On http://docs.linbit.com/doc/users-guide-84/s-resizing/ states that an online re-size requires your backing devices are on a 'logical volume management subsystem, such as LVM'. The 8.3 manual contains similar, and 9.0 may as well I believe this is in error, because mdadm, iscsi, and SAS RAID backing devices would work just fine if they can be grown online as well and there's no partitions (like msdos or gpt) in the way. I propose replacing: 1) The affected resource’s backing device must be one managed by a logical volume management subsystem, such as LVM. 2) The resource must currently be in the Connected connection state. with: 1) The affected resource’s backing devices must themselves be able to be gown online, such as LVM LV, mdadm raid device, iSCSI lun, DAS Raid or others. 2) The affected resource’s backing devices must NOT be an MSDos or GPT partition as partitions can not be resized online. 3) The resource must currently be in the Connected connection state. Also, I believe I was able to successfully resize a resource with both sides primary, which the documentation advises against. Did drbdadm let me put my resource at risk, or is there some reasoning that should accompany the manual's advice against it? -------------- next part -------------- An HTML attachment was scrubbed...
