My cache is no longer mountable


Go to solution Solved by JorgeB,

Hi all

 

I'm in version 6.12.0-rc6 and plugins etc are updated. I've just noticed that my 3 cache drives which are formatted btrfs are unmountable and unRAID is telling me to format, but I have stuff on them. 

 

Is this because with all the recent updates I need to select something so the btrfs drives are recognised?

 

I don't really know what to do next coz all was working fine a couple days ago and it's only changed due to the updates. Any help will be much appreciated.

Try this, if the log tree is the only problem it may help:

 

btrfs rescue zero-log /dev/nvme1n1p1

 

This fixed it! Thanks for your help!

 

If you get a spare moment, would you be able to explain how you found the problem? 

 

Should I change the btrfs file system to something else?

The log shows that the log tree failed be read.

Usually something else causes this issue, not directly btrfs related, but you can try a different fs if you prefer, also note that this issue tends to re-occur, if it does would recommend re-formatting the fs.

Thank you so much for your help!

 

If I change file systems, which do you think I should choose? NB it's cache.

G'day again!

 

I've had this issue occur a few times since it first happened, and this solution has fixed it each time. But what would actually cause this to happen?
