The backup() call store metadata from memory.
But in cluster backup() call performs
remote nodes metadata backup and it reads data from disk.
For metadata backup consistency,
patch moves all backup() calls after vg_commit.
(Moreover, some tools already do that this way.)
Using argv[] list in exec_cmd() to allow more params for external commands.
Fsadm does not allow checking mounted filesystem.
Fsadm no longer accepts 'any other key' as 'no' answer to y/n.
Fsadm improved handling of command line options.
BEFORE:
tools/lvm lvresize -l +4 vg22/lv1linear
Volume group "vg22" not found
Volume group vg22 doesn't exist
AFTER:
tools/lvm lvresize -l +4 vg22/lv1linear
Volume group "vg22" not found
Fix unfilled paramater passed to fsadm from lvresize
Update fsadm to call lvresize if the partition size differs (with option -l)
Fix fsadm to support vg/lv name (like the rest of lv-tools)
Fix missing VG unlocks in some pvchange error paths.
Add some missing validation of VG names.
Rename validate_vg_name() to validate_new_vg_name().
Change orphan lock to VG_ORPHANS.
Change format1 to use ORPHAN as orphan VG name.
e.g. lvcreate -l 100%FREE to create an LV using all available space.
lvextend -l 50%LV to increase an LV by 50% of its existing size.
lvcreate -l 20%VG to create an LV using 20% of the total VG size.
Add --config for overriding most config file settings from cmdline.
Quote arguments when printing command line.
Remove linefeed from 'initialising logging' message.
Add 'Completed' debug message.
Don't attempt library exit after reloading config files.
Always compile with libdevmapper, even if device-mapper is disabled.
Fix some memory leaks in error paths found by coverity.
Use C99 struct initialisers.
Move DEFS into configure.h.
Clean-ups to remove miscellaneous compiler warnings.
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-) (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug
to back this out so you can do that commit, let me know. Also, if there's
an issue with the error message that's displayed, just change it in tools.h.
This causes a "device-mapper driver/module not loaded?" error message to
be displayed for the commands that require dm-mod, if the tools can't get
the driver version. It's not done for commands that don't require dm-mod.
This should clear up some problems people have had attempting to use lvm2
without rtfm'ing.
Lots of changes/very little testing so far => there'll be bugs!
Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files. Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.
Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).
e.g. metadata {
dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}
Plenty of refinements still in the pipeline.
from lock_vol() - otherwise it now attempts to acquire the lock and then
immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible. (Another
step towards using them instead of VG names internally.)
o #defines for common lock flag combinations
o Try out hyphens instead of colons in device-mapper names - does this
make messages containing filenames easier to read?
and add severe warning if it's used to make a device seem bigger than
it really is. This is not an option people should be using as it
breaks metadata integrity.
o Use uint64_t throughout (rather than unsigned long long)
o Convert a few messages that contain pathnames into the more common form:
pathname: message
struct pv_list {
struct list list;
struct physical_volume pv;
};
to
struct pv_list {
struct list list;
struct physical_volume *pv;
};
o New function in toollib 'create_pv_list', which creates a list of pv's
from a given command line array of pv's.
o Changed lvcreate/extend to use this (fixes lvextend [pv list] bug).
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.
