lvm2 warned about zeroing and too big chunksize (>=512KiB), but
only during lvconvert, so lvcreate was creating thin-pools
without any warning about possible slowness of thin provisioning
because of zeroing.
Create a new table output format that concisely shows multiple devices
on one line.
dmsetup table --concise [device...]
<dev_name>,<uuid>,<flags>[,<table>]*[;<dev_name>,<uuid>,<flags>[,<table>]*]*
Table lines are separated by commas.
Devices are separated by semi-colons.
Flags is currently 'ro' or 'rw' (and might be extended in a
yet-to-be-defined way in future).
Any comma, semi-colon or backslash within a field is quoted by a
preceding backslash.
The format can later be supplied as input to dmsetup or even to the
booting kernel as an alternative way to set up devices.
Based on patches submitted by
Enric Balletbo i Serra <enric.balletbo@collabora.com>.
Add an independent command definition for "vgchange --locktype",
and split the implementation out of the set of common metadata
changes. It is unlike normal metadata changes, and can only
be run by itself. (Changing the lock type is similar in
principle to changing the VG name or the VG system ID; it
effects the ability of any host to see or access the VG.)
At some point this command lost the ability to forcibly change
the lock type of a shared VG to "none" (making it a local VG).
This can be necessary to repair shared VGs (e.g. recovery steps
that occur in vg_read are disabled for shared VGs because
they are not locked properly, or recovering sanlock locks
when the PV holding them is lost.)
"vgchange --locktype none --lockopt force VG" is used as the
method of forcing the shared VG to become local so that it
can be repaired.
Commit 9b4b5d449e started to accept
rather way to wide set of strings we do not want to take for size.
i.e. lvresize -t vg0/lvol0 -LNaNM
Restore check for 'digit || locales defined 'dot' | '.'
(as we tend to take '.' even if locales uses ',')
Explictely detect duplicate sing symbols and leave the rest of
double number validation on 'strtod()' function. This way
we can also accept size like:
lvcreate -L.1M
We already accept -L0.1M - but it's common to accept numbers
starting with leading '.' - just as 'strtod()' accepts it).
API for strtod() or strtoul() needs reset of errno, before it's being
called. So add missing resets in missing places and some also some
errno validation for out-of-range numbers.
Since we are reading size as (double) we can get way bigger
number then just plain int64. So to make this check actually
more valid and usable do a maxsize compare in 'double'.
Fix the error messages when an unrecognized command is
run from a script. We shouldn't attempt to parse options
for an unrecognized command name, which causes misleading
errors about bad options, but rather exit right when we
know the command name is not valid. Also don't complain
about exiting without an error message when running a
script if no command didn't exist.
lvm_run needs to place NULL as the last element into argv[].
Otherwise we get:
Conditional jump or move depends on uninitialised value(s)
_command_required_pos_matches (lvmcmdline.c:1443)
_find_command (lvmcmdline.c:1610)
lvm_run_command (lvmcmdline.c:2770)
lvm2_run (lvmcmdlib.c:91)
When raid leg rimage device is marked as 'D'ead by mdcore,
lvm2 was not able to replace such device with allocate policy,
as device has not appared as missing.
Add detection of transiently failing devices.
When old snapshot is merged, lvm2 still can report some data about
merged 'snapshot' - i.e. it occupied space in VG.
This patch fixes regression from commit:
6fd20be629
and resolved RHBZ: 1460161
Code path missed validation of lvcreate --cachepool argument.
If the non cache-pool LV was passed in, code has still continued
further work and failed later on internal error. Validate this
condition at right place now.
Add an exception to not allowing lvchange to change properties
on hidden LVs. When a thin pool data LV is a cache LV, we
need to allow changing cache properties on the tdata sublv of
the thin pool.
Trap cases where the percentage calculation currently leads to an empty
LV and the message:
Internal error: Unable to create new logical volume with no extents
Additionally convert the calculated number of extents from physical to
logical when creating a mirror using a percentage that is based on
Physical Extents. Otherwise a command like 'lvcreate -m3 -l80%FREE'
can never leave any free space.
This brings the behaviour closer to that of lvresize.
(A further patch is needed to cover all the raid types.)
There were a handful of references to other man
pages using the standard command(N) form which were
not in bold, so they were not turned into links
in html formats.
