BTRFS claims that empty directory is not empty and refuses to delete it
Hello!
This is with 3.16-rc4 – stepped back to this one after having two hangs in one
day with 3.16-rc5, see other thread started by me:
martin@merkaba:~/Zeit/undeletable/db_data> ls -lid akonadi
450598 drwx------ 1 martin martin 1232 Jun 22 14:11 akonadi
martin@merkaba:~/Zeit/undeletable/db_data> ls -lai akonadi
insgesamt 0
450598 drwx------ 1 martin martin 1232 Jun 22 14:11 .
450595 drwxr-xr-x 1 martin martin 14 Jun 22 14:11 ..
martin@merkaba:~/Zeit/undeletable/db_data> LANG=C rmdir akonadi
rmdir: failed to remove 'akonadi': Directory not empty
martin@merkaba:~/Zeit/undeletable/db_data#1> LANG=C rm -r akonadi
rm: cannot remove 'akonadi': Directory not empty
martin@merkaba:~/Zeit/undeletable/db_data#1> LANG=C rm -rf akonadi
rm: cannot remove 'akonadi': Directory not empty
martin@merkaba:~/Zeit/undeletable/db_data#1>
Whats this?
I had this weeks ago already and just moved it out of the way at that time,
just now stumbled upon it again.
This is the same BTRFS Dual SSD RAID as mentioned in the other post:
