Files/Folders invisibles with 'ls -a' but can 'cd' to folder

[k g <klimaax@gmail.com>]

Hi


As I say in my subject, I'm facing a weird problem with my btrfs
partition (I already sent this message on reddit /r/btrfs/ )

It's in fact a btrfs partition in a raid5 synology system.



3 days ago, the volume 'crashed' (synology terms) ,however SMART data is
ok and I don't have sector relcocation errors or CRC.... I rebooted
several times , and after dozen of reboots my partition shows up , but 3
TB of 10 TB are missing, I made a scrub but it did made my missing files
appears.



desperately I made a 'cd xyz' in a directory (I remember some of the
folder names) and it works ; and inside this folder I can do "ls" and
all files and subfolders appears .

I made a copy elsewhere of some files and these ones are not corrupted
or bit roted.



I don't want to make a btrfs check --repair of course.



Is there a way to "relink" indexes/root or whatever it is called to
bring back these files/folder visible and accessible with a safe command ?

I'm planning to backup all , is 'btrfs restore' will access to these
"non visible" directories ?



"I saw similar case here : The Directory Who Wasn't There : btrfs
(reddit.com) , but I can't find a reply that solve the problem"
