hi,
first try to deport and import see if that fixes your problem. If not, then check file system /var if it is filled up.
If so, file /var/vxvm/tempdb/<dbname> might get corrupted.
clean up /var file system, then after make sure no any DGs are imported, fire the below command
vxdctl stop
vxconfigd -x cleartempdir
Pls kindly update us with your outcome.
