It sounds pretty much like its supposed to operate if your file system tree is potentially corrupted somehow. You may very well need to copy off the data and recreate the file system. Unless of course the underlying block storage has some issues (bad sectors etc.).

I do recall there not yet being a way to gracefully fix a "broken" HAMMER file system.

Perhaps I am wrong and someone else will offer more enlightened feedback.

Out of curiosity when the file system was mounted at boot, did it not fail to mount? It seems like it should have been brought back to a consistent state after your reboot.

When the damaged data is encountered, it causes hammer to report a critical error and remount the file system as READ ONLY.  Thus, I am unable to delete or remove the bad data in any way to recover the file system to an operable state.

Would love to somehow purge it so the volume can be returned to normal operation.  It's a 2TB volume, so I'm hoping I don't have to reformat and re-create the volume.
