[ANNOUNCE] multipath-tools-0.2.1

[christophe.varoqui]

Hello,

here goes multipath-tools-0.2.1

This is a fairly big update which address all the problems reported so far and
includes patchs from a greater number of testers. I'm quite happy to see it
mostly works for a wide variety of hardware (server arch and storage).
Anyway, it still needs more beating. Specificaly on EMC hardware, to which I
don't have access.

Changelog for this release :

        * [multipath] add a flag to inihibit the final SIGHUP to
          multipathd. Needed to avoid recursion with the correction
          below
        * [multipathd] devmap event now triggers a multipath exec
          in addition to the usual updatepaths()
        * [multipathd] move checkers from sg_io on BLK onto CHR
          readsector0 goes from read to sg_read
        * [multipathd] rely on sysfs for failedpaths enum and no
          longer on the device mapper
        * [multipathd] convert get_lun_strings from ioctl to sysfs
          so we can benefit from strings persistency for failed
          paths
        * [multipath] readconfig() to take only 8 char from vendor
          string (ake)
        * [multipath] remove unecessery and wrong getuid == NULL
          check from devinfo() (ake)
        * [multipathd] make readsector0 open path O_DIRECT
        * [multipathd] sizeof(path) -> sizeof(struct path) (MikeC)
        * [Makefile] don't try to install and uninstall libs
        * [devmap_name] kill the wrong trailing '\n'
          (Mike Christie)
        * [kpartx] works with device nodes outside /dev
        * [kpartx] correctly display the delimiter in partition
          name outputs

[ANNOUNCE] multipath-tools-0.2.2

[christophe.varoqui]

Hello,

here goes multipath-tools-0.2.2

Major changes are :
1) get a real parser. so update the config file with provided sample
2) get rid of most fixed-size arrays in favor of resizable vectors

All in all, the code base now seems pretty sane.

Changelog for this release :

2004-06-07 multipath-tools-0.2.2
        * [multipath] leave out 2.4 compat code. Is there
          interest anyway ?
        * [multipath] convert all_paths table to vector api.
          Rename to pathvec. Get rid of max_devs
        * [multipath] convert mp table to vector api
        * convert blacklist to vector api
        * 2.6.7-rc? adds _user annotations to scsi/sg.h, causing
          compilation breakage. Add a "#define _user" in all
          sg_include.h (and remove cruft)
        * merge a real parser (from keepalived) courtesy of 
          Alexandre Cassen. Now multipath and multipathd share a
          config file. This comes with a nice vector lib.
        * devnode blacklist moved from hardcoded to config file
        * Guy Coates noted -O2 CFLAGS lead to multipathd crashes
          on IA64. Remove the needless optimisation for now.

Hello,

here goes multipath-tools-0.2.3

Changelog for this release :
 
2004-06-14 multipath-tools-0.2.3
        * [multipath] group_by_serial try to be smart with LUN
	  balancing across controlers (for STK / LSI) :
	  1st multipath : 1st pg made of paths through 1st controler
	  2nd multipath : 1st pg made of paths through 2nd controler
	  3rd multipath : 1st pg made of paths through 1st controler
	  ...
	* [multipath] drop .pindex[] in struct multipath in favor
	  of a *paths vector : much cleaner
	* [multipath] fix group_by_serial pgpolicy broken by
	  vectorisation in 0.2.2
	* add a StorageTek and 2 SUN arrays in the sample multipath.conf
	* [multipathd] strcmp fix from 
	* [multipathd] convert to vector api
	* [multipathd] add a configfile option for path checking
	  interval. See sample configfile for synthax.

Changelog for this release :
 
2004-06-28 multipath-tools-0.2.4
        * [multipathd] break free from system's libsysfs for now
          as it is not that common these days
        * [multipath] introduce per LUN policies in the config
          file : path_grouping_policy, path_selector and
          path_selector_args are supported.
          See updated sample config file.

        * [multipath] default path selector override in config file
        * [multipath] don't play with strings in pgpolicies, leave

        * [multipath] strcmp fix (Franck Denis)

[ANNOUNCE] multipath-tools-0.2.6

[christophe varoqui]

Hello,
here goes multipath-tools-0.2.6
It's a really big feature update.
I hope I'll get feedback on the new features :

1) system-disk-on-SAN corner case treated with private namespace and
ramfs for callback programs. Next release I'll move the mknod to the
ramfs too by binding the ramfs to /tmp so scsi_id's mknod will have the
safety net too. See prepare_namespace() in main.c for review.

2) multipath config tool now get path id from callback proggys.
/bin/scsi_id by default. The tools now rely heavily on callbacks, so I'd
like to have insights about how to treat the out-of-memory case with
regard to these execv(). I'm also pondering ripping off the
get_evpd_wiid() fallback : does someone care ?

Finally note you *need* to update your config file. Not because I want
you to ackowledge to huge work put into reformatting and commenting, but
simply because the synthax has changed.

Changelog for this release :
        * [multipathd] implement the system-disk-on-SAN safety net
        * [multipathd] add exit_daemon() wrapper function
        * [multipathd] mlockall() all daemon threads
        * [multipath] fix a bug in the mp_iopolicy_handler that kept
          the iopolicy per LUN override from working
        * [multipath] display the tur bit value in print_path
          as requested by SUN
        * try to open /$udev/reverse/$major:$minor before falling back
          to mknod
        * add "udev_dir" to the defaults block in the config file
        * merge "daemon" & "device_maps" config blocks into a new
          "defaults" block
        * [multipath] properly comment the config file
        * [multipath] generalize the dbg() macro usage
          Makefile now has a DEBUG flag
        * [multipath] move to callout based WWID fetching. Default to
          scsi_id callout. I merged execute_program from udev for that
          (so credit goes to GregKH)
        * [multipath] get rid of "devnodes in /dev" assumption
          ie move to "maj:min" device mapper target synthax
