I have been using Unraid for about 2 years, with 4 platter drives and 1 SSD cache. On Sunday, the 10-year-old SSD failed, but took with it an entire VM which was not being moved to the proper part of the array.
I am not using Mover Helper. The share settings are as follows:
And the logs from the last mover instance run before the drive failure show:

In every instance of that vdisk, it seems to skip moving it.
I'm planning to install a new cache drive this weekend, and I don't want this to happen again. What could have caused this?
Thanks for your help.
