As of this morning, the Pegasus 2R4 (in Raid 5) attached to a Mac Pro ceased to mount. I have rebooted both, moved the cable on both the computer and the Pegasus. Using the Promise Utility, I cheched for and successfully installed an update. No help. In addition, the utility indicates the Drives are full, whereas last week there was about 3.5 Tb free. I have generated and attached a subsystem report.

I'm having the exact same problem - very frustrating! Anything fixed here?
In my case, The drive eventually rebuilt itself using the 3 remaining drives and then the RAID remounted. I copied the entire contents to a new Pegasus R3 I had bought (it was going to take over 3 weeks for a replacment drive to arrive and a new R3 took days). No files were lost. With the new drive, I will now rebuild the R2 and retask it to another computer.
