Jonathan Brassow be75076dfc activation: Add "degraded" activation mode ... Currently, we have two modes of activation, an unnamed nominal mode (which I will refer to as "complete") and "partial" mode. The "complete" mode requires that a volume group be 'complete' - that is, no missing PVs. If there are any missing PVs, no affected LVs are allowed to activate - even RAID LVs which might be able to tolerate a failure. The "partial" mode allows anything to be activated (or at least attempted). If a non-redundant LV is missing a portion of its addressable space due to a device failure, it will be replaced with an error target. RAID LVs will either activate or fail to activate depending on how badly their redundancy is compromised. This patch adds a third option, "degraded" mode. This mode can be selected via the '--activationmode {complete|degraded|partial}' option to lvchange/vgchange. It can also be set in lvm.conf. The "degraded" activation mode allows RAID LVs with a sufficient level of redundancy to activate (e.g. a RAID5 LV with one device failure, a RAID6 with two device failures, or RAID1 with n-1 failures). RAID LVs with too many device failures are not allowed to activate - nor are any non-redundant LVs that may have been affected. This patch also makes the "degraded" mode the default activation mode. The degraded activation mode does not yet work in a cluster. A new cluster lock flag (LCK_DEGRADED_MODE) will need to be created to make that work. Currently, there is limited space for this extra flag and I am looking for possible solutions. One possible solution is to usurp LCK_CONVERT, as it is not used. When the locking_type is 3, the degraded mode flag simply gets dropped and the old ("complete") behavior is exhibited.		2014-07-09 22:56:11 -05:00
