Re: High Sierra Installation on Existing RAID 0 Array
CBCCool30 Jun 9, 2017 7:03 AM (in response to tty0746)Not yet. I backed it up and tried to reformat the drives to APFS, but for some reason the RAID always failed or showed up offline, or even created new partitions that were completely unformatted. I eventually just reinstalled Sierra on my original Mac OS Extended (Journaled) RAID 0 setup. I don’t think APFS likes software RAID much... if you figure anything out, let me know.

Re: High Sierra Installation on Existing RAID 0 Array
tty0746 Jun 13, 2017 7:11 AM (in response to CBCCool30)Same here. I've tried all possible scenarios. APFS/RAID0; fails. EJ/RAID0; Successful, but install fails. I was able to format one drive (EJ), and install; but, what's the point? I'm reverting back to Sierra, until a future release becomes available.

Re: High Sierra Installation on Existing RAID 0 Array
Benloh Aug 19, 2017 9:57 AM (in response to bupperz)Doesn't seem like that.
I think it has something to do with APFs and the software controlled RAID.
Maybe there has to be a special APFs-RAID if it's software controlled, so the copy charasteristics can be handled.
This may cause a new RAID management system, that is not compatible with previous software RAIDS

Re: High Sierra Installation on Existing RAID 0 Array
bigtom Aug 25, 2017 12:17 PM (in response to CBCCool30)I finally received an official response from Apple on the bug report. No 10.13 installs on Apple RAID volumes.
"...this looks like correct behavior...we stopped allowing installs to RAID set members in macOS 10.13"

Re: High Sierra Installation on Existing RAID 0 Array
muaddib Aug 29, 2017 11:38 PM (in response to bigtom)I found this on Apple's Website
"Can I boot macOS High Sierra from an APFS-formatted hard disk?
Yes. macOS High Sierra supports Apple File System for both bootable and data volumes."
"Can RAID be used with Apple File System?
Yes. Apple File System does not directly implement software RAID; however APFS-formatted volumes can be combined with an Apple RAID volume to support Striping (RAID 0), Mirroring (RAID 1), and Concatenation (JBOD). APFS-formatted volumes can also be used with direct-attached hardware RAID solutions."

Re: High Sierra Installation on Existing RAID 0 Array
Thy4205 Sep 2, 2017 11:47 AM (in response to CBCCool30)I think I just beat it by simply not installing directly to the RAID partition but restore it. I partitioned a fresh partition for 20GB. Install HS to it. Reboot, boot up with a usb, and then use disk utility to restore the partition to the raid partition. Whoa it boots!
Edit 1: It is HFS+ not APFS at the moment. Im trying to investigate on APFS.
-
Re: High Sierra Installation on Existing RAID 0 Array
Taruga Sep 2, 2017 8:31 PM (in response to Thy4205)If you created the RAID 0 using Disk Utility GUI in latest beta, then I think you don't have APFS as a choice.
But you can have an APFS Raid 0 volume using Terminal:diskutil appleRAID create stripe "HighSierra" apfs disk3 disk4
Don't forget to replace [disk3] and [disk4] with your correct disk id´s
This way you will end up with an APFS RAID 0 (stripe) and then you do the same you did with Disk Utility to restore your previous HS instalation and if that doesn't work with APFS for some reason, then do it like I did with Carbon Copy Cloner V5
-
Re: High Sierra Installation on Existing RAID 0 Array
Thy4205 Sep 2, 2017 9:13 PM (in response to Taruga)Actually I did the steps you mentioned above, but used disk utility instead of CCC to restore the system. (I also tried time machine restore)
With JHFS+ it boots straight away, but with APFS, the partition is showed but it restarts automatically while it boots. The partition was working as I tested it by copying large file to it, it just wont boot. I am happy with JHFS+ at the moment, I will try again with the public release I guess.
-
Re: High Sierra Installation on Existing RAID 0 Array
Taruga Sep 2, 2017 9:23 PM (in response to Thy4205)I don't have any problem booting from my Raid 0 APFS but this is a not very good way to do it because on next update I will have to repeat the same steps to get it working if apple doesn't allow us to use Raid 0 with APFS
-
Re: High Sierra Installation on Existing RAID 0 Array
Thy4205 Sep 5, 2017 12:27 PM (in response to Taruga)Even with JHFS+, I have no luck updating the system. It can download and install the update, but the version doesn't change at all apparently. I guess I need to break the RAID for the future until we find ways to avoid that.

Re: High Sierra Installation on Existing RAID 0 Array
GuillermoA Sep 27, 2017 5:58 AM (in response to rezwits)Oh, this is terrible news. I'm currently running Sierra from a SSD RAID0 I setup during a clean install using Disk Utility, and then installing Sierra.
What does this mean now? I won't be able to simply upgrade to HS?

Re: High Sierra Installation on Existing RAID 0 Array
Riversid_Guy Oct 2, 2017 12:51 PM (in response to CBCCool30)Someone from the more general forums pointed me here, just the place I want to be. Exact same situation as most, running Sierra from a RAID 0 on a pair of SSDs (on a PCI card no less) in a cheesegrater.
So we see 2 very different messages from Apple... honestly, what they have publically posted MUST be what they deliver. The only question following their statement as quoted above is "Can DIsk Utility make a RAID on 2 APFS formatted volumes?" They DO say you can't USE APFS to create the RAID, that makes sense.
According to that, as I have a clone of my boot drive (SSD RAID), theoretically I can upgrade that to HS, break the array, APFS each SSD, create the RAID then clone my updated first clone back to the array. BUT I'd lose my **** completely if I then saw it say it can't boot that way or some stuff like that.
How do we get Apple to really give us a definitive answer?

Re: High Sierra Installation on Existing RAID 0 Array
jeremiah-sypult Oct 4, 2017 12:39 PM (in response to Riversid_Guy)I saw in the APFS Guide FAQ that APFS supports RAID configurations: https://developer.apple.com/library/content/releasenotes/General/RN-macOSSDK-10.13/index.html
There is no mention that AppleRAID support was dropped from the macOS High Sierra Release Notes: https://developer.apple.com/library/content/releasenotes/General/RN-macOSSDK-10.13/index.html
I filed a bug: 34756034

Re: High Sierra Installation on Existing RAID 0 Array
MacSpezialist Oct 8, 2017 12:05 AM (in response to CBCCool30)and one more note:
SSD startup drives get converted to APFS during high sierra install, but not Fusion drives. Internaly they work like Raid's i guess and therefor they stay as HFS+ but the high Sierra install succeeds. I wonder why Apple didnt choose the same path for Software Raid's, if there is still an issue with APFS and Raid volumes … real bummer for my several MacMini Servers that all run SSD Raid1 startup drives for reliability.

Re: High Sierra Installation on Existing RAID 0 Array
MagnusNY Oct 8, 2017 1:29 PM (in response to CBCCool30)I am stunned there is no migration path docs released by Apple, how to convert from AppleRAID to APFS RAID.. Looks like it was all forgotten in the cut and dry transition.

Re: High Sierra Installation on Existing RAID 0 Array
crazeazn Oct 9, 2017 5:08 PM (in response to MagnusNY)Just for anyone else searching, it appears that a clean install of High Sierra with newly made APFS RAID 0 will not work either.
I have a 2012 Mac Mini with 2 Samsung 850 PROs that ran Raid 0 on El Capitan. I'm morbid + I have the luxury of all my data being backed up elsewhere so I wiped the raid array, installed High Sierra via bootable USB on an external SSD, booted from there and then created a new APFS raid with the two Samsungs. Previously, the High Sierra installer would not even let me select the El Capitan created Raid partition at all. However, once I made it a APFS raid, it allowed me to select the drive. Install went 100% until the very end where I get the error message "Could not create a pre-boot volume for APFS install".
I'm trying internet install for ***** and giggles but I'm fairly sure I will get the same result. I hope this saves someone a few hours

Re: High Sierra Installation on Existing RAID 0 Array
Riversid_Guy Oct 10, 2017 2:21 PM (in response to crazeazn)That kinda suspiciously sounds like a different issue, the fact the OS will not create a recovery partition when installing onto a RAID array. Again, how can we get them to speak to us about this issue?

Re: High Sierra Installation on Existing RAID 0 Array
MiamiDano Oct 16, 2017 11:49 AM (in response to crazeazn)Just found this thread and did exactly the same attempt to install after booting to external flash drive and creating APFS RAID on my previous Apple Raid setup. Haver early 2011 MBP with RAID) setup on 2 - 275GB Crucial SSDs.
10.3 will get to 100% and then get error message.
Resored back to my old set up (RAID0) on 10.11.6. Never updated to Sierra.
Figure will have to wait for Apple to update with solution. Just hope will one day be able to update OSX once again.

Re: High Sierra Installation on Existing RAID 0 Array
kmcf Oct 27, 2017 5:28 AM (in response to MiamiDano)Any new updates on this issue? And also, i have the same problem where i can’t install HS on raid, my 2012 mbp is running on os x mavericks at the moment. Is there anyway that I could update it to Sierra? I’m patiently waiting but its rendering my mbp useless since i use it for school and i can’t download MS Office on it due to OS Mavericks being outdated.

Re: High Sierra Installation on Existing RAID 0 Array
kmcf Nov 5, 2017 3:51 PM (in response to nicwilson)Yeah, after I had posted this is when I thought about installing Sierra. I could careless about High Sierra atm since I think it's still a Beta, not that It would install on Raid. But yeah, for those who have apple Raid, Sierra will install on Raid.
My laptop is super fast now although, the battery is draining faster now than it used to be. I could probably only get around 3-4 hours of constant usage. Did you replaced your Battery?

Re: High Sierra Installation on Existing RAID 0 Array
Dzhantov Nov 3, 2017 11:41 AM (in response to Clodinei)They wont fix soon those problem, deliberately want to resolve it, because SSD raid-0 (for example 2 SSD 240GB HyperX Fury cost 260$) on APFS gives you almost 2200 megabyte per sec. read speed and 800 megabyte per sec. write speed, you can have this speed on macbook pro late 2011! How they sell products in 2016 and 2017 if you have almost the same speed on products of 2011? Do not expect to solve this problem soon!!!
-
Re: High Sierra Installation on Existing RAID 0 Array
kmcf Nov 5, 2017 3:53 PM (in response to Clodinei)I wouldn't bother with High Sierra right now. I'd highly recommend staying on Sierra on Raid until High Sierra is fully released.

Re: High Sierra Installation on Existing RAID 0 Array
Frono Sep 28, 2018 4:17 AM (in response to AnserMan)I just tried to install Mojave 10.14 on a dual drive Mini server. It accepts the raid 0, allows me to restore a time machine backup to the drive but gives the "?" when it tries to boot from the drive. I plan to experiment a bit, but it appears 10.14 goes through the whole installation without telling me that I'm doing something wrong, so maybe it will work.
