32c84c8f3d Add skeleton for lvmetad udev rules - 69-dm-lvm-metad.rules.
Why using the order 69:

  - Storage processing in general happens in 60-persistent-storage.rules,
    including the blkid call that adds some usable information we can use
    for filtering and speedup (these rules are part of upstream udev and
    the order is preserved on most distros)

  - There's still some other storage-related processing done after
    60-persistent-storage.rules in general. These might add some detailed
    storage-related information we might use to filter devices effectively
    (e.g. MD udev rules, ...).

  - We need lvmetad rules to be processed before any consumers can use the
    output - so the metadata cache is ready soon enough (e.g. udisks rules).

  - There's no official (upstream udev) document about assigning the order,
    so this number is chosen in best belief it will suit all scenarios.

b3d10d7bf1 Introduce dm_strncpy
Should be faster then strncpy - since we could avoid clearing 4KB pages
with each strncpy(...,PATH_MAX).
Also it's easy to check whether string fit - and eventually avoid
to continue working we incomplete string.

f72b184e3e Limit number of mem allocs and copies
If we have good enough glibc to return number of needed chars, do not
loop try to reach good size, but use this size directly for allocation,
saving also last strdup.

Since now we start with 16 bytes - skip buffer realloc for shorter string.

otherwise.

d4836062ff Add a vgscan to lvcreate-repair.sh. The old test applied device filter hacks to
make devices invisible to lvm, but the behaviour of those is slightly different
than of actual missing devices. Running vgscan after re-enabling the device
triggers a metadata repair which is not done by vgremove -ff. This is not a
regression, merely an odd behaviour that has been around even before lvmetad.

f84d6048cf Use 'd' instead of 'D' in tmpfiles configuration to not overwrite any existing directory.
...that happens when systemd creates it first (e.g. based on a .socket unit)
before the tmpfiles.d content is executed.

9bdfb30720 Fix allocation code to allow replacement of single RAID 4/5/6 device.
The code fail to account for the case where we just need a single device
in a RAID 4/5/6 array.  There is no good way to tell the allocation functions
that we don't need parity devices when we are allocating just a single device.
So, I've used a bit of a hack.  If we are allocating an area_count that is <=
the parity count, then we can assume we are simply allocating a replacement
device (i.e. no need to include parity devices in the calculations).  This
should make sense in most cases.  If we need to allocate replacement devices
due to failure (or moving), we will never allocate more than the parity count;
or we would cause the array to become unusable.  If we are creating a new device,
we should always create more stripes than parity devices.

0da6c851bd Add lvm2 tmpfiles.d configuration file. 2012-02-22 18:02:31 +00:00
Peter Rajnoha
4417a8bd40 Add configure --with-tmpfilesdir and lvm2 tmpfiles.d configuration file itself.
/etc/tmpfiles.d directory holds configuration files for temporary/volatile
files and directories that should be automatically managed. For example,
if we have some parts of the fs hierarchy on tmpfs, we'd like to recreate
some files or directories on every boot so they're always prepared for use.

Systemd can read such configuration files. For now, the lock and run directory
are the ones that are most probably placed on tmpfs. If this is the case, we
can install the configuration by 'make install_tmpfiles_configuration'.

7a5a5cb06f Add some messages that indicate completion of RAID device replacement.
There were no messages printed upon completiion of RAID device replacement.
This could cause confusion/concern during automated recovery, because the
user sees the failure messages but no other messages indicating correction.
