7e3d403b88 Implement a no_locking module that *does* attempt activation. 2002-04-11 14:10:32 +00:00

584404f8f4 Return status from _lv_activate and friends. 
Alasdair, I think this is right (and I need it) but you may like to check.

Joe Thornber
f31c47ade8 o Perform a BLKFLSBUF ioctl whenever a block device is closed. 
Patrick, can you see if this fixes your cluster syncing problem please ?
If so I'll make it so it only syncs if you have actually written to the
device.

ab053ad6c1 Fix lv_setup() not to generate a new lvid each time if asked to setup the 
same LV more than once - subsequent times validate only.

ae70673752 Make lock type numbers match the DLM numbers in use, and move UNLOCK out 
of the way.

7bb6856a7e Cope with creation of additional snapshots while active. 
(More work on suspension dependencies still needed.)
 2002-03-27 18:17:43 +00:00

4bb3eccf2b New-style persistent minor support. 2002-03-26 13:41:37 +00:00
Alasdair Kergon
e04c519896 o read-only device support 
o name/uuid disambiguation

a76ba817a8 Tie all snapshot (de)activation requests to (de)activation of origin device. 2002-03-18 13:09:27 +00:00

20ce742691 s/Removing/Unloading/ in messages to reduce confusion 2002-03-15 23:01:59 +00:00

a69de4919b Cut the number of device-mapper calls. 2002-03-15 22:59:12 +00:00
Alasdair Kergon
a6bf4bcfa2 New function to enable suppression of messages to stdout/stderr. 2002-03-15 22:54:04 +00:00
Alasdair Kergon
568d7229bf Review locking: block signals instead of ignoring them and restore state 
afterwards; avoid race condition with unlink; add LCK_HOLD to process_each_vg.
 2002-03-15 16:07:38 +00:00
Alasdair Kergon
14a9cda63b Reduce the number of dm info calls. 2002-03-14 21:17:30 +00:00

d8e7d77316 o dev_manager_suspend, untested. 2002-03-14 10:56:09 +00:00
Alasdair Kergon
dd420615d5 Set LV uuid. 2002-03-13 15:11:29 +00:00
Alasdair Kergon
251502f9a1 Move is_empty_dir to lvm-file 2002-03-11 22:23:24 +00:00
Joe Thornber
bb13858120 o Actually check that the vg directory is empty rather than speculatively 
rmdiring it.  Work around for devfs bug.
 2002-03-11 20:43:58 +00:00
Joe Thornber
2ec94d4daf o This should complete the dev_manager alg. Please could people now 
report any activation oddities they see.
 2002-03-11 20:36:04 +00:00
Alasdair Kergon
41967a0276 lv_info replaces lv_active etc. 2002-03-11 19:02:28 +00:00
Alasdair Kergon
be326a2f1b o activate/reactivate merge 
o unlocking macro
 2002-03-11 15:08:39 +00:00
Joe Thornber
323a167b49 o dm->active_list now filled in, ATM this is based on the layer name rather 
than the uuid.
 2002-03-11 11:27:48 +00:00
Joe Thornber
fd6932b18b o Comment out some new code that was preventing pjc activating 
snapshots.  This will go back in when the active_list is working.
 2002-03-11 10:38:16 +00:00
Joe Thornber
5295f36cb4 o knock out the offset for origin targets. 2002-03-08 10:45:01 +00:00
Joe Thornber
4526747997 o Add active_list to dev_manager 
o  Origin layer is only added to snapshots if a snapshot is in the
   active_list.
 2002-03-08 10:41:48 +00:00
Joe Thornber
11d2da4036 o First cut at dev scanning. 
o  Split up _expand_lv
 2002-03-07 17:37:38 +00:00
Joe Thornber
0fe3a2c512 o Add comment describing what we're aiming for with dev_manager. 
o  Remove dev_manager_reactivate, since it'll be the same as activate.

o  Merge the mark, visible and dirty fields into the same flags field.
 2002-03-07 16:48:46 +00:00
Joe Thornber
eea1d6932c o Top level device is now just called <vg>-<lv> (there's no 'top' 
layer appended).

o  Got rid of the unused layer->type field and enum.
 2002-03-07 15:29:31 +00:00
Alasdair Kergon
15c325f06a o Use new LCK_HOLD flag to indicate whether lock should be held on return 
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.)
 2002-03-05 20:03:09 +00:00
Alasdair Kergon
2731508b34 Fix activation for VG with more than one LV. 2002-03-04 18:50:34 +00:00
Joe Thornber
fdec53fb9c o Add a line to lvdisplay to say if the volume is a snapshot. 2002-03-04 15:12:30 +00:00
Joe Thornber
d30321a6cf o Bad dependency, meant the origin was always getting activated. 2002-03-04 15:10:30 +00:00
Alasdair Kergon
3bf898526a Remove unused fns. 2002-03-04 14:27:25 +00:00
Joe Thornber
3a84c18bdd o I was tearing down device bottom-up instead of top down. Which 
is why lvremove of snapshots wasn't working.
 2002-03-04 14:26:43 +00:00
Joe Thornber
9db196e6c5 o Break creating a snapshot down into: 
i)   create cow
   ii)  activate cow
   iii) zero cow
   iv)  deactivate
   v)   add snapshot info
   vi)  reactivate
 2002-03-04 13:46:37 +00:00

8c013da41f More use of LV locking. 2002-03-01 19:08:11 +00:00
Joe Thornber
6ed0234393 o point snapshots at origin:real rather than origin:top, and *ping* 
snapshots work.
 2002-03-01 09:07:00 +00:00
Alasdair Kergon
f4cbeaf0ac o Lock mechanism for LV activation 
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?
 2002-02-27 12:26:41 +00:00
Joe Thornber
841da63e77 o Format1 wasn't recording the snapshot chunk size properly 
o  Activation of snapshots now works - though the resulting device
   doesn't (pjc ?)

o  text format wasn't setting vg->cmd.
