This problem was fixed in snv_48 last September and will be in S10_U4. U4 doesn't help us any. We need the fix now. :-( By the time U4 is out, we may even be finished (certainly well on our way) our RAC/ASM migration and this whole issue will be moot. Rainer This message posted from

The limit is documented as 1 million inodes per TB. So something ust not have gone right. But many people have complained and you could take the newfs source and fix the limitation. Patching the source ourselves would not fly very far, but thanks for the clarification. I guess I have to

Yes, Anantha is correct that is the bug id, which could be responsible for more disk writes than expected. I believe, though, that this would explain at most a factor of 2 of write expansion (user data getting pushed to disk once in the intent log, then again in its final location). If the
