I'm also seeing a drive in read-only mode, noticed because of issues I was seeing with Docker.  Although mine is REISERFS setup.  Any suggestions welcome!

@zaker, I splitted your post to its own thread because REISERFS =! BTRFS and that this log extract can indicate other issues.

 

Please share your diagnostics.

 

In any case, REISERFS is not recommanded for years now and you should consider changing it once your immediate issues are solved.

Do you have crashes, I see Warnings and call traces mentioning MACVLAN.

Thanks,

Well, a reboot of the Unraid box did see my drives mounted normally, meaning I can write to the file system again.

I realize that I should probably make the switch, and if I saw an easy button for that, I would.  With 3 little kids, my time is soooo strapped!

Anyway, here's my full diagnostics.
