io errors- data and parity disk failed / not sure what to do

hi, any ideas what shall I do first with this? I got a pop up a few times saying to replace the disk, but following video on replacing disks says make a copy first, then do a validate. `but this 48tb.. and would take a week and space I can afford. at the moment I am backing up the critical parts, but even that is taking a huge amount of time. 

what does the validate do, will it possibly fix the io issues, or is the warning worse than this. sorry, I don't understand raids well.  what shall I try step by step?

A disk had an IO error, meaning a communication issue. Since it is a single disk, and not all of them, it is suspicious.

I would first five this disk a SoftRAID disk label, called error, or something, so you can identify it later.

then clear the io errors on the volume and disk.

 

Then validate the volume. This is a background task, yes it can take a long time, but you can use your system in the meantime. If you need to do any disk intensive work, change optimization to digital video, while you are doing that work, then change it back to workstation. You can change optimization during a validate. But that will prevent the background disk access from slowing down any work you are doing.

@softraid-support thanks for this.

 

`I have moved the raid to another room so and dedicated a spare laptop to do the validation, however, `I cant get this laptop to mount the `hd, but it is showing the same io errors as the main Mac (that does mount).

 

im keen to be able to access this raid if possible, but without mounting thats tricky. any suggestions (besides doing this on my main computer....)

 

cheers Paul

Error counts are stored on the disks.

If the volume has a "BSD Disk Identifier" in the volume tile, then it is a directory issue, macOS cannot mount it, without a repair.

If the disk identifier is - (i.e, missing) then it is the SoftRAID driver not loading, in most all cases.

reinstall the driver, and "Allow" OWC in System Preferences/Security.

I cant mount my second raid to this other laptop either. so theres something wrong with the laptop causing this. I followed these instructions- i can see the drive in softrad but won't mount. https://www.softraid.com/wp-content/uploads/2020/06/5.8_Volumes_Not_Mounting.pdf

I know my main computer can mount these drives- can I setup the validation then unconnected the computer to use for other things- doesn't the raid keep validating without being connected? if so, what uis the safe way to disconnect after the validation process is started?

Validate needs macOS, and the same system to continue. Its not a rebuild that can occur regardless of system.

if it mounts on one system but not another, that indicates the driver is blocked by macOS. Did you "Allow" OWC in System Preferences/Security when you installed the driver?

help!  I did the 5 day validate, but during that time another disk has had a warning (see below)

this is really serious now, I have 6 years of jobs on this. 

 

I cant see anything to copy over in the finder, so what can I do? I asked an IT friend and he said to replace the dead drive and start a rebuild, but if the second fault drive fails, will I loose everything?

 

Paul

Do not do anything.

the error is a Finder error, saying the volume directory was damaged, macOS attempted to auto mount it, and it is mounted read only. (you must have had some event which remounted the volume, usually a restart)

You can let the validate complete, but do not do anything else.

Did you indicate you do not see your files/folders when you open the volume?

hi, the validation has completed. One drive has failed, and the second drive has predicted failure. I cannot see the files in the finder. The raid is showing up in SoftRAID fine. 

I rang support line, and they said to run disk warrior, but when I started this during the step 5- looking for directories, the raid turned on and off a couple of time randomly. It seemed like the raid was the cause, so I stopped diskwarrior then tested my second raid (thetas healthy) with the same laptop and cable, and it was doing this as well. I tested with another computer and cable and it didn't disconnect, so I suspect the cable/ and or laptop.

Shall I run the diskwarrior again? If this takes a long time (I have 40tb) would it be more beneficial to replace the dead drive instead, as a rebuild will take less time (therefore less time on the predicted drive fail)? Or shall I give up and take this to a data recovery service? I worry about the time, as my drive was copying off files fine before I started the validation. 

 

cheers Paul

Run Disk Warrior. A rebuild does not touch any data, it only corrects "parity" data, which is invisible to macOS.

You can also attach a SoftRAID tech support file and I can guide you next steps, but you need to make sure your backups are up to date first.

Your directory must be badly damaged for no files to show up. When you finish the Disk Warrior scan, click the "Preview" and make sure everything you expect to be present is there and available, before you click "replace", which is not undoable.

hi, here is the report attached. can you please tell me if its better to replace the faulty drive first, so the raid can rebuild with a heathy drive, and then use disk warrior later to rebuild the directory? or won't this work? I worry that disk warrior will take too long and I have a drive that has warnings. 

cheers Paul

1. Run Disk Warrior. Get your data safe ASAP, as you cannot yet replace the failing disk.

2. "Validate" the volume, so you can get it in sync. You have a second disk out of sync, that needs to be addressed before you can replace a disk.

3. Replace the disk.

 

Let me know what happens after you run Disk Warrior. It may not take that long, depending on how damaged the directory is.

thanks.

I just realised after I installed and started that diskwarrior doesnt support Monterey yet, but seems be going... shall I keep going, or stop the process and find a way to get an old os Mac to do his? cheers paul
