SoftRAID 5.5.5 Release Notes (Full Version)
The following info is from the Release Notes in the Softraid 5.5.5 DMG download:
(Some of the items below also apply to the v5.5.5 Lite version - see PDF in the Lite download.)
There is a bug reported in Parallels Desktop 10 software which can cause data corruption in your Windows virtual machines whether running on SoftRAID or AppleRAID volumes. You must install Parallels Desktop 11 if you are running on a SoftRAID or AppleRAID volume.
New features in version 5.5.5:
Added a work-around to SoftRAID driver to help mitigate damage to volumes caused by the Mac OS bug which causes disks to disappear from the Thunderbolt bus.
There is now a man page for SoftRAIDTool. Type "man softraidtool" in a Terminal window to view information about using SoftRAIDTool from the command line.
SoftRAID and SoftRAID Monitor are now localized to Japanese.
Bugs fixed in version 5.5.5:
The SoftRAID driver would cause a kernel panic when the Thunderbolt cable was repeatedly disconnected and reconnected to a ThunderBay with a 4 disk RAID 5 volume.
Fixed a kernel panic which could occur when clearing the i/o counts on a disk. This would happen if you cleared the error count on a disk which was part of a volume and the volume was unmountable because it was missing too many disks.
Fixed a kernel panic which occurs when fsck is run on disks which have a max transfer size of 128 KB.
Fixed a bug which could cause 2 SoftRAID Monitor menus to be displayed simultaneously.
Fixed a bug in the SoftRAID application which caused a white rectangle to be drawn at the left edge of each disk and volume tile. This would remain until the main window was resized.
Fixed a bug in the SoftRAID application which could result in a rebuilt volume which was not in sync. This would happen if you tried 2 times to resize a volume which was out of sync and then let it rebuild after the second resize completed.
The SoftRAID application now restores a disk's label if you certify or zero a disk and then re-initialize it
Fixed a bug which caused the progress indicator in the volume to remain after a user tried to delete a volume which could not be unmounted
Fixed a bug which prevented users from converting volumes back to AppleRAID after the evaluation period had expired
Fixed bug which could prevent installing the SoftRAID driver on startup volumes other than the boot volume
Fixed a bug which prevented the SoftRAIDTool from performing zero, verify and certify disk operations if they were run using the command line interface
Fixed a bug which could cause SoftRAID users to download beta versions of the application by mistake (SR-244).
Fixed a bug prevented adding SoftRAID Read-Only-Secondary volumes back to their original mirror volume. This bug also prevented converting Read-Only-Secondary volumes to new mirror volumes.
