Re: [lvm-devel] [PATCH - v2] LVM: New flag, LV_REBUILD



Dne 14.11.2011 19:06, Jonathan Brassow napsal(a):
Changes from previous:
- New rebuild flag is now written to on-disk LVM metadata
- An additional metadata write/commit is necessary to clear the flag
after a proper resume
- flags.c file updated

  brassow

Add new flag, LV_REBUILD.

Until now, I had been using the LV_NOTSYNCED as a flag to indicate that RAID
sub-LVs needed to be rebuilt.  (The 'rebuild' parameter is then specified in
the DM CTR table.)  However, I don't want to use a flag that gets written to
the LVM metadata... and the LV_NOTSYNCED flag's original meaning does not
suite the purpose adequately.

This patch proposes and uses a new flag, LV_REBUILD.

Hmm so now - when it's written to disk - it looks like LV_REBUILD and LV_NOTSYNCED is mostly the same meaning - except one is used in raid
and original in mirror ?

So I think it's easier to keep just one flag ?
(Well the bit field space is somewhat limited)
