[Samba] Macs deleting files off RHEL8 server

Wed May 21 01:27:31 UTC 2025

You can check how a mac is set by looking at the disk formatting
For remote drives “SMB” there is a flag  that is set
Are these actual files or are they temp files?

One thing you will see….
Is if you use a remote drive as a “work” drive, osx & certainly windows can generate hundreds of temp files
Which you cannot normally see.
By work,
That means if you are in word & you open a file on a shared remote drive, all the temp files are generated on the remote
Burying its performance, because you see stupidity of  < 500 bytes of action on the  data packets, sometimes less that 80 bytes
Which is a pain since tcp/ip packet size is between 20-120 bytes of control data, you end up sending more header data than actual data.

So are these “real” files.
Next up…
If your file system is THAT unstable , you need to address it…
The system should not “hang up” , unless you were trying to delete files locked by other processes.

Be aware that a “hang” is not always an indication of a “bad” thing., and you should give it a few minutes.

Okay, so the server was changed to case insensitive yesterday morning.

Today, I just watched an instance where files disappeared in real time. User print33 was moving/deleting files from a job on the server.

It got hung up, the server was showing no folders, so we force quit the Finder. The server share unmounted, then we remounted it.

Before the hang up there were 239 folders on the server. Now there’s only 224.

I know this because I had just gone through and made sure all folders were accounted for this morning.

Absolutely stumped as to why this is happening. I’ve sent the sosreport to Red Hat to see if they can decipher anything.

Kind regards,

Thanks for this info! I appreciate it. AFAIK, I've never changed any settings on the Macs re: case sensitivity, so they should be insensitive. Is there a way I can check this?

Kind regards,

You have to be really careful with shares and macs.
Since each mac can be set to either be case sensitive or not.
It is possible for macs to throw all sorts of errors, if they are operating on mixed case systems.

If the mac assumes it is case sensitive and it is not , it can  either delete files or cause file name clashes that throw errors.

Thanks for the confirmation, Roland. I'll have those looked at.

I've gotten some info that because the server is case sensitive, it could
be interfering with Apple's SMB protocol. Any thoughts on that? It is
something I'll look into.
