are truly multipath devices. As such, this is a simplistic approach, but still a useful one. The basic approach is to (at present- this will change soon) use camcontrol to find likely identical devices and and label the trailing sector of the first one. This label contains both a full UUID and a name. The name is what is presented in /dev/multipath, but the UUID is used as a true distinguishor at g_taste time, thus making sure we don't have chaos on a shared SAN where everyone names their data multipath as "Fred". The first of N identical devices (and N may be 1!) becomes the active path until a BIO request is failed with EIO or ENXIO. When this occurs, the active disk is ripped away and the next in a list is picked to (retry and) continue with. During g_taste events new disks that meet the match criteria for existing multipath geoms get added to the tail end of the list. Thus, this active/passive setup actually does work for devices which go away and come back, as do (now) mpt(4) and isp(4) SAN based disks. There is still a lot to do to improve this- like about 5 of the 12 recommendations I've received about it, but it's been functional enough for a while that it deserves a broader test base.

Bring in geom_sched, support for scheduling disk I/O requests in a device independent manner. Also include an example anticipatory scheduler, gsched_rr, which gives very nice performance improvements in presence of competing random access patterns. This is joint work with Fabio Checconi, developed last year and presented at BSDCan 2009.
