I have Time Machine (TM) set to use an external networked drive for it's backup, (at some point after a successful backup, I think) the drive will become unavailable. After that, trying to mount the drive again results in the warning that the drive (in fact the entire computer it's physically attached to on the network) is no longer available due to too many users logged in! There are at the most three connected!
I've heard other known troubles exist in this regard with smb connectivity and ML. Is this true? My connectivity is AFP, I think.
The drive is left mounted on the computer being backed up by TM and goes off line as described above by itself. There are other physically attached drives physically attached to the same other computer (MacMini) computer mounted on this computer's desktop. I've never had the same problem on Lion or Snow Leopard and I've been doing backups in the same way for years. Has anybody had this problem??
Should I upgrade the Mini from it's current 10.6.8 OS to Mountain Lion also? Will this make life better or worse in this regard?
I connect the problem to ML because:
- Just went on ML very recently.
- Happens consistently now and hasn't done before.
- Other computer that hosts these drives in running 10.6.8 and this may an incompatibility between OS's.
- Heard of similar issues with smb network connectivity.
- On backup using CCC this problem does not occur.
- The work-around is completely turning off both computers and restarting them, logging in the backup drive all over again. The problem eventually recurs.
- Logging out and in again on the client computer (MacPro) does NOT fix the problem, however.
