Re: [libvirt] [PATCH v2] storage: Adjust expected format for Disk startup processing

https://bugzilla.redhat.com/show_bug.cgi?id=1464313 If a Disk pool was defined/created using XML that either didn't specify a specific format or specified format type='unknown', then restarting a pool after an initial disk backend build with overwrite would fail after a libvirtd restart for a non-autostarted pool. This is because the persistent pool data is not updated during pool build w/ overwrite processing to have the VIR_STORAGE_POOL_DISK_DOS default format. So in addition to the alteration done during disk build processing, alter the default expectation for disk startup to be DOS if nothing has been defined yet. That will either succeed if the pool had been successfully built previously using the default DOS format or fail with a message indicating the format is something else that does not match the expect format 'dos'.

Rather than updating the persistent config file, alter the start processing to handle the unknown setting in the persistent file properly. src/storage/storage_backend_disk.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
