This bug has been copied from bug #676582 and has been proposed to be backported to 5.6 z-stream (EUS).
Checked on vdsm22-4.5-63.22.
Woops. Still reproduces on 4.5-63.22.
Actually, what you saw is our mishandling of missing POOL_DESCRIPTION (bug 684725). This bug is about our erasing of this field (the title is confusing...) To avoid confusion, I'll ask to reverify the issue only on a build with both bugs resolved.
Verification Description (Verified vdsm22-4.5-63.24.el5_6,Using RHEVM 2.2-GA): ******************************************************************************* 1) Create on host (with old version of vdsm_2.2.5 NFS data storage domain and attach it to NFS Data-Center. 2) After host 'contending' and become SPM--> on storage machine edit the NFS data storage-domain meta-data: 'vi /<storge_domain_uuid>/dom_md/metadata' A) remove the 'POOL_DESCRIPTION' line. B) remove the '_SHA_CKSUM=c' line. 3) maintenance the host. 4) upgrade vdsm22 rpm's on the host (to version 2.2.7). 5)activate the host and verified that host 'contending' and connectStoragePool Succeeded. Note: ***** verified the above test for switch between builds: - 2.2.5 to 2.2.6 to 2.2.6.1 to 2.2.7. - 2.2.5 directly to 2.2.7. - 2.2.6 directly to 2.2.7.
