I'm running the latest and fully updated version of Parallels Desktop with a Windows 10 guest VM.
Because Apple dropped Apple RAID from Disk Manager beginning with El Capitan, I purchased a copy of SoftRAID with the intention of converting my Thunderbolt-connected mirrored array as soon as they re-enable the "convert" functionality in SoftRAID.
(Disk Utility in El Capitan now sees only one, of the two identical disks in my RAID. It sees the two volumes contained in the RAID set, but it no longer recognizes what OS X used to call "slices" (one on each disk) that comprise the mirrored volume. Although arrays created before upgrading to El Capitan still work, there's no way left in OS X 10.11 to configure or manage RAID. I don't even know if El Capitan can rebuild a RAID 0 created under Mavericks if a disk fails, so I thought it would be best to convert to SoftRAID.)
However, the release notes with the latest version of SoftRAID, 5.1, state that "there is a bug in Parallels that can corrupt your Windows virtual machine. We suggest not using Parallels." One might deduce that this is an alleged incompatibility between Parallels and their product, but they do not actually state that. This is particularly alarming to me because I do keep my PVMs on the external RAID where I've experienced zero problems in 15 months since setting it up.
Is there a bug in Parallels that leads to corruption of its VM when the RAID is set up with SoftRaid?
Is there a bug in Parallels that can corrupt a guest VM that resides on any RAID, Applesoft, third party software RAID, or even hardware RAID? I have to ask because the folks at SoftRAID are terribly nonspecific in their claim that there's a the bug in Parallels.
