David Teigland	fd1782b5fc	lvmlockd: handle loss of sanlock lease storage ... This adds the infrastructure, code paths, error reporting, etc. to handle storage errors, or storage loss, under the sanlock leases in a VG that is being used. The loss of storage means sanlock cannot renew its leases, which means that the host needs to stop using the shared VG before its leases expire. This still requires manually shutting down a VG that has lost lease storage, e.g. unmounting file systems, deactivating LVs in the VG. The next step is to automatically use a command like blkdeactivate to do that.	2015-08-05 10:21:45 -05:00

David Teigland	9aabf441bd	vgremove: warn when removing sanlock global lock ... When the sanlock VG holding the global lock is removed, print a warning indicating that the global needs to be enabled in another sanlock VG.	2015-07-29 14:27:32 -05:00
David Teigland	268f53ed0d	lockd: fix error cases when built without lvmlockd ... When lvm is built without lvmlockd support, vgcreate using a shared lock type would succeed and create a local VG (the --shared option was effectively ignored). Make it fail. Fix the same issue when using vgchange to change a VG to a shared lock type. Make the error messages consistent.	2015-07-16 15:22:06 -05:00
