| Hi all,
I have a Mac Mini (Macmini5,3) running Mac OS X 10.7 Server. I set out to upgrade it to 10.12, and, and with the help of my local Apple store, I discovered that the disk containing the boot volume had started developing bad blocks. As a temporary solution, I allocated a hunk of the second disk in the Mac Mini, previously used for only Time Machine, to now also boot the computer, and I reconfigured Time Machine to start backing up to a new external disk. Long term, I plan to replace the failing disk, but as xkcd-349 so aptly highlighted, my goal at this point is now to simply get the computer back to the way it was.
When I moved the boot volume to the second disk inside the Mac, the computer started panicking at a rate of about 1 panic per day. Each of the panics starts like this:
panic(cpu 2 caller 0xffffff800031ed7c): "/SourceCache/xnu/xnu-1699.32.7/bsd/vfs/vfs_journal.c:2472: jhdr magic corrupted (0x76697270 != 0x4a4e4c78)\n"@/SourceCache/xnu/xnu-1699.32.7/bsd/vfs/vfs_journal.c:2472
Suspecting that the failing disk (which is still inside the computer) may be causing the problem, I disabled journaling on the failing hard drive. The rate of the panics then dropped to about 2 panics per week. Admittedly, due to the short amount of time that has passed (too few data points), it’s difficult to scientifically link the change in the panic frequency to the action of disabling journaling on the failing disk.
Does anyone have any ideas on how to stop these panics?
Thanks, - Andrew Keller
