Unable to re-mirror volume after it cracked
We have primary NAS <source> with volume <volume name> and this was mirrored to NAS <target>.
After the mirror broke or "cracked" . The mirror was deleted and then a re-mirror was attempted via GUI but this failed with the following status:
'Unable to attach parts'.
Error seen in the syslogs:
Also if you deleted the mirror set on the <source> and deleted the mirror volume on <target> and then tried to re-mirror the same error occured.
Note that the following message in the system events log 'nbd: Could not locate nbd connected disk for dasd id xxxx.
Other symptoms : On the <source> the volume is composed of two partitions of xxxMB and xxxMB. Before deleting the mirror volume on the <target> NAS it was identical to the <source> NAS i.e. two partitions.
Now you can see only one xxxxMB partition <target>. The other partition that was part of the volume shows as being 'free to allocate'.
