When chunk size needs to be estimated, the code missed to round
to proper 64kb boundaries (or power of 2 for older thin pool driver).
So for some data and metadata size (i.e. 10GB and 4MB) it resulted
in incorrect chunk size (not being a multiple of 64KB)
Fix it by adding proper rounding and also use 1 routine for 2 places
where the same calculation is made.
Fix also incorrect printed warning that has used 'ffs()'
(which returns first 'least significant' bit in word)
and it was not really giving any useful size info and replace it
with properly estimated chunk size.
Fix regression introduced with a2c1024f6a
_setup_task(mknodes ? name : NULL...
has been replaced with:
_setup_task(type != MKNODES ? name : NULL....
Use '=='
Commit d2c116058e introduced regression
with CLVMD_PATH.
+ CLVMD_PATH="$clvmd_prefix/sbin/clvmd"
test "$prefix" != NONE && clvmd_prefix=$prefix
It has set CLVMD_PATH before clvmd_prefix got its final value.
Move it one line below.
systemd-run is available in systemd>=205. Also, this fix prevents
systemd-specific udev rules in 69-dm-lvm-metad.rules to appear in
case systemd environment is not available - make configure to check
this automatically and use these systemd specific rules only if it
is applicable.
Rework ignore_vg() API so it properly handles
multiple kind of vg_read_error() states.
Skip processing only otherwise valid VG.
Always return ECMD_FAILED when break is detected.
Check sigint_caught() in front of dm iterator loop.
Add stack for _process failing ret codes.
Failed recovery provides different (NULL) VG then FAILED_INCONSISTENT.
Mark it with different failure bit - since FAILED_INCONSISTENT is
supposed to contain something 'usable' (thought inconsistent).
More efficient spare volume creation. Save 1 extra commit
and properly activate this volume according to our cluster
activation rules (using lv_active_change() for this).
Since we 'layer' for cache origin which and we support dropping
cache layer - we need to restore origin name in case
the origin LV is more complex target - i.e. raid.
Drop _corig from name
Cleanup and rename parent -> parent_lv.
When deactivating origin, we may have possibly left table in broken state,
where origin is not active, but snapshot volume is still present.
Let's ensure deactivation of origin detects also all associated
snapshots are inactive - otherwise do not skip deactivation.
(so i.e. 'vgchange -an' would detect errors)
When responding to DM_EVENT_CMD_GET_REGISTERED_DEVICE no longer
ignore threads that have already been unregistered but which
are still present.
This means the caller can unregister a device and poll dmeventd
to ensure the monitoring thread has gone away before removing
the device. If a device was registered and unregistered in quick
succession and then removed, WAITEVENT could run in parallel with
the REMOVE.
Threads are moved to the _thread_registry_unused list when they
are unregistered.
Call check_new_thin_pool() to detect in-use thin-pool.
Save extra reactivation of thin-pool when thin pool is not active.
(it's now a bit more expensive to invoke thin_check for new pools.)
For new pools:
We now active locally exclusively thin-pool as 'public' LV.
Validate transaction_id is till 0.
Deactive.
Prepare create message for thin-pool and exclusively active pool.
Active new thin LV.
And deactivate thin pool if it used to be inactive.
Show some stats with 'lvs'
Display same info for active cache volume and cache-pool.
data% - #used cache blocks/#total cache blocks
meta% - #used metadata blocks/#total metadata blocks
copy% - #dirty/#used cache blocks
TODO: maybe there is a better mapping
- should be seen as first-try-and-see.
New size_mb_arg_with_percent is able to read size_mb_arg
but also it's able to read % values.
Percent parsing is share with int_arg_with_sign_and_percent.
If root has locales with different decimal point then '.'
(i.e. Czech with ',') lets be tolerant and retry with
"C" locales in the case '.' is found during parse of number.
Locales are then restored back.
Support compile type configurable defaults for creation
of sparse volumes.
By default now create 'thin-pools' for sparse volumes.
Use the global/sparse_segtype_default to switch back to old
snapshots if needed.
Apply the same compile logic for newly introduces mirror/raid1 options.
Use segment flags to avoid zeroing of cache, cache pool
snapshot and thin pool segments.
We never want to zero these segment types.
Note:
Snapshot COW and Cache origin are created as stripes
thus are then properly zeroed.
Let the finaly state of zero & wipe_signature to be
resolved later together with all the types.
Don't play with zero assigment and segtype flag
(i.e. thin-pool -Z has different meaning).
Check if the passed options do allow requested zeroing/wiping.
lvcreate without -Z or -W will fallback to warning if the device
cannot be zeroed, however if user requested them explicitely
it will give user error.
Refactor lvcreate code.
Prefer to use arg_outside_list_is_set() so we get automatic 'white-list'
validation of supported options with different segment types.
Drop used lp->cache, lp->cache and use seg_is_cache(), seg_is_thin()
Draw clear border where is the last moment we could change create
segment type.
When segment type is given with --type - do not allow it to be changed
later.
Put together tests related to individual segment types.
Finish cache conversion at proper part of lv_manip code after
the vg_metadata are written - so we could correcly clean-up created
stripe LV for cache volume.
We want to print smarter warning message only when
the zeroing was not provided on the first zeroable segment
of newly created LV.
Put warning within _should_wipe_lv function to avoid reevaluation
of same conditions twice.
Hide creation of temporary LVs and print them only in verbose mode.
e.g. hides confusing message about creation of _pmspare
device during creation of pool.
Ask for lock the proper LV.
Use the top-most LV to query for locally exclusive lock.
The rest of operations are then using 'lv_info()'
TODO:
Check all devices are reloaded from proper level.
In general any query on lv_is_active is supposed to be running
ona lv_lock_holder() volume.
Instead of segtype->ops->name() introduce lvseg_name().
This also allows us to leave name() function 'empty' for default
return of segtype->name.
TODO: add functions for rest of ops->
There was a bug in value and their synonym definition for these two fields
causing selections on these fields to not work correctly - nothing matched
against vg/lv_permissions fields even if selection criteria should have
matched.
Scenario:
$ lvs -o name,lv_permissions vg
LV LPerms
lvol0 read-only
lvol1 writeable
Before this patch:
$ lvs -o name,lv_permissions vg -S 'permissions=read-only'
(blank)
$ lvs -o name,lv_permissions vg -S 'permissions=writeable
(blank)
With this patch applied:
$ lvs -o name,lv_permissions vg -S 'permissions=read-only'
LV LPerms
lvol0 read-only
$ lvs -o name,lv_permissions vg -S 'permissions=writeable'
LV LPerms
lvol1 writeable
Also synonyms match correctly now:
$ lvs -o name,lv_permissions vg -S 'permissions=rw'
LV LPerms
lvol1 writeable
Fix lvm_split that is called when cmd line string is separated into
argv fields to recognize quote chars ('\'" and '"') properly and
when these quotes are used, consider the text within quotes as one
argument, do not separate it based on space characters inside.
The lvm_split is used during processing lvm shell command line or
when calling lvm commands through cmdlib (e.g. dmeventd plugins).
For example, the lvm shell scenario:
Before this patch:
$lvm
lvm> lvs --config 'global{ suffix=0 }'
Parse error at byte 9 (line 1): unexpected token
Failed to set overridden configuration entries.
With this patch applied:
$lvm
lvm> lvs --config 'global{ suffix=0 }'

(Exactly the same problem is hit when calling LVM commands with
quoted arguments via lvm2cmd lib in dmeventd plugins.)
