Weeknote 2026-W18 is cancelled due to illness, plus my Mac is also "sick" with memory corruption issues.

The Dictionary on M1 Mac crashed twice. I ran Disk Utility and my data volume dev/rdisk3s1 was 'found to be corrupt and needs to be repaired'. The log says 'performing deferred repairs', 'it appears to be OK'. But when I run it again the same corrupt message reappears. 😔 In recovery mode, tried running fsck_apfs but can't do anything: 'failed to enable crypto I/O mode for container /dev/rdisk3s1: invalid argument'. Will try turning off fire fault. #Mac #AskFedi #troubleshooting #fsck #apfs

Any partition format suggestions for DAS SPAN HDD Array mounted on macOS? it'll be mounted to mac mini and running like a NAS drive over my network.

I've been using macOS extended (journaled) (bcz less IO to mechanical drive) for external HDDs, but wanted to get some feedback.

Thanks in advance!

Disk Utility still can't check and repair APFS volumes and containers

After years of reading that #TimeMachine backups couldn't be rsync'd and whatnot because hardlinks and more complicated directory hard links.

Something must have changed or the information I was reading was all wrong for networked TimeMachine backups. I believe hard links are heavily used in HFS+ and the newer APFS volumes. However for storing these on a networked share or none Apple filesystem they are placed in a "sparsebundle" which is disk image, on the underlying filesystem is stored as some metadata files and a number of "bands".

With that and TM being finicky at times, I finally decided to try moving my backups to NVMe from spinning rust. And it all worked!

I think it was: https://blog.fosketts.net/2015/07/22/how-to-use-mac-os-x-sparse-bundle-disk-images/ which gave me the right info for how "sparse bundles" work and can safely be rsyncd.

Also a special shout out for https://eclecticlight.co/ the depth of knowledge and the T2M2 utility for analysing TM Logs.

My new storage box is now faster and much quieter (no longer need to restrict backups to not run after 11pm).

Next changes:
- Upgrade networking to 2.5Gbe
- Set up `sanoid` and `syncoid` for zfs snapshots and send them to the spinning rust.

Shiny (and dusty) green motherboard for attention :P

@timoruppell As it turns out it was about the filesystem format. While exFAT supports millions of files per dir and huge partitions, #macos writing to #exFAT is just very slow (and also appears to slow down the more you write).

Reformatting external disks with #APFS made a huge difference - maybe 10 times faster writes and no slowing down during the huge 7z file extraction process.

Extraction toos 5-6 days to exFAT formatted disk and only 6 hours to APFS formatted disk.

@dnanian

How is this whole situation acceptable???!

I can't tell how much space I've used, or have available; I can't tell how much overhead I need…

#Finder, Get Info, #DiskUtility, and #DaisyDisk **all** give me different numbers for how much space I'm using and/or have available…

What a GD clusterfuck. I thought #APFS was supposed to be an improvement…?

@m2m #APFS I read is designed for SSDs which my external drive is not. Has it been fine for you on a non-SSD?

#HFS+ (sometimes called the OS X / macOS format?) has support until 2040 so it's still worth considering if it can reliably work in Windows somehow...
