03984e05a3 Rename mirror_device_fault_policy to mirror_image_fault policy 2010-01-06 13:27:06 +00:00
Mike Snitzer
7a8fa6aaab Add a [--poll {y|n}] flag to vgchange and lvchange to control whether 
the background polldaemon is allowed to start.  It can be used
standalone or in conjunction with --refresh or --available y.

Control over when the background polldaemon starts will be particularly
important for snapshot-merge of a root filesystem.

Dracut will be updated to activate all LVs with: --poll n

The lvm2-monitor initscript will start polling with: --poll y

NOTE: Because we currently have no way of knowing if a background
polldaemon is active for a given LV the following limitations exist and
have been deemed acceptable:
1) it is not possible to stop an active polldaemon; so the lvm2-monitor
   initscript doesn't stop running polldaemon(s)
2) redundant polldaemon instances will be started for all specified LVs
   if vgchange or lvchange are repeatedly used with '--poll y'

99a304bc17 Optionally abort on internal errors (and leverage this option in the 
testsuite). (This is showing a problem in the pvmove test for me, so I expect
the tests to start failing -- this needs to be fixed separately though.)

5800aa5c07 Do not allow creating mirrors of more than 8 images.

2aabcc1c1c Add devices/data_alignment_detection to lvm.conf. 
Adds 'data_alignment_detection' config option to the devices section of
lvm.conf.  If your kernel provides topology information in sysfs (linux
>= 2.6.31) for the Physical Volume, the start of data area will be
aligned on a multiple of the ’minimum_io_size’ or ’optimal_io_size’
exposed in sysfs.

minimum_io_size is used if optimal_io_size is undefined (0).  If both
md_chunk_alignment and data_alignment_detection are enabled the result
of data_alignment_detection is used.

57b660356e Add devices/data_alignment_offset_detection to lvm.conf. 
If the pvcreate --dataalignmentoffset option is not specified the start
of a PV's aligned data area will be shifted by the associated
'alignment_offset' exposed in sysfs (unless
devices/data_alignment_offset_detection is disabled in lvm.conf).

25497e2fa5 Fix confusing metadata syntax error messages. 
If there is syntax error in metadata, it now prints messages
like:
  Couldn't read 'start_extent' for segment 'extent_count'.
  Couldn't read all logical volumes for volume group vg_test.

The segment specification is wrong and confusing.

Patch fixes it by introducing "parent" member in config_node which
points to parent section and config_parent_name function, which
provides pointer to node section name.

Also it adds several LV references where possible.

25b733809a Merge with text format branch. 
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.
