When cmd refresh is called, we need to move any already loaded profiles
to profiles_to_load list which will cause their reload on subsequent
use. In addition to that, we need to take into account any change
in config/profile configuration setting on cmd context refresh
since this setting could be overriden with --config.
Also, when running commands in the shell, we need to remove the
global profile used from the configuration cascade so the profile
is not incorrectly reused next time when the --profile option is
not specified anymore for the next command in the shell.
This bug only affected profile specified by --profile cmd line
arg, not profiles referenced from LVM metadata.
Before, the cft_check_handle used to direct configuration checking
was part of cmd_context. It's better to attach this as part of the
exact config tree against which the check is done. This patch moves
the cft_check_handle out of cmd_context and it attaches it to the
config tree directly as dm_config_tree->custom->config_source->check_handle.
This change makes it easier to track the config tree check results
and provides less space for bugs as the results are directly attached
to the tree and we don't need to be cautious whether the global value
is correct or not (and whether it needs reinitialization) as it was
in the case when the cft_check_handle was part of cmd_context.
Share DM_REPORT_FIELD_RESERVED_NAME_{HELP,HELP_ALT} between libdm and
any libdm user to handle reserved field names, in this case the virtual
field name to show help instead of failing on unrecognized field.
The libdm user also needs to check the field name so it can fire
proper code in this case (cleanup, exit etc.).
When showing ACTIVE status for snapshot's origin,
avoid testing all its snapshot - it's not useful
to tell user origin is inactivate, while it's clearly
available and running - just one of its snapshot leg
is invalid...
While the 'raid1/10' segment types were being handled inadvertently
by '_move_mirrors()', the parity RAIDs were not being properly checked
to ensure that the user had specified all necessary PVs when moving
them. Thus, internal errors were being triggered when only part of
a RAID LV was moved to the new VG. I've added a new function,
'_move_raid()', which properly checks over any affected RAID LVs and
ensures that all the necessary PVs are being moved.
Config variables that are processed during setup prior to calling into
particular tools must not be accessed directly afterwards in case the
values already got overridden.
_process_config() already used the tests I'm removing here to call
lvmetad_set_active() and set up lvmetad_used().
There were two bugs before when using pvcreate --restorefile together
with data alignment and its offset specified:
- the --dataalignment was always ignored due to missing braces in the
code when validating the divisibility of supplied --dataalignment
argument with pe_start which we're just restoring:
if (pp->rp.pe_start % pp->data_alignment)
log_warn("WARNING: Ignoring data alignment %" PRIu64
" incompatible with --restorefile value (%"
PRIu64").", pp->data_alignment, pp->rp.pe_start);
pp->data_alignment = 0
The pp->data_alignment should be zeroed only if the pe_start is not
divisible with data_alignment.
- the check for compatibility of restored pe_start was incorrect too
since it did not properly count with the dataalignmentoffset that
could be supplied together with dataalignment
The proper formula is:
X * dataalignment + dataalignmentoffset == pe_start
So it should be:
if ((pp->rp.pe_start % pp->data_alignment) != pp->data_alignment_offset) {
...ignore supplied dataalignment and dataalignment offset...
}
This test for LV name restriction check name of device is below 128
chars (which is enforced by dm target).
Thus it should not count with device name.
(Though the test for PATH_MAX size should be probably also added,
but this is runtime test, since theoretically devpath might differ in cluster)
It's unclear why we should prohibit use of -v output.
So reenable (like with other 'display' tools)
But -c -m is really unsupported - return invalid cmd.
Commit 1a832398a7caa96faab2ccbac773cc4047c8f9c1 moved
some code from _pvchange_single() to main pvchange() and
introduced exit code regression as return codes have not
been properly changed, thus pvchange command exited
with '0' exit code, even though it has reported error.
Also there is a missing vg unlock in error path.
Fix it by counting the total number of expected calls before
checking for pvname and also unlock and relase vg when
pv is not found.
Since commit f12ee43f2eaba5d38b1925a5a34b1746c1d66985 call destroy,
it start to check all VGs are unlocked. However when we become_daemon,
we simply reset locking (since lock is still kept by parent process).
So implement a simple 'reset' flag.
pvscan --uuid was broken since it was using only 128 char buffers
without checking any write size, so any longer device path leads to
crash.
Also ansure format is properly aligned into columns with this option.
Check whether lvm dumpconfig --mergedconfig is used only
with --type current (where we're merging current config and
the config supplied on command line). With other types
the config was merged, but it was thrown away since we're
generating other type of config anyway. This lead to a memleak.
Error out if --mergedconfig is used with anything else than
--type current (or without specifying --type in which case
the --type current is used by default).
