After slightly over a month and a half of flawless service, my FreeNAS-8.0.2-RELEASE-amd64 (8288) server has started reporting false drive capacity. It has a raidz1 pool containing 3 (plus a so called "hot spare") 500GB Western Digital Raptor drives. The setup is almost exclusively used as Time Machine server for 5 Mac workstations.
Since the beginning, reported size has been slightly less than 1TB as expected. However as of about 24 hours ago, the reported size (not free space) has dropped to about 4.8GB.
The various Mac workstations started throwing errors that the "Time Machine could not complete the backup" because it was too large for the available 4.8GB of space (See attachment). I don't know if the Time Machine backups running out of space (the pool was getting legitimately full) caused the problem, or if the problem happened and then Time Machine started throwing errors.
I've also included a screen shot of a weekly disk space graphs. You can see right around 24 hours ago, the reported capacity plummets.
Any suggestions on what might be happening here? Are the last month of backups gone? As far as I can see now, all of the historic Time Machine backup data is no longer available to Macs. :(
NOTE: I've seen the following info requested in similar threads. If you need anything else, just ask:
