There are a number of errors in the "ha_san_raid_lvm_aoe.pdf" document: *) Never put meta data on a loop device. It might deadlock under memory pressure. *) No need to create the file system on top of DRBD twice. Once on each node!! *) I got the impression you advise to mount an ext3 fs on the secondary (ro). This has a severe cache coherency issue, and should not be advised to anyone. The kernel patch simply drops all caches on the initiator side, which is rude in a way. Sorry, but I do not want to have this on .drbd.org as it is. -Phil -- : Dipl-Ing Philipp Reisner : LINBIT | Your Way to High Availability : Tel: +43-1-8178292-50, Fax: +43-1-8178292-82 : http://www.linbit.com DRBD(R) and LINBIT(R) are registered trademarks of LINBIT, Austria.
