please attach engine log as well. Jiri, I suspect something is wrong with the export path, can you please execute the following commands on the hypervisor: tree /rhev/data-center/ffec9aa4-692c-11e2-9e91-001a4a013f3a ls -l /rhev/data-center/ffec9aa4-692c-11e2-9e91-001a4a013f3a/131d564c-52d1-4bba-8d60-39e889a8bc08/images/62787b06-d836-4e14-afc7-023e08aeee96 Created attachment 715897 [details]

All engine logs
In the engine logs, failed attempts of attach the export were found. In addition, recurrent attempts to activate this export found too. They failed. Probably the fact that the sdUUID of the export is part of the pool, in spite the failed attaches is consequence of a wrong reconstruct master. Pool and domain metadata should be manually corrected in order to use this export. (In reply to comment #10) > Pool and domain metadata should be manually corrected in order to use this > export. Domain was probably force detached from the pool. This is a known design issue and will be taken care of once we get rid of the export domain entirely.

I don't think so, we need to understand how system got to a state where export domain metadata contains wrong pool, export domain status is up and active, hence export process starts and fails. moving back to assigned, scrubbing is needed from engine side.

Ack, I missed the part where it became up on engine. The comment #10 states true, POOL_UUID in export domain metadata was not my storage pool id. I don't know how exactly it has happened (comment #11 + comment #12) but truth is, this export domain is "shared" by our team. Right now I force detached the export domain as I could not remove it, manually removed id from POOL_UUID and _SHA_CKSUM and reimported the export domain again. I can import from the domain now. If you think this was caused by PEBKAC issue, feel free to close the BZ. closing for now (smells like manual intervention + modification of MD was in place). feel free to re-open if issue reproduces. |
