Help with 69845 disk utility error?

[bigsmile01]

Lately, my Mac has been acting slightly weird with finder tasks. For example, if try to unzip a 1MB file in the Finder it can take 3+ minutes! I use OneDrive to store my documents folder. And often the Finder will say it needs to download files that already exist locally. And then it will just get stuck.

Everything was fine when I was on 12.7.2. The issues only happened since I updated to 12.7.3.

I decided to run First Aid in Disk Utility.

This is how my Mac drive is set up:

When I run First Aid on “Macintosh HD - Data”, I get the following error message:

Running First Aid on “Macintosh HD - Data” (disk1s5)

Operation successful.

First Aid found corruption that needs to be repaired. To repair the startup volume, run First Aid from Recovery.

How can I fix this? I am surprised there is corruption, because I only did a clean reinstall a few months ago.

Steps I have tried:

• Running Disk Utility from Recovery (e.g. by holding down CMD+R during start up). It produces the exact same error message.
• Running first Aid on the other drives on my system (When I do this, First Aid completes successful. It's only on “Macintosh HD - Data” it produces the error).

Environment:

• MacOS 12.7.3 (21H1015)
• MacBookPro11,5 (15-inch, Mid 2015)

From recovery, unmount the volumes before running First Aid and, as suggested in the error message and Apple's documentation:
" Try running fsck against the entire APFS container instead of a volume"
“Repair volumes, then containers, then disks”

Thanks for your help! I tried unmounting the disk, but using first aid still produces the same error as in the opening post.

I am struggling with running fsck. I followed this guide on Apple Insider. I opened terminal and entered diskutil list.

This is what it displayed:

/dev/disk0 (internal, physical):

I then entered "/sbin/fsck -fy". But it just says
"warning: option -f is not implemented, ignoring
error: container /dev/rdisk1 is mounted"

It says this, even though I clicked on unmount on disk utility.

Any ideas how to run the fsck command? Thanks!

From Terminal, try:

diskutil umount /dev/disk1s5

then

fsck_apfs /dev/disk1s5

diskutil umount /dev/disk1s5

fsck_apfs /dev/disk1s5

Thank you so much for your continued help.

I tried running the commands both from booting into Recovery and from inside MacOS.


From Recovery:
When I try the unmount command, it says the following:

Unmount failed for /dev/disk1s5

When I try the fsck command, it says

fsck_adps: command not found.

From MacOS:
When I try the unmount command, it says the following:

Volume Macintosh HD - Data on disk1s5 failed to unmount: dissented by PID 1 (/sbin/launchd)
Dissenter parent PPID 0 (kernel_task)

When I try the fsck command, it says:

error: container /dev/rdisk1 is mounted with write access.

From your first post, I see that it performs on rdisk1s5, not disk1s5.
Try from Recovery

diskutil umount /dev/rdisk1s5

and

fsck_apfs /dev/rdisk1s5

Don't misspell it as fsck_adps, it's FSCK_APFS

Thanks again for the continued help:

When I try diskutil umount /dev/rdisk1s5 in recovery, it says:
Unmount failed for /dev/rdisk1s5

When I try fsck_apfs /dev/rdisk1s5, it says:

Run diskutil list before to ensure that the disk number is correct.
If you have a bootable installer, boot from it and try with Disk Utility or from Terminal.

Thank you so, so, so much! I made a bootable installer and was able to unmount the disk and run FSCK check. It found some orphans which it told me to delete. I was then able to successfully run first aid on all volumes and all the weirdness has gone.

Thank you so much for taking the time to help me, and also for being so patient. 👍
