David Teigland	9cfa27f9c5	lockd: allow nolocking and readonly options ... When --nolocking is used (by vgs, lvs, pvs): . don't use lvmlockd at all (set use_lvmlockd to 0) . allow lockd VGs to be read When --readonly is used (by vgs, lvs, pvs, vgdisplay, lvdisplay, pvdisplay, lvmdiskscan, lvscan, pvscan, vgcfgbackup): . skip actual lvmlockd locking calls . allow lockd VGs to be read . check that only shared gl/vg locks are being requested (even though the actually locking is being skipped) . check that no LV locks are requested, because no LVs should be activated or used in readonly mode . disable using lvmetad so VGs are read from disk It is important to note the limited commands that accept the --nolocking and --readonly options, i.e. no commands that change/write a VG or change/activate LVs accept these options, only commands that read VGs.	2015-07-13 13:15:51 -05:00
David Teigland	0823511262	lockd: disable part of lock_args validation ... There are at least a couple instances where the lock_args check does not work correctly, (listed in the comment), so disable the NULL check for lock_args until those are resolved.	2015-07-10 15:53:21 -05:00

David Teigland	633aea92fb	config: remove read_only_lock_modes ... It had been added as part of lvmlockd code, but it does not seem particularly useful.	2015-07-06 11:44:28 -05:00
David Teigland	e1733a6271	lockd: remove unused code for overriding lock modes ... including the allow_override_lock_modes setting. It was not possible to override default lock modes any longer, since the command line options had already been removed. A mechanism will probably be required later that puts part of this back.	2015-07-06 11:44:28 -05:00
David Teigland	114744cee1	config: rename lock_retries lvmlockd_lock_retries ... Because it only applies to lvmlockd requests, but sounded too general.	2015-07-06 11:44:28 -05:00
