Heading back to my former question, Is it advisable to split huge storage into smaller chunks? Instead of: [ ------------- big LV ------------ ] [ ------------- big VG ------------ ] [ -> expand later ] [ ---------- big DRBD PV ---------- ] / \ Tgt1 Tgt2 maybe [ ------------- big LV ------------ ] [ ------------- big VG ------------ ] [ DRBD PV1 ][ DRBD PV2 ] [ DRBD PV3 ] / \ / \ / \ Tgt1a Tgt2a 1b 2b 1c 2c ... just wondering if syncing would scale better this way ... > -----Original Message----- > From: drbd-user-bounces at lists.linbit.com [mailto:drbd-user- > bounces at lists.linbit.com] On Behalf Of netz-haut - stephan seitz > Sent: Wednesday, February 23, 2011 9:00 AM > To: drbd-user at lists.linbit.com > Subject: [DRBD-user] possibility of "pre-sync" ? > > Hi there, > > I'm going to expand two storages by each 16TB.
