VG uuids can be used in place of VG names as command
args for commands using process_each_vg. The command
line uuid format includes dashes.
As with tags, processing vg uuid args requires
process_each_vg to read all vgs to match their
uuid against the uuid args.
If a command line uuid arg matches one vg's name
and another vg's uuid, the vg with matching name
will be selected.

Process pvs by iterating through vgs, then iterating through
devs if the command wants to process non-pv devices. The
process_single function can always use the vg and pv args.
|
| |
|
|
|
|
|
| |
The ENABLE_ALL_DEVS flag is added to the command structure
for commands that should process all devs (pvs and non-pvs)
when they call process_each_pv and the command includes the
--all arg. This will be used in a later process_each_pv patch.
|

|
|
|
| |
The failed_lvnames arg is no longer used since the
cmd_vg replicator wrapper was removed.
|
| |
|
|
| |
Include in the error message the lv name args that were not found.
|
| |
|
|
|
|
| |
- Copy the same form as the new process_each_vg.
- Replace unused struct cmd_vg and cmd_vg_read() replicator
code with struct vg and vg_read() directly.
|
| |
|
|
|
|
|
|
| |
- Split the collecting of arguments from processing them.
- The split allows the two different loops through vgs to
be replaced by a single loop.
- Replace unused struct cmd_vg and cmd_vg_read() replicator
code with struct vg and vg_read() directly.

The ENABLE_ALL_VGS flag is added to the command structure
for commands that should process all vgs when they call
process_each_vg or process_each_lv with no args.
This will be used in later patches to process_each functions.

kernels > 2.4
Since kernel > 2.4 have dynamically assigned major numbers.
[0] raw/~ $ lvcreate -l1 -My --minor 10 vg
Logical volume "lvol0" created
[0] raw/~ $ lvcreate -l1 -My --major 254 --minor 11 vg
Ignoring supplied major number - kernel assigns major numbers dynamically. Using major number 253 instead.
Logical volume "lvol1" created
[0] raw/~ $ lvs --profile out -o+major,minor
lvol0 vg -wima----- 4.00 253 10
lvol1 vg -wima----- 4.00 253 11

Update thin provisioning tools to version 0.3.2 or later!

Avoid using variables with same name as functions.
Use lvm_even_rand for random numbers.

When down-converting a RAID1 LV, if the user specifies too few devices,
they will get a confusing message.
Ex:
[root]# lvcreate -m 2 --type raid1 -n raid -L 500M taft
Logical volume "raid" created
[root]# lvconvert -m 0 taft/raid /dev/sdd1
Unable to extract enough images to satisfy request
Failed to extract images from taft/raid
This patch makes the error message a bit clearer by telling the user
the count they are trying to remove and the number of devices they
supplied.
[root@bp-01 lvm2]# lvcreate --type raid1 -m 3 -L 200M -n lv vg
Logical volume "lv" created
[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sdb1
Unable to remove 3 images: Only 1 device given.
Failed to extract images from vg/lv
[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bc]1
Unable to remove 3 images: Only 2 devices given.
Failed to extract images from vg/lv
[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bcd]1
[root@bp-01 lvm2]# lvs -a -o name,attr,devices vg
LV Attr Devices
lv -wi-a----- /dev/sde1(1)
This patch doesn't work in all cases. The user can specify the right
number of devices, but not a sufficient amount of devices from the LV.
This will produce the old error message:
[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bcf]1
Unable to extract enough images to satisfy request
Failed to extract images from vg/lv
However, I think this error message is sufficient for this case.

Initial description and instructions for
data/metadata space exhaustion.

For cache flushing local exlusive activation is needed.

TODO: in fact we should parameter LV.
|

|

|

Passing non cached device is an internal error.
Print messages at non-error level.
Shorten sleep delay for cache flush.
|
| |
|
|
| |
Policy should be const char pointer.
|
| |
|
|
| |
Using same error message for pool associated devices.
|
| |
|
|
|
|
| |
Start to change metadata after they are archived.
And since cache_pool is virtual skip deactivation
call for this LV.
|
| |
|
|
|
|
|

Since the usability problem were fixed, we can use this function.
Cleanup orphan LVs with TEMPORARY flags
(reduces couple blkid error reports, but couple of them
is still left...)

Since cache segment is purely virtual mapping, it has nothing for
discard. Discardable is cache origin here which is now
properly removed on 'delete' phase.
Plain lv_empty() call needs to only detach cache origin and leave
origin unchanged.
|
| |
|
|
|
| |
Since cache-pool is purely lvm abstraction layer LV, it never
need any device node, so do not add even 'error' device for it.

config/config_settings.h:257:102: error: 'DMEVENTD_PATH' undeclared here (not in a function)

Drop test, which are now in other files (listings.sh)
|

|

|
|

Use normal '||'.
|

|

Since the whole dm device name may not exceed 127 characters,
validate no LV names is bigger then this limit.
|

Failing resume path means command has failed,
even when commit was ok.
