Out-of-sync disk + cannot mount volume

Hi there,

An out-of-sync disk prevents a volume from mounting to M1 mac. 

Which in turn prevents rebuilding the out-of-sync disk (... or so it seems).

Problem started before updating operating system (current: Ventura).

Problem is not solved by first uninstalling all SoftRaid components (6 Pro) and installing SoftRaid 7.

Please advise.

The problem is the APFS volume directory is damaged. this is why the volume cannot rebuild. if the volume were OK, then it would rebuild.

Sadly there are no directory rebuild tools available for APFS, like there was Disk Warrior for HFS volumes. APFS was supposed to solve all these directory issues. It seems to work great for internal, built in drives, but not so robust on external disks.

So your solution is restore from backup. If you do not have a current backup, two products which seem to do well at data recovery for APFS are Disk Drill and R-Studio.

Also, I was reminded by another post today, make sure your Samsung blades have macOS compatible firmware. Samsung still ships new models of drives which are not macOS compatible, for months, before offering updated firmware for the apple environment.

Thank you for your quick reply.

Yes, I can delete the volume and restore from back-up (thank you OWC Thunderbay!).

What I cannot do is update the Samsung-firmware. I have looked into this once but as I can recall updating can only be done on a Windows operating system, which I do not have at my disposal.

2 questions:

- Could you please share the disk labels of the Samsung disks that are in need of firmware-updates?

- Is there some kind of workaround - that any of you guys know of - to update Samsung firmware?

Kind regards,

Niels

I do not have any labels, but I have seen this issue for over 5 years, starting with (if I remember) the original 850 Pro drives.

Check on the Samsung page for Apple compatibility. they should show it.

Oh my,

Now it seems that everything starts to fail. Should I be worried or can I just restart. At this moment I'm afraid to do so.

Your missing disks are physically missing. What enclosure are they inside of?

Thank you for your open and honest feedback regarding APFS.

"APFS is not quite yet as stable as it should be ...", is what you said.

Fair enough.

We live and learn, therefore I'm back on HFS.

All 9 disks are up and running again and to answer your question, I use 2 OWC Express units plus a Samsung X5 that sits on my desk and is permanently connected.

All's well that ends well, but I do want to point out the following message. see attachment

It popped up while creating a volume.

Just like earlier this year SoftRaid wants to steer me towards choosing APFS.

Leading me to believe it to be my best option.

Presenting it as the only sensible option, because neither HFS nor ExFat are mentioned.

Long story short, APFS works well ... untill it doesn't.

I've learned that a Raid 4 (format APFS) is rendered useless and the data inaccessible after a single disk fell out-of-sync. Something I find rather unsettling.

For me reliability and peace of mind outweigh performance increase any day.

So it might be wise to update/review/revise this particular in-app message in an upcoming SoftRaid update.

This is only a suggestion, of course.

Can you give me details on what happened? I want to test this. RAID 4 should not cause such an issue, and if it is related to SoftRAID, rather than APFS, I need to test to try to reproduce this.
