Re: Btrfs progs release 6.6.1

Hi David,

Thanks for the info.

I'm using btrfsprogs 6.5.1-1.2 and my btrfs filesystem is a single 
partition on a single device so it does not seem like the bugfix release 
is related to my issue.

I actually think the issue occurred because of Skype crashing ( although 
it does still seem a little odd to me that would cause the issue ).

Is there a way for btrfs to remove that directory entry which points to 
the inode that does not exist ?

After I removed all the @home snapshots, that got rid of all of them 
items that btrfs check reports EXCEPT for the one in the @home subvolume 
so deleting a subvolume can remove the items, but I really don't want to 
have to delete and restore the @home subvolume to fix it.

And since then btrfs has created new timeline snapshots for @home so 
those obviously have the same issue as the ones I deleted but that 
problem would go away if I can find a way to remove the offending item 
in the @home subvolume.

Is there some way to remove that item ?

Running "ls -al /home/denise/.config/skypeforlinux/blob_storage/" also 
shows that offending item:

     drwx------ 1 denise joe-denise   72 Nov  1 22:49 .
     drwxr-xr-x 1 denise joe-denise 3.7K Nov  1 20:07 ..
     d????????? ? ?      ?             ?            ? 
02179466-b671-4313-8fa5-0eb87d716f92

I tried removing /home/denise/.config/skypeforlinux/blob_storage/ since 
that is the folder that contains the 
i02179466-b671-4313-8fa5-0eb87d716f92 directory item but that fails

     rm -rf /home/denise/.config/skypeforlinux/blob_storage/
/usr/bin/rm: cannot remove 
'/home/denise/.config/skypeforlinux/blob_storage/': Directory not empty
