I would like to begin by thanking everyone who might take the time to read my issue and guide me to a solution.
I am an editor currently working on a movie which workflow went from FCP7 (too outdated and many compatibility issues) to Adobe Premiere Pro CC 2017. I am using a Pegasus R6 10TB as main storage and interface (all rushes, renders etc.). The disk is connected to the iMac (mid-2011, i7 3,4 GHz, 16 Go DDR3, HD 6970M, 10.12 Sierra) via Thunderbolt.
Today during a quite large render session on Adobe Premiere, the software froze and crashed. I restarted the computer with many difficulties which now prompts me "MacOS cannot repair the drive Promise RAID. You can still open or copy files on the disk but cannot save any changes made to the files".
I am aware this must be a permission issue related to the crash but tried every tip to repair the main drive permissions with no result. As a result I cannot open the project in Adobe Premiere anymore since the drive is read only. I cannot manually change the permissions. I tried a lot of workarounds but only failed.
Since then, getting quite desperate since it is impacting the valuable editing time, I tried a migration of the disk array from RAID5 to RAID0 to kind of reset the structure. What I didn't plan on was the time it was gonna take since it has been more than one hour and only 2% of progression. I have to add 7TBs are used on the 10TBs total.
I would like to know if it would be possible to
1) Cancel the disk array migration since it will be probably useless and is currently impacting the performances of my computer (as well as making a ton of noise).
2) Did any of you encounter the issue above (macOS cannot repair the disk) and have a workaround in mind.
Thank you very kindly in advance
