Try to distinguish between the case of using interactive shell and non
interactive running - different combinations of '-y' and '-p' option
needs to be used for fsck.
Update the way how fsadm detects mounted filesystem.
With udev /dev/dm-XXX paths are now returned - but mount or /proc/mounts
prints names in form of /dev/mapper/vg-lv - so the match was not found.
Fixex RHBZ #638050.
Current solution uses same trick as mount and detects vg-lv name through
/sys where available - this should be reasonable safe.
Instead of calling mount without parameter to get actual mount table,
switch to use /proc/mounts directly.
Fix missing 'dry' execution of lvresize - fixing problem where resize
command were 'dry-run' executed - but lvresize has been executed for real.
Also adapt code slightly to support better recursive execution of fsadm
through lvresize call.
Under certain conditions it was possible to break (^C) fsadm before actually
resizing filesystem, but lvresize which executed fsadm will think resize
was succesful and shrinks partitions with unresized filesystem on it.
Fix by returning error (1) for this case - this stops lvresize from futher
proceding in resize operation.
In other LVM memory structures such as volume_group, the field
used to store flags is called "status", and on-disk fields are called
'flags', so rename the one inside metadata_area to be consistent.
Not only is it more consistent with existing code but is cleaner
to say "the status of this mda is ignored".
Background for this patch - prajnoha pinged me on IRC this morning
about a fix he was working on related to metadataignore when
metadata/dirs was set. I was reviewing my patches from this year
and realized the 'flags' field was probably not the best choice
when I originally did the metadataignore patches.
Current lvm1 allocation code seems to not properly
map segments on missing PVs.
For now disable this functionality.
(It never worked and previous commit just introduced segfault here.)
So the partial mode in lvm1 can only process missing PVs
with no LV segments only.
Also do not use random PV UUID for missing part but use fixed
string derived from VG UUID (to not confuse clvmd tests).
We need to use a similar function for pv and lv properties, so just make
a generic _get_property() function that contains most of the required
functionality. Also, add a check to ensure the field name matches the
object passed in by re-using report_type_t enum. For pv properties,
the report_type might be either PVS or LABEL.
In addition, add 'const' to 'get' functions object parameter, but not
'set' functions. Add _not_implemented_set() and _not_implemented_get()
functions.
Add 'get' functions based on generic macros for VG, PV, and LV.
Add 'get' functions for vg string fields, vg_name, vg_fmt, vg_sysid,
vg_uuid, vg_attr, and vg_tags, and all numeric fields.
Add supporting functions for vg_name, vg_fmt, vg_system_id.
Append "_dup" to end of supporting functions to make clear the strings
are dup'd and to avoid namespace conflict with vg_name.
Add supporting functions for pv_uuid, vg_uuid, and lv_uuid.
Call new function id_format_and_copy. Use 'const' where appropriate.
Add "_dup" suffix to indicate memory is being allocated.
Call {pv|vg|lv}_uuid_dup from lvm2app uuid functions.
This patch addresses code review request to simplify creation of 'attr'
strings. The simplification is done in this separate patch to more
easily review and ensure the simplification is done without error.
Move the creating of the 'attr' strings into a common function so
they can be called from the 'disp' functions as well as the new
'get' property functions.
Add "_dup" suffix to indicate memory is allocated.
Refactor pvstatus_disp to take pv argument and call pv_attr_dup().
This patch is similar to the other patches for pv and vg
functionality, and separates lv functionality into separate
files, concentrating on reporting fields and simple functions.
The metadata.[ch] files are very large. This patch makes a first
attempt at separating out pv functions and data, particularly
related to the reporting fields calculations.
More code could be moved here but for now I'm stopping at reporting
functions 'get' / 'set' functions.
The metadata.[ch] files are very large. This patch makes a first

Read complete content of /proc/self/maps into one buffer without
realocation in the middle of reading and before doing any m/unlock
operation with these lines - as some of them gets change.
With previous implementation we've read some mappings twice ([stack])
