[Lustre-discuss] Lustre 1.6.2 + 2.6.18 - Directory index full!

[Niklas Edmundsson]

While doing some more file creation tests we hit another interesting 
bug.

We have 13701222 files in one directory, and creating more files there 
fails even though we have lots of free inodes in the filesystem.

On MDS we get this in the kernel log:
[692361.061558] LDISKFS-fs warning (device sdb2): ldiskfs_dx_add_entry: Directory index full!

On client:
# lfs df -i
UUID                    Inodes     IUsed     IFree IUse% Mounted on
hpfs-MDT0000_UUID     35651584  13967459  21684125   39% /hpfs[MDT:0]

filesystem summary:   35651584  13967459  21684125   39% /hpfs
